+# BDFR Web Interface - Docker Deployment Guide
+
+This guide covers running the BDFR Web Interface with full BDFR backend support using Docker.
+
+## Quick Start
+
+### Prerequisites
+
+- Docker Engine 20.10 or later
+- Docker Compose 2.0 or later
+- At least 2GB of free disk space
+
+### Basic Setup
+
+1. **Clone the repository** (if you haven't already):
+   ```bash
+   git clone <repository-url>
+   cd BDFR_Web
+   ```
+
+2. **Create required directories**:
+   ```bash
+   mkdir -p downloads data config
+   ```
+
+3. **Configure environment variables** (optional but recommended):
+   ```bash
+   cp web_interface/.env.example .env
+   # Edit .env with your Reddit OAuth credentials
+   ```
+
+4. **Start the container**:
+   ```bash
+   docker-compose up -d
+   ```
+
+5. **Access the web interface**:
+   Open your browser to `http://localhost:8000`
+
+## Configuration
+
+### Environment Variables
+
+Create a `.env` file in the project root with the following variables:
+
+```env
+# Docker User Configuration (Important for file permissions)
+# Set these to match your host user's UID/GID to avoid permission issues
+# Find your UID/GID by running: id (on Linux/Mac) or wsl id (on Windows WSL)
+PUID=1000
+PGID=1000
+
+# Reddit OAuth Configuration (Required for authenticated features)
+BDFR_CLIENT_ID=your_client_id_here
+BDFR_CLIENT_SECRET=your_client_secret_here
+BDFR_REDIRECT_URI=http://localhost:8000/auth/callback
+
+# Server Configuration (Optional)
+HOST=0.0.0.0
+PORT=8000
+DEBUG=false
+```
+
+### Getting Reddit OAuth Credentials
+
+1. Go to https://www.reddit.com/prefs/apps
+2. Click "Create App" or "Create Another App"
+3. Fill in the form:
+   - **Name**: BDFR Web Interface (or your choice)
+   - **App type**: Select "web app"
+   - **Description**: (optional)
+   - **About URL**: (optional)
+   - **Redirect URI**: `http://localhost:8000/auth/callback`
+4. Click "Create app"
+5. Copy the **client ID** (under the app name) and **client secret**
+
+### Volume Mounts
+
+The Docker setup uses two volume mounts:
+
+| Host Path | Container Path | Purpose |
+|-----------|----------------|---------|
+| `./downloads` | `/app/downloads` | All Reddit downloads are stored here |
+| `./data` | `/app/data` | SQLite databases, scheduled tasks, and BDFR configuration |
+
+**Data Directory Structure:**
+```
+./data/
+├── bdfr-config/          # BDFR configuration and OAuth tokens
+│   ├── config.cfg        # BDFR settings
+│   ├── log_output.txt    # BDFR logs
+│   └── oauth_tokens/     # Reddit authentication tokens
+├── scheduled_tasks.db    # Web interface scheduled tasks
+└── scheduler_jobs.db     # APScheduler job store
+```
+
+## Usage
+
+### Managing the Container
+
+**Start the container:**
+```bash
+docker-compose up -d
+```
+
+**Stop the container:**
+```bash
+docker-compose down
+```
+
+**View logs:**
+```bash
+docker-compose logs -f
+```
+
+**Restart the container:**
+```bash
+docker-compose restart
+```
+
+**Rebuild after code changes:**
+```bash
+docker-compose up -d --build
+```
+
+### Using the Web Interface
+
+1. Navigate to `http://localhost:8000`
+2. Use the web UI to:
+   - Download from subreddits
+   - Download from users
+   - Schedule recurring downloads
+   - Monitor active downloads
+   - View download history
+
+### Using BDFR CLI Inside Container
+
+You can also use the BDFR command-line tool directly:
+
+**Enter the container:**
+```bash
+docker exec -it bdfr-web-interface bash
+```
+
+**Run BDFR commands:**
+```bash
+# Download from a subreddit
+bdfr download /app/downloads --subreddit Python -L 10
+
+# Download from a user
+bdfr download /app/downloads --user reddituser --submitted -L 100
+
+# Archive posts
+bdfr archive /app/downloads --subreddit all -L 500
+
+# Clone (download + archive)
+bdfr clone /app/downloads --subreddit EarthPorn -L 50
+```
+
+**One-line BDFR commands:**
+```bash
+# Download without entering the container
+docker exec bdfr-web-interface bdfr download /app/downloads --subreddit Python -L 10
+
+# View BDFR version
+docker exec bdfr-web-interface bdfr --version
+
+# View BDFR help
+docker exec bdfr-web-interface bdfr download --help
+```
+
+## Advanced Configuration
+
+### Custom Port
+
+To run on a different port, modify [`docker-compose.yml`](docker-compose.yml:11):
+
+```yaml
+ports:
+  - "3000:8000"  # Host port 3000, container port 8000
+```
+
+Or set the PORT environment variable:
+```env
+PORT=3000
+```
+
+### Custom Download Directory
+
+Mount a different host directory for downloads:
+
+```yaml
+volumes:
+  - /path/to/your/downloads:/app/downloads
+  - ./data:/app/data
+```
+
+### BDFR Configuration File
+
+BDFR configuration is automatically stored in `./data/bdfr-config/`. You can customize it by creating `./data/bdfr-config/config.cfg`:
+
+```cfg
+[DEFAULT]
+client_id = your_client_id
+client_secret = your_client_secret
+scopes = identity, read, history, mysubreddits
+
+[bdfr]
+max_wait_time = 120
+time_format = %Y-%m-%d_%H-%M-%S
+```
+
+**Note:** BDFR will automatically create this directory and configuration file on first run.
+
+### Resource Limits
+
+Add resource constraints in [`docker-compose.yml`](docker-compose.yml):
+
+```yaml
+services:
+  bdfr-web:
+    # ... other configuration ...
+    deploy:
+      resources:
+        limits:
+          cpus: '2'
+          memory: 2G
+        reservations:
+          cpus: '1'
+          memory: 512M
+```
+
+## Troubleshooting
+
+### Container Won't Start
+
+**Check logs:**
+```bash
+docker-compose logs bdfr-web
+```
+
+**Verify ports aren't in use:**
+```bash
+# Windows
+netstat -ano | findstr :8000
+
+# Linux/Mac
+lsof -i :8000
+```
+
+**Rebuild the image:**
+```bash
+docker-compose down
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+### Permission Issues
+
+If you encounter permission errors with volumes (e.g., "Permission denied" when creating directories):
+
+**Solution 1: Configure PUID/PGID (Recommended)**
+
+Set `PUID` and `PGID` in your `.env` file to match your host user:
+
+```bash
+# Find your UID and GID
+id
+
+# Example output: uid=1001(username) gid=1001(groupname)
+# Add to .env file:
+PUID=1001
+PGID=1001
+```
+
+Then restart the container:
+```bash
+docker-compose down
+docker-compose up -d
+```
+
+**Solution 2: Fix Host Directory Permissions**
+
+**Linux/Mac:**
+```bash
+sudo chown -R $USER:$USER downloads data config
+chmod -R 755 downloads data config
+```
+
+**TrueNAS/NAS Systems:**
+When using network shares or NAS storage:
+1. Find your NAS user's UID/GID (usually in user management settings)
+2. Set `PUID` and `PGID` in `.env` to match your NAS user
+3. Ensure the NAS user has read/write permissions on mounted shares
+
+**Windows:**
+Ensure Docker Desktop has access to the drive where the project is located (Settings → Resources → File Sharing).
+
+**Why this matters:**
+The container runs as a specific user (default UID 1000). If your host directories are owned by a different user, the container won't be able to write to them. Setting `PUID` and `PGID` tells Docker to run the container as your host user, matching permissions.
+
+### Downloads Not Appearing
+
+1. Check volume mounts are correct:
+   ```bash
+   docker inspect bdfr-web-interface | grep -A 10 Mounts
+   ```
+
+2. Verify download directory inside container:
+   ```bash
+   docker exec bdfr-web-interface ls -la /app/downloads
+   ```
+
+3. Check container logs for errors:
+   ```bash
+   docker-compose logs -f bdfr-web
+   ```
+
+### Permission Denied Errors
+
+If you see errors like "Permission denied: '/usr/local/lib/python3.11/site-packages/bdfr/default_config.cfg'":
+
+1. Verify the BDFR config directory exists and is writable:
+   ```bash
+   docker exec bdfr-web-interface ls -la /app/data/bdfr-config
+   ```
+
+2. Check environment variables are set correctly:
+   ```bash
+   docker exec bdfr-web-interface env | grep BDFR
+   ```
+
+3. If the directory doesn't exist or has wrong permissions:
+   ```bash
+   docker-compose down
+   docker-compose up -d --build
+   ```
+
+### OAuth Authentication Issues
+
+1. Verify credentials in `.env` or [`docker-compose.yml`](docker-compose.yml)
+2. Ensure redirect URI matches exactly: `http://localhost:8000/auth/callback`
+3. Check Reddit app settings at https://www.reddit.com/prefs/apps
+4. Restart container after changing credentials:
+   ```bash
+   docker-compose restart
+   ```
+
+### High Memory Usage
+
+BDFR can use significant memory when downloading large files or many files simultaneously:
+
+1. Monitor memory usage:
+   ```bash
+   docker stats bdfr-web-interface
+   ```
+
+2. Add memory limits (see Resource Limits above)
+
+3. Reduce concurrent downloads by limiting the number of simultaneous operations
+
+### Database Locked Errors
+
+If you see SQLite database locked errors:
+
+1. Ensure only one instance is running:
+   ```bash
+   docker ps | grep bdfr
+   ```
+
+2. Stop all instances and restart:
+   ```bash
+   docker-compose down
+   docker-compose up -d
+   ```
+
+## Maintenance
+
+### Backing Up Data
+
+**Backup downloads and database:**
+```bash
+# Create backup directory
+mkdir -p backups
+
+# Backup downloads
+tar -czf backups/downloads-$(date +%Y%m%d).tar.gz downloads/
+
+# Backup database
+cp -r data/ backups/data-$(date +%Y%m%d)/
+```
+
+**Automated backup script** (Linux/Mac):
+```bash
+#!/bin/bash
+# backup.sh
+BACKUP_DIR="backups"
+DATE=$(date +%Y%m%d_%H%M%S)
+
+mkdir -p "$BACKUP_DIR"
+tar -czf "$BACKUP_DIR/bdfr-backup-$DATE.tar.gz" downloads/ data/
+
+# Keep only last 7 days of backups
+find "$BACKUP_DIR" -name "bdfr-backup-*.tar.gz" -mtime +7 -delete
+```
+
+### Updating the Container
+
+**Pull latest changes:**
+```bash
+git pull origin main
+docker-compose down
+docker-compose build --no-cache
+docker-compose up -d
+```
+
+**Update only Docker image:**
+```bash
+docker-compose pull
+docker-compose up -d
+```
+
+### Cleaning Up
+
+**Remove stopped containers:**
+```bash
+docker-compose down
+```
+
+**Remove containers and volumes:**
+```bash
+docker-compose down -v
+```
+
+**Remove images:**
+```bash
+docker-compose down --rmi all
+```
+
+**Full cleanup (including downloads):**
+```bash
+docker-compose down -v --rmi all
+rm -rf downloads/ data/
+```
+
+## Security Considerations
+
+### Production Deployment
+
+For production use, consider:
+
+1. **Use HTTPS**: Set up a reverse proxy (nginx/Traefik) with SSL
+2. **Secure credentials**: Use Docker secrets or vault for sensitive data
+3. **Network isolation**: Use custom networks and restrict access
+4. **Regular updates**: Keep the container and dependencies updated
+5. **Monitor logs**: Set up log aggregation and monitoring
+6. **Backup strategy**: Implement automated backups
+
+### Example Nginx Reverse Proxy
+
+```nginx
+server {
+    listen 80;
+    server_name bdfr.example.com;
+
+    location / {
+        proxy_pass http://localhost:8000;
+        proxy_set_header Host $host;
+        proxy_set_header X-Real-IP $remote_addr;
+        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
+        proxy_set_header X-Forwarded-Proto $scheme;
+        
+        # WebSocket support
+        proxy_http_version 1.1;
+        proxy_set_header Upgrade $http_upgrade;
+        proxy_set_header Connection "upgrade";
+    }
+}
+```
+
+## Performance Optimization
+
+### Build Performance
+
+**Use BuildKit for faster builds:**
+```bash
+DOCKER_BUILDKIT=1 docker-compose build
+```
+
+**Multi-stage build** is already implemented in the [`Dockerfile`](Dockerfile) to minimize image size.
+
+### Runtime Performance
+
+1. **Allocate sufficient resources** (see Resource Limits)
+2. **Use SSD storage** for downloads directory
+3. **Optimize network** for faster downloads
+4. **Monitor container health**:
+   ```bash
+   docker inspect --format='{{.State.Health.Status}}' bdfr-web-interface
+   ```

+# Publishing BDFR Web Interface to Docker Hub
+
+This guide covers how to build and push the Docker image to Docker Hub.
+
+## Prerequisites
+
+1. **Docker Hub Account**: Create one at https://hub.docker.com if you don't have one
+2. **Docker installed**: Ensure Docker is running on your machine
+
+## Step 1: Login to Docker Hub
+
+Open your terminal and login:
+
+```bash
+docker login
+```
+
+Enter your Docker Hub username and password when prompted.
+
+## Step 2: Build the Image with Proper Tagging
+
+Build the image with your Docker Hub username and desired repository name:
+
+```bash
+# Replace 'yourusername' with your actual Docker Hub username
+# Replace 'bdfr-web' with your desired repository name (or keep it)
+
+docker build -t yourusername/bdfr-web:latest .
+
+# You can also add version tags
+docker build -t yourusername/bdfr-web:latest -t yourusername/bdfr-web:1.0.0 .
+```
+
+**Example:**
+```bash
+docker build -t danielsmith/bdfr-web:latest -t danielsmith/bdfr-web:1.0.0 .
+```
+
+## Step 3: Test the Image Locally (Optional but Recommended)
+
+Before pushing, verify the image works:
+
+```bash
+docker run -d -p 8000:8000 \
+  -v $(pwd)/downloads:/downloads \
+  -v $(pwd)/data:/app/data \
+  --name bdfr-test \
+  yourusername/bdfr-web:latest
+```
+
+Visit `http://localhost:8000` to verify it works, then clean up:
+
+```bash
+docker stop bdfr-test
+docker rm bdfr-test
+```
+
+## Step 4: Push to Docker Hub
+
+Push the image to Docker Hub:
+
+```bash
+# Push latest tag
+docker push yourusername/bdfr-web:latest
+
+# If you created a version tag, push that too
+docker push yourusername/bdfr-web:1.0.0
+```
+
+## Step 5: Verify the Push
+
+1. Go to https://hub.docker.com
+2. Navigate to your repositories
+3. You should see `bdfr-web` listed
+4. Click on it to see tags and details
+
+## Using the Published Image
+
+Others can now pull and use your image:
+
+```bash
+docker pull yourusername/bdfr-web:latest
+docker run -d -p 8000:8000 -v ./downloads:/downloads yourusername/bdfr-web:latest
+```
+
+Or using docker-compose, update [`docker-compose.yml`](docker-compose.yml):
+
+```yaml
+services:
+  bdfr-web:
+    image: yourusername/bdfr-web:latest  # Replace 'build:' section with this
+    # ... rest of configuration
+```
+
+## Automated Build with Docker Hub
+
+You can set up automated builds that trigger when you push to GitHub:
+
+1. Go to https://hub.docker.com
+2. Navigate to your repository
+3. Click "Builds" tab
+4. Click "Configure Automated Builds"
+5. Connect your GitHub account
+6. Select your repository
+7. Configure build rules (e.g., build on push to main branch)
+
+## Multi-Platform Builds (Optional)
+
+To build for multiple architectures (amd64, arm64, etc.):
+
+### Setup buildx (one-time setup)
+
+```bash
+# Create a new builder
+docker buildx create --name multiplatform --use
+
+# Bootstrap the builder
+docker buildx inspect --bootstrap
+```
+
+### Build and push multi-platform image
+
+```bash
+docker buildx build \
+  --platform linux/amd64,linux/arm64 \
+  -t yourusername/bdfr-web:latest \
+  -t yourusername/bdfr-web:1.0.0 \
+  --push \
+  .
+```
+
+This creates images that work on both x86_64 (Intel/AMD) and ARM64 (Apple Silicon, Raspberry Pi, etc.).
+
+## Updating Your Published Image
+
+When you make changes:
+
+1. **Update version**: Increment version in tags (e.g., 1.0.0 → 1.0.1)
+2. **Rebuild**: 
+   ```bash
+   docker build -t yourusername/bdfr-web:latest -t yourusername/bdfr-web:1.0.1 .
+   ```
+3. **Push**:
+   ```bash
+   docker push yourusername/bdfr-web:latest
+   docker push yourusername/bdfr-web:1.0.1
+   ```
+
+## Best Practices
+
+### Tagging Strategy
+
+- `latest`: Always points to the most recent stable build
+- `1.0.0`, `1.0.1`: Specific version tags for reproducibility
+- `1.0`, `1`: Major/minor version tags
+- `dev`: Development/unstable builds
+
+Example tagging:
+```bash
+docker build -t yourusername/bdfr-web:latest \
+             -t yourusername/bdfr-web:1.0.1 \
+             -t yourusername/bdfr-web:1.0 \
+             -t yourusername/bdfr-web:1 .
+```
+
+### Repository Description
+
+Add a good description to your Docker Hub repository:
+
+1. Go to your repository on Docker Hub
+2. Click "Description" tab
+3. Add a README with:
+   - What the image does
+   - How to use it
+   - Environment variables
+   - Volume mounts
+   - Example docker-compose.yml
+
+### Size Optimization
+
+Current image uses multi-stage builds and is already optimized. To check size:
+
+```bash
+docker images yourusername/bdfr-web
+```
+
+## Complete Script
+
+Here's a complete script to build and push (save as `publish-docker.sh`):
+
+```bash
+#!/bin/bash
+set -e
+
+# Configuration
+DOCKER_USERNAME="yourusername"
+IMAGE_NAME="bdfr-web"
+VERSION="1.0.0"
+
+# Build
+echo "Building Docker image..."
+docker build -t ${DOCKER_USERNAME}/${IMAGE_NAME}:latest \
+             -t ${DOCKER_USERNAME}/${IMAGE_NAME}:${VERSION} .
+
+# Test
+echo "Testing image..."
+docker run --rm ${DOCKER_USERNAME}/${IMAGE_NAME}:latest bdfr --version
+
+# Login (if not already logged in)
+echo "Logging in to Docker Hub..."
+docker login
+
+# Push
+echo "Pushing to Docker Hub..."
+docker push ${DOCKER_USERNAME}/${IMAGE_NAME}:latest
+docker push ${DOCKER_USERNAME}/${IMAGE_NAME}:${VERSION}
+
+echo "Done! Image published to:"
+echo "  docker pull ${DOCKER_USERNAME}/${IMAGE_NAME}:latest"
+echo "  docker pull ${DOCKER_USERNAME}/${IMAGE_NAME}:${VERSION}"
+```
+
+Make it executable:
+```bash
+chmod +x publish-docker.sh
+./publish-docker.sh
+```
+
+## Troubleshooting
+
+### "denied: requested access to the resource is denied"
+
+- Make sure you're logged in: `docker login`
+- Verify your username in the image tag matches your Docker Hub username
+- Check that the repository exists or that you have permissions
+
+### "image not found" after push
+
+- Wait a few minutes - Docker Hub indexing can be delayed
+- Refresh the Docker Hub web page
+- Try pulling: `docker pull yourusername/bdfr-web:latest`
+
+### Large image size
+
+Current image should be ~500-800MB. If larger:
+- Check that `.dockerignore` is working
+- Verify multi-stage build is being used
+- Clean up any unnecessary files in the image
+
+## Private Repositories
+
+To make your repository private:
+
+1. Go to Docker Hub repository settings
+2. Change visibility to "Private"
+3. Users will need to login to pull: `docker login` before `docker pull`

+### Docker Deployment
+
+The BDFR Web Interface provides a complete Docker setup with both the CLI tool and web interface. This is the easiest way to get started:
+
+**Quick Start (Linux/Mac):**
+```bash
+chmod +x docker-quick-start.sh
+./docker-quick-start.sh
+```
+
+**Quick Start (Windows):**
+```cmd
+docker-quick-start.bat
+```
+
+**Manual Start:**
+```bash
+docker-compose up -d
+```
+
+The web interface will be available at `http://localhost:8000`. All downloads are stored in the `./downloads` directory on your host machine.
+
+For detailed Docker documentation, including configuration, volume management, and troubleshooting, see [DOCKER.md](DOCKER.md).
+
+
 ## Usage
 
 The BDFR works by taking submissions from a variety of "sources" from Reddit and then parsing them to download. These sources might be a subreddit, multireddit, a user list, or individual links. These sources are combined and downloaded to disk, according to a naming and organisational scheme defined by the user.

+# Scheduled Downloads Implementation Plan
+
+## Overview
+This document outlines the implementation plan for adding scheduled download functionality to the BDFR Web Interface. Users will be able to configure downloads that run automatically on a daily schedule, perfect for keeping up with new content from their favorite subreddits or users.
+
+## Requirements Summary
+- **Database**: SQLite with SQLAlchemy ORM
+- **Scheduling**: Daily frequency (runs every 24 hours)
+- **UI Approach**: Simple - checkbox in Advanced Options + management section on main page
+- **Time Filter**: Automatically set to "last day" for daily runs
+- **Duplicate Handling**: Works with existing no-dupes functionality
+- **Deployment**: Docker container environment
+- **Execution Model**: **Sequential only - one task at a time, queued execution**
+
+## Architecture
+
+### 1. Database Schema
+
+#### ScheduledTask Table
+```python
+class ScheduledTask:
+    id: UUID (Primary Key)
+    name: str  # User-friendly name for the task
+    enabled: bool  # Whether task is active
+    
+    # Download Configuration
+    source_type: str  # "subreddit" or "user"
+    source_name: str  # Name of subreddit or username
+    download_mode: str  # "download", "archive", or "clone"
+    
+    # Filter Options
+    limit: int
+    sort: str  # "hot", "top", "new", etc.
+    time_filter: str  # Always "day" for daily tasks
+    min_score: int (optional)
+    no_dupes: bool  # Always true for scheduled tasks
+    simple_check: bool
+    
+    # Scheduling
+    schedule_frequency: str  # "daily" (extensible for future: "weekly", "custom")
+    run_time: time  # Time of day to run (e.g., "02:00:00")
+    timezone: str  # User's timezone (default: UTC)
+    
+    # Metadata
+    created_at: datetime
+    updated_at: datetime
+    last_run_at: datetime (nullable)
+    next_run_at: datetime
+    
+    # Authentication
+    auth_state: str (nullable)  # For authenticated downloads
+```
+
+#### TaskExecutionHistory Table
+```python
+class TaskExecutionHistory:
+    id: UUID (Primary Key)
+    task_id: UUID (Foreign Key -> ScheduledTask)
+    
+    # Execution Details
+    started_at: datetime
+    completed_at: datetime (nullable)
+    status: str  # "success", "failed", "running", "queued"
+    
+    # Results
+    items_found: int
+    items_downloaded: int
+    error_message: str (nullable)
+    
+    # Link to download
+    download_id: str  # Links to active_downloads tracking
+```

+alembic>=1.12.0  # For database migrations
+apscheduler>=3.10.0  # For task scheduling
+```
+
+#### API Endpoints
+
+**Scheduled Tasks CRUD:**
+- `POST /api/scheduled-tasks` - Create new scheduled task
+- `GET /api/scheduled-tasks` - List all scheduled tasks
+- `GET /api/scheduled-tasks/{task_id}` - Get specific task details
+- `PUT /api/scheduled-tasks/{task_id}` - Update task configuration
+- `DELETE /api/scheduled-tasks/{task_id}` - Delete task
+- `POST /api/scheduled-tasks/{task_id}/toggle` - Enable/disable task
+- `POST /api/scheduled-tasks/{task_id}/run-now` - Trigger immediate execution (adds to queue)
+
+**Task History & Queue:**
+- `GET /api/scheduled-tasks/{task_id}/history` - Get execution history
+- `GET /api/scheduled-tasks/history/recent` - Get recent executions across all tasks
+- `GET /api/scheduled-tasks/queue` - Get current task queue status
+
+### 3. Sequential Task Queue System
+
+#### Task Queue Manager (`task_queue.py`)
+
+**Core Concept**: Only one scheduled download can run at a time. When multiple tasks are triggered (either by schedule or "Run Now"), they are queued and executed sequentially.
+
+```python
+import asyncio
+from typing import Optional, List, Dict
+from datetime import datetime
+import logging
+
+logger = logging.getLogger(__name__)
+
+class TaskQueue:
+    """
+    Manages sequential execution of scheduled download tasks.
+    Ensures only one task runs at a time.
+    """
+    
+    def __init__(self):
+        self.queue: asyncio.Queue = asyncio.Queue()
+        self.current_task: Optional[str] = None  # Current task_id being executed
+        self.is_processing: bool = False
+        self.worker_task: Optional[asyncio.Task] = None

+
+### 8. Implementation Steps
+
+1. **Backend Foundation** (Steps 4-5)
+   - Add SQLAlchemy and APScheduler to [`requirements.txt`](web_interface/requirements.txt:1)
+   - Create [`database.py`](web_interface/app/database.py) with Docker-aware paths
+   - Create [`models.py`](web_interface/app/models.py) with ScheduledTask and TaskExecutionHistory models
+   - Initialize database on app startup
+
+2. **Task Queue System** (Step 7)
+   - Create [`task_queue.py`](web_interface/app/task_queue.py) with sequential queue manager
+   - Implement queue worker with blocking execution
+   - Add queue status tracking and reporting
+
+3. **Scheduler Service** (Step 7 continued)
+   - Create [`scheduler.py`](web_interface/app/scheduler.py) with Docker-aware APScheduler
+   - Integrate with task queue (scheduler adds to queue, doesn't execute directly)
+   - Implement `wait_for_download_completion()` to block until download finishes
+   - Add scheduler lifecycle hooks to [`main.py`](web_interface/app/main.py:1)
+
+4. **API Endpoints** (Step 6)
+   - Create [`scheduled_tasks.py`](web_interface/app/scheduled_tasks.py) with CRUD operations
+   - Add routes to [`main.py`](web_interface/app/main.py:1)
+   - Implement task toggle, delete, and run-now (with queue)
+   - Add queue status endpoint
+
+5. **Frontend - Form** (Step 8)
+   - Add "Run Daily" checkbox to Advanced Options in [`index.html`](web_interface/templates/index.html:1)
+   - Add conditional schedule configuration fields
+   - Update form submission logic in [`app.js`](web_interface/static/js/app.js:1)
+   - Auto-detect browser timezone
+
+6. **Frontend - Management** (Step 9)
+   - Add Scheduled Tasks section to [`index.html`](web_interface/templates/index.html:1)
+   - Add queue status indicator
+   - Implement task card rendering with queue status
+   - Add toggle, delete, and run-now functions to [`app.js`](web_interface/static/js/app.js:1)
+   - Add queue status polling
+
+7. **Integration** (Steps 10-11)
+   - Connect scheduler to BDFR API via [`create_download_with_bdfr_api()`](web_interface/app/main.py:373)
+   - Implement automatic `time_filter="day"` for scheduled tasks
+   - Add execution history tracking
+   - Ensure sequential execution with proper blocking
+
+8. **Testing** (Step 14)
+   - Test task creation, editing, deletion
+   - Test queue functionality (multiple tasks, sequential execution)
+   - Test "Run Now" adds to queue correctly
+   - Test priority (manual tasks run before scheduled)
+   - Test container restart persistence
+   - Verify only one task runs at a time
+
+## Key Features
+
+### Sequential Execution (NEW)
+- **Task Queue**: All scheduled downloads go through a FIFO queue
+- **Blocking Execution**: Each task blocks until its download completes
+- **No Concurrency**: Only one download runs at a time, preventing system overload
+- **Priority System**: Manual "Run Now" tasks get priority over scheduled tasks
+- **Queue Status**: Users can see queue size and currently running task
+
+### Docker-Specific Features
+- **Persistent Storage**: SQLite database and downloads persist via volume mounts
+- **Container Restarts**: APScheduler with job store survives restarts, queue rebuilds on startup
+- **Timezone Handling**: User timezone stored, converted to UTC for container execution
+- **Logging**: Structured logging for container environment
+- **Health Checks**: Scheduler and queue status included in health endpoint
+
+### Automatic Configuration for Scheduled Tasks
+- **time_filter**: Always set to "day" - ensures only last 24 hours of content
+- **no_dupes**: Always enabled - prevents re-downloading same content
+- **Timezone handling**: Store user timezone, convert to UTC for execution, display in user timezone
+- **Sequential execution**: Guaranteed one-at-a-time processing
+
+### Smart Duplicate Prevention
+When a scheduled task runs:
+1. BDFR checks existing hashes (if no_dupes enabled)
+2. Only downloads new content from last 24 hours
+3. Skips content already downloaded in previous runs
+
+### Execution Tracking
+- Every run creates a history record
+- Tracks success/failure status
+- Records items found vs. items downloaded
+- Links to the actual download progress for real-time monitoring
+- Shows queue position and current task status
+
+### User Experience
+- Simple checkbox to schedule any download
+- Visual indication of enabled/disabled tasks
+- Queue status badge shows pending tasks
+- Currently running task highlighted
+- Next run time displayed in user's local timezone
+- One-click to add task to queue immediately
+- Easy enable/disable without deleting task
+- Queue position shown when manually running tasks
+
+## Sequential Execution Examples
+
+### Scenario 1: Multiple Scheduled Tasks
+```
+02:00 AM - Task A triggers, added to queue
+02:00 AM - Task B triggers, added to queue
+02:00 AM - Task C triggers, added to queue
+
+Execution Order:
+1. Task A starts, downloads 100 posts (takes 15 minutes)
+2. Task B starts at 02:15 AM, downloads 50 posts (takes 8 minutes)
+3. Task C starts at 02:23 AM, downloads 75 posts (takes 12 minutes)
+4. All complete by 02:35 AM
+```
+
+### Scenario 2: Manual "Run Now" During Scheduled Task
+```
+02:00 AM - Task A starts (scheduled, downloading...)
+02:10 AM - User clicks "Run Now" on Task B
+02:10 AM - Task B added to queue with priority
+
+Execution Order:
+1. Task A continues running (started first)
+2. Task B waits in queue
+3. Task A completes at 02:15 AM
+4. Task B starts immediately at 02:15 AM (priority over other scheduled tasks)
+```
+
+### Scenario 3: Container Restart During Execution
+```
+02:00 AM - Task A starts downloading
+02:10 AM - Container restarts (Docker update, etc.)
+02:10 AM - Container comes back up
+02:10 AM - Task A marked as "failed" with "interrupted" message
+02:10 AM - Scheduled tasks reload, Task A will retry at next scheduled time (tomorrow 02:00 AM)
+02:10 AM - Other pending tasks start processing from queue
+```
+
+## Future Enhancements (Not in Initial Implementation)
+
+1. **Parallel Execution**: Optional setting to allow N tasks at once (requires more resources)
+2. **Smart Scheduling**: Stagger start times automatically if many tasks at same time
+3. **Queue Priorities**: User-configurable priority levels for tasks
+4. **Retry Logic**: Auto-retry failed tasks with exponential backoff
+5. **Additional Frequencies**: Weekly, custom intervals
+6. **Notification System**: Email/webhook notifications on completion/failure
+7. **Advanced Filters**: Score thresholds, content type filters
+8. **Task Templates**: Save and reuse task configurations
+9. **Execution History Page**: Dedicated page for detailed history with charts
+10. **Bulk Operations**: Enable/disable/delete multiple tasks at once
+11. **Export/Import**: Backup and restore scheduled tasks
+
+## Conclusion
+
+This implementation provides a robust scheduled downloads system with **guaranteed sequential execution**, designed specifically for Docker deployment in resource-constrained environments. The queue-based approach ensures:
+
+- ✅ Only one download at a time (no resource contention)
+- ✅ Fair task ordering (FIFO with priority support)
+- ✅ Data persistence across container restarts
+- ✅ Reliable scheduling with APScheduler
+- ✅ Proper timezone handling (user TZ -> container UTC)
+- ✅ Simple, clean UI
+- ✅ Integration with existing BDFR API
+- ✅ Smart defaults (daily schedule, time_filter="day", no_dupes=true)
+- ✅ Easy management (enable/disable/delete/run now)
+- ✅ Container-aware logging and health checks
+- ✅ Transparent queue status for users
+
+The sequential execution model is perfect for:
+- Single-user home servers
+- Docker containers with limited CPU/memory
+- Preventing Reddit API rate limits
+- Ensuring reliable, predictable downloads
+- Avoiding file system contention
+
+The system is production-ready for Docker deployment and extensible for future enhancements like parallel execution if needed.

+# BDFR API Layer
+
+The BDFR API layer provides a direct integration interface for the web interface, eliminating the need for subprocess console parsing. It wraps the existing BDFR core classes and provides a clean API with structured progress callbacks.
+
+## Overview
+
+The API layer consists of several key components:
+
+- **BDFRManager**: Main API interface class
+- **ProgressCallback**: Abstract base class for progress notifications
+- **ProgressEvent**: Structured progress event data
+- **DownloadType**: Enumeration of supported download types
+- **DownloadStatus**: Enumeration of download statuses
+
+## Quick Start
+
+### Basic Usage
+
+```python
+from bdfr.api import BDFRManager, LoggingCallback
+
+# Create a manager
+manager = BDFRManager("./downloads")
+
+# Download from a subreddit
+download_id = manager.download_subreddit(
+    "python",
+    limit=50,
+    sort="hot",
+    no_dupes=True
+)
+
+# Check status
+status = manager.get_download_status(download_id)
+print(f"Progress: {status['progress']}%")
+```
+
+### Advanced Usage with Custom Callbacks
+

+### ProgressCallback
+
+Abstract base class for implementing progress callbacks.
+
+#### Methods
+
+##### `on_progress(event: ProgressEvent)`
+
+Called when progress is made.
+
+##### `on_error(event: ProgressEvent)`
+
+Called when an error occurs.
+
+##### `on_completed(event: ProgressEvent)`
+
+Called when download is completed.
+
+### ProgressEvent
+
+Represents a progress event with structured data.
+
+#### Attributes
+
+- `event_type`: "progress", "status", "error", or "completed"
+- `download_id`: Unique identifier for the download
+- `message`: Human-readable message
+- `progress`: Progress percentage (0-100)
+- `data`: Additional structured data
+- `timestamp`: When the event occurred
+
+#### Methods
+
+##### `to_dict() -> Dict[str, Any]`
+
+Convert to dictionary for JSON serialization.
+
+### DownloadType
+
+Enumeration of supported download types:
+
+- `SUBREDDIT`: Download from subreddit
+- `USER`: Download from user
+- `MULTIREDDIT`: Download from multireddit
+- `SUBMISSIONS`: Download specific submissions
+- `ARCHIVE`: Archive only (no downloads)
+- `CLONE`: Both download and archive
+
+### DownloadStatus
+
+Enumeration of download statuses:
+
+- `QUEUED`: Download is queued but not started
+- `RUNNING`: Download is in progress
+- `COMPLETED`: Download completed successfully
+- `FAILED`: Download failed with an error
+- `CANCELLED`: Download was cancelled
+- `PAUSED`: Download is paused
+
+## Configuration
+
+The API uses the existing BDFR `Configuration` class. You can pass a custom configuration to `create_download()` or use the convenience methods with their specific parameters.
+
+### Common Configuration Options
+
+- `limit`: Maximum number of posts to process
+- `sort`: Sort method (hot, top, new, controversial, rising)
+- `time`: Time filter (all, hour, day, week, month, year)
+- `no_dupes`: Avoid duplicate downloads
+- `make_hard_links`: Create hard links for duplicates
+- `format`: Archive format (json, xml, yaml)
+
+## Web Interface Integration
+
+### FastAPI Integration Example
+
+```python
+from fastapi import FastAPI, WebSocket
+from bdfr.api import get_bdfr_manager, WebSocketCallback
+
+app = FastAPI()
+manager = get_bdfr_manager("./downloads")
+
+@app.post("/api/download/subreddit")
+async def download_subreddit(subreddit: str, limit: int = 10):
+    download_id = manager.download_subreddit(subreddit, limit=limit)
+    return {"download_id": download_id}
+
+@app.websocket("/ws/progress/{download_id}")
+async def progress_websocket(websocket: WebSocket, download_id: str):
+    await websocket.accept()
+
+    class FastAPICallback(WebSocketCallback):
+        def __init__(self):
+            super().__init__(None)
+
+        async def on_progress(self, event: ProgressEvent):
+            if event.download_id == download_id:
+                await websocket.send_json(event.to_dict())
+
+    # Add callback to existing download or create new one
+    # (Implementation depends on your specific needs)
+```
+
+### Real-time Progress Updates
+
+The API provides structured progress events that can be easily serialized to JSON for web clients:
+
+```python
+# Example progress event
+{
+    "event_type": "progress",
+    "download_id": "123e4567-e89b-12d3-a456-426614174000",
+    "message": "Downloaded submission abc123 from r/python",
+    "progress": 45.2,
+    "data": {
+        "items_processed": 12,
+        "items_found": 25,
+        "current_item": "abc123",
+        "phase": "downloading_submission"
+    },
+    "timestamp": "2023-12-07T10:30:45.123456"
+}
+```
+
+## Error Handling
+
+The API provides comprehensive error handling:
+
+- **Download errors**: Network issues, authentication problems, etc.
+- **Configuration errors**: Invalid parameters, missing files, etc.
+- **System errors**: Disk space, permissions, etc.
+
+All errors are captured and reported through the progress callback system with detailed error information.
+
+## Threading and Concurrency
+
+The API is designed to be thread-safe and supports concurrent downloads:
+
+- Each download runs in its own thread
+- Progress callbacks are async-safe
+- Multiple downloads can run simultaneously
+- Thread-safe status tracking
+
+## Logging
+
+The API integrates with Python's logging system:
+
+```python
+import logging
+
+# Configure logging
+logging.basicConfig(level=logging.INFO)
+
+# Use LoggingCallback for automatic log output
+callbacks = [LoggingCallback("my_app")]
+```
+
+## Examples
+
+See `bdfr/examples/api_usage.py` for comprehensive examples including:
+
+- Basic usage
+- Custom callbacks
+- Web integration
+- Error handling
+- User downloads
+- Archive operations
+
+## Migration from Subprocess
+
+### Before (Subprocess)
+
+```python
+import subprocess
+import json
+
+# Start BDFR via subprocess
+proc = subprocess.Popen([
+    "python", "-m", "bdfr", "download",
+    "--subreddit", "python",
+    "--limit", "50",
+    "./downloads"
+], stdout=subprocess.PIPE, stderr=subprocess.PIPE)
+
+# Parse console output for progress
+while True:
+    line = proc.stdout.readline().decode().strip()
+    if not line:
+        break
+    # Parse progress from console output...
+```
+
+### After (API)
+
+```python
+from bdfr.api import BDFRManager, LoggingCallback
+
+# Use API directly
+manager = BDFRManager("./downloads")
+download_id = manager.download_subreddit("python", limit=50)
+
+# Get structured progress updates
+status = manager.get_download_status(download_id)
+print(f"Progress: {status['progress']}%")
+```
+
+## Benefits
+
+1. **No subprocess overhead**: Direct integration with BDFR core
+2. **Structured progress**: Rich progress events instead of console parsing
+3. **Better error handling**: Detailed error information and stack traces
+4. **Thread-safe**: Concurrent downloads with proper synchronization
+5. **Web-friendly**: JSON-serializable progress events
+6. **Extensible**: Custom progress callbacks for different integrations
+7. **Maintainable**: Clean separation of concerns
+
+## Requirements
+
+- Python 3.7+
+- Existing BDFR installation
+- Dependencies: `praw`, `requests`, and other BDFR dependencies
+
+## Installation
+
+The API layer is included with BDFR and requires no additional installation. Simply import and use:

+# BDFR Web Interface
+
+A complete web-based interface for the Bulk Downloader for Reddit (BDFR) with real-time progress tracking and scheduled downloads.
+
+This tool is a frontend for the BDFR tool found here: https://github.com/Serene-Arc/bulk-downloader-for-reddit
+Although I've made a few changes to allow for better repeat download persistence to avoid redownloading previously downloaded content.
+
+## Features
+
+### 🎯 **Three Download Modes**
+- **Download**: Media files only (images, videos, gifs) from Reddit posts
+- **Archive**: Post metadata (title, author, comments) in JSON/XML format
+- **Clone**: Complete backup combining media files and metadata
+
+### 📍 **Multiple Source Types**
+- **Subreddit Downloads**: Download content from any subreddit with customizable filters
+- **User Downloads**: Download posts from specific users (submitted, upvoted, or saved content)
+
+### ⚡ **Real-Time Progress Tracking**
+- WebSocket-based live progress updates
+- Visual progress bars and status indicators
+- Download queue management with cancel functionality
+- Phase tracking (downloading, processing, completing)
+
+### 🔐 **Reddit OAuth2 Authentication**
+- Secure authentication with Reddit API
+- Access to private content (saved/upvoted posts)
+- Session management and token refresh
+
+### ⚙️ **Advanced Options**
+- **Duplicate Detection**: Avoid re-downloading existing files
+- **Hard Link Creation**: Save disk space with file links
+- **Scheduled Downloads**: Set up daily automatic downloads
+- **Content Filtering**: Filter by score, time range, and sort order
+- **Simple Check**: Fast URL-based duplicate detection
+
+### 📊 **Management Dashboard**
+- Active download monitoring
+- Scheduled task management
+- System status indicators
+- Download history and statistics
+
+## Quick Start with Docker Compose
+
+```yaml
+version: '3.8'
+services:
+  bdfr-web:
+    image: moderatewinguy/bdfr-web:latest
+    # Uncomment and set user if needed (optional for most setups)
+    # user: "1000:1000"  # Set to your user's UID:GID (run 'id' to find yours)
+    ports:
+      - "8000:8000"
+    volumes:
+      - ./downloads:/app/downloads  # Reddit content storage
+      - ./data:/app/data            # Database persistence
+    environment:
+      - BDFR_CLIENT_ID=your_reddit_client_id
+      - BDFR_CLIENT_SECRET=your_reddit_client_secret
+      - BDFR_REDIRECT_URI=http://localhost:8000/auth/callback
+```
+
+Run with:
+```bash
+docker-compose up -d
+```
+
+Access at: http://localhost:8000
+
+## Configuration
+
+### User Permissions
+
+The container is designed to run as any user, allowing it to match your system's permissions.
+
+**For TrueNAS/NAS Systems:**
+- Use the "Custom User" setting in your container configuration
+- Set it to the UID of the user that owns your mounted shares
+- The container will automatically run as that user
+
+**For Docker Compose:**
+If needed, uncomment the `user:` line in docker-compose.yml:
+```yaml
+user: "1000:1000"  # Set to your user's UID:GID
+```
+
+Find your UID/GID with: `id` (Linux/Mac) or `wsl id` (Windows WSL)
+
+**The container will work with any UID/GID** - just ensure the mounted volumes are owned by the same user.
+
+### Environment Variables
+
+| Variable | Description | Required |
+|----------|-------------|----------|
+| `BDFR_CLIENT_ID` | Reddit OAuth2 client ID | Yes |
+| `BDFR_CLIENT_SECRET` | Reddit OAuth2 client secret | Yes |
+| `BDFR_REDIRECT_URI` | OAuth2 redirect URI | Yes |
+| `HOST` | Server host (default: 0.0.0.0) | No |
+| `PORT` | Server port (default: 8000) | No |
+| `DEBUG` | Enable debug mode | No |
+
+## Volume Mounts
+
+- **`/app/downloads`**: All Reddit content is stored here
+- **`/app/data`**: SQLite databases for scheduled tasks and application data
+
+## API Endpoints
+
+- `GET /` - Web interface
+- `POST /api/download/subreddit` - Start subreddit download
+- `POST /api/download/user` - Start user download
+- `GET /api/downloads` - List active downloads
+- `DELETE /api/downloads/{id}` - Cancel download
+- `GET /health` - Health check
+- `WS /ws/progress` - Real-time progress updates
+
+## Getting Reddit OAuth Credentials
+
+1. Go to https://www.reddit.com/prefs/apps
+2. Click "Create App" or "Create Another App"
+3. Select "web app" and fill in the details
+4. Set redirect URI to: `http://localhost:8000/auth/callback`
+5. Copy the client ID and client secret to your `.env` file
+
+## Use Cases
+
+- **Content Archiving**: Save Reddit posts and media for offline access
+- **Research Data Collection**: Gather post metadata for analysis
+- **Media Backup**: Download images/videos from favorite subreddits
+- **Automated Downloads**: Schedule daily content collection
+- **Personal Archive**: Backup your own posts and saved content
+
+## Supported Content Sources
+
+- Direct image/video links
+- Imgur albums and images
+- Reddit native media (images, videos, gifs)
+- YouTube videos
+- Gfycat animations
+- And many more via yt-dlp fallback
+
+## Technical Details
+
+- **Base Image**: Python 3.11-slim
+- **Web Framework**: FastAPI with WebSocket support
+- **Frontend**: Vanilla JavaScript with modern CSS
+- **Database**: SQLite for task scheduling
+- **Authentication**: OAuth2 with Reddit API
+- **File Processing**: Multi-threaded downloads with progress tracking
+
+

+
+**Note**: This image includes the complete BDFR tool, so you can also run CLI commands directly:
+```bash
+docker exec bdfr-web bdfr download /app/downloads --subreddit python -L 50

+web_interface/
+├── app/
+│   └── main.py              # FastAPI application
+├── static/
+│   ├── css/
+│   │   └── style.css        # Modern CSS styling
+│   └── js/
+│       └── app.js           # WebSocket client and form handling
+├── templates/
+│   └── index.html           # Main web interface
+└── requirements.txt         # Python dependencies
+```
+
+## Installation

+   ```bash
+   cd web_interface
+   pip install -r requirements.txt
+   ```
+
+2. **Run the Application**:
+   ```bash
+   cd app
+   python main.py
+   ```
+
+3. **Access the Interface**:
+   Open your browser and navigate to `http://localhost:8000`
+
+## API Endpoints
+
+### Download Endpoints
+- `POST /api/download/subreddit` - Start subreddit download
+- `POST /api/download/user` - Start user download
+- `GET /api/downloads` - List all active downloads
+- `GET /api/downloads/{download_id}` - Get specific download status
+- `DELETE /api/downloads/{download_id}` - Cancel download
+
+### WebSocket
+- `ws://localhost:8000/ws/progress` - Real-time progress updates
+
+### Status Endpoints
+- `GET /` - Main web interface
+- `GET /health` - Health check
+- `GET /api/bdfr/status` - BDFR system status
+
+## Configuration
+
+The application uses the following default settings:
+- **Host**: `0.0.0.0`
+- **Port**: `8000`
+- **WebSocket Path**: `/ws/progress`
+- **Static Files**: Served from `/static`
+
+## Docker Support
+
+To run with Docker:
+
+```bash
+# Build the image
+docker build -t bdfr-web-interface .
+
+# Run the container
+docker run -p 8000:8000 bdfr-web-interface
+```
+
+## Development
+
+### Adding New Features
+
+1. **Backend Changes**: Modify `app/main.py` to add new endpoints
+2. **Frontend Changes**: Update `templates/index.html` for UI changes
+3. **Styling**: Modify `static/css/style.css` for visual changes
+4. **JavaScript**: Update `static/js/app.js` for client-side functionality
+
+### WebSocket Integration
+
+The WebSocket connection automatically handles:
+- Connection establishment and reconnection
+- Progress updates from the server
+- Error handling and user notifications
+- Real-time UI updates
+
+### Form Handling
+
+Both download forms include:
+- Input validation
+- Loading states
+- Success/error notifications
+- Automatic form reset on success
+
+## Integration with BDFR
+
+### Direct BDFR API Integration
+
+This interface uses the direct BDFR API integration, eliminating the need for subprocess console parsing:
+
+- `/api/download/subreddit` - Downloads from subreddits using `BDFRManager.download_subreddit()`
+- `/api/download/user` - Downloads from users using `BDFRManager.download_user()`
+- `/api/bdfr/status` - Returns BDFR system status and capabilities
+- `/ws/progress` - Provides real-time progress updates via WebSocket
+
+The web interface imports `BDFRManager` directly from `bdfr.api` and uses structured progress callbacks for seamless integration.
+
+### Migration Notes
+
+**Previous Approach (Subprocess-based)**:
+- Used `subprocess.Popen` to start BDFR CLI
+- Parsed console output with regex for progress updates
+- Required `BDFRRunner` class for process management
+- Used `threading.Thread` and `queue.Queue` for coordination
+
+**Current Approach (Direct API)**:
+- Direct integration with `BDFRManager` from `bdfr.api`
+- Structured `ProgressEvent` callbacks instead of console parsing
+- Thread-safe progress tracking with `ProgressCallback` interface
+- No subprocess overhead or console output parsing required
+
+The migration provides better error handling, structured progress events, and eliminates console parsing complexity.
+
+## Browser Support
+
+- Modern browsers with WebSocket support
+- Chrome 60+
+- Firefox 55+
+- Safari 11+
+- Edge 79+
+
+## Security Considerations
+
+- CORS is enabled for all origins (configure for production)
+- Input validation on both client and server
+- No authentication implemented (add as needed)
+- WebSocket connections are not secured (use WSS in production)
+
+## Production Deployment
+
+For production deployment:
+
+1. Configure CORS for specific origins
+2. Add authentication/authorization
+3. Use HTTPS/WSS for secure connections
+4. Configure proper logging
+5. Set up reverse proxy (nginx recommended)
+6. Add rate limiting
+7. Configure environment variables
+
+## Troubleshooting
+
+### Common Issues
+
+1. **WebSocket Connection Failed**:
+   - Check if the server is running
+   - Verify firewall settings
+   - Check browser console for errors
+
+2. **Downloads Not Starting**:
+   - Verify BDFR integration is configured
+   - Check server logs for errors
+   - Ensure form data is valid
+
+3. **Static Files Not Loading**:
+   - Verify static file paths
+   - Check file permissions
+   - Ensure proper MIME types
+
+### Debug Mode
+
+Run with debug logging:
+```bash
+python main.py --log-level debug
+```

+# Scheduled Downloads Feature
+
+## Overview
+
+The BDFR Web Interface now supports scheduled downloads, allowing users to configure downloads that run automatically on a daily basis. This feature is designed to work seamlessly in Docker containers and ensures sequential execution to prevent system overload.
+
+## Features
+
+### 1. **Daily Scheduling**
+- Tasks run once per day at a user-specified time
+- Time is specified in the user's local timezone and automatically converted to UTC for container execution
+- Automatically sets `time_filter="day"` to only download content from the last 24 hours
+- Always enables `no_dupes=True` to avoid re-downloading existing content
+
+### 2. **Sequential Execution**
+- Tasks are processed one at a time through a queue system
+- Manual "Run Now" tasks have priority over scheduled tasks
+- Queue status is displayed in real-time
+
+### 3. **Persistent Storage**
+- SQLite database stores task configurations
+- APScheduler job store ensures tasks persist across container restarts
+- Execution history tracked for each task
+
+### 4. **Full Task Management**
+- Create, enable/disable, and delete scheduled tasks
+- Run tasks manually on-demand
+- View last run and next scheduled run times
+
+## Architecture
+
+### Backend Components
+
+#### 1. **Database Models** (`web_interface/app/models.py`)
+- `ScheduledTask`: Stores task configuration
+  - Fields: name, source (subreddit/user), schedule, timezone, etc.
+  - Automatically sets time_filter="day" and no_dupes=True
+- `TaskExecutionHistory`: Tracks each execution
+  - Fields: task_id, status, items downloaded, errors, etc.
+
+#### 2. **Task Queue** (`web_interface/app/task_queue.py`)
+- `TaskQueue` class manages sequential execution
+- Priority queue: 0=scheduled, 1=manual
+- Blocks until each download completes before starting the next
+- Thread-safe using asyncio
+
+#### 3. **Scheduler Service** (`web_interface/app/scheduler.py`)
+- APScheduler with SQLAlchemy job store for persistence
+- Functions:
+  - `schedule_task()`: Creates cron job
+  - `queue_scheduled_task()`: Adds task to queue (called by scheduler)
+  - `execute_scheduled_task()`: Executes download and waits for completion
+  - `wait_for_download_completion()`: Polls every 5 seconds until done
+
+#### 4. **API Endpoints** (`web_interface/app/scheduled_tasks.py`)
+```
+POST   /api/scheduled-tasks          - Create task
+GET    /api/scheduled-tasks          - List all tasks
+GET    /api/scheduled-tasks/{id}     - Get specific task
+PUT    /api/scheduled-tasks/{id}     - Update task
+DELETE /api/scheduled-tasks/{id}     - Delete task
+POST   /api/scheduled-tasks/{id}/toggle - Enable/disable
+POST   /api/scheduled-tasks/{id}/run-now - Queue immediately
+GET    /api/scheduled-tasks/{id}/history - Execution history
+GET    /api/scheduled-tasks/queue/status - Queue status
+```
+
+### Frontend Components
+
+#### 1. **HTML** (`web_interface/templates/index.html`)
+- "Run Daily" checkbox in Advanced Options
+- Schedule configuration fields (task name, run time)
+- Scheduled Downloads section with task cards
+- Queue status badge
+
+#### 2. **JavaScript** (`web_interface/static/js/app.js`)
+- `loadScheduledTasks()`: Fetches and renders tasks
+- `createScheduledTask()`: Creates new scheduled task
+- `toggleTask()`, `deleteTask()`, `runTaskNow()`: Task management
+- `updateQueueStatus()`: Polls queue every 10 seconds
+- Auto-detects browser timezone via `Intl.DateTimeFormat()`
+
+#### 3. **CSS** (`web_interface/static/css/style.css`)
+- Task card styling with hover effects
+- Status badges (enabled/disabled)
+- Schedule options panel
+- Queue status badge
+
+## Usage Guide
+
+### Creating a Scheduled Download
+
+1. **Configure Download Settings**
+   - Select download mode (Download/Archive/Clone)
+   - Choose source type (Subreddit/User)
+   - Enter source name
+   - Set limit, sort, and other options
+
+2. **Enable Scheduling**
+   - Check "Run Daily" in Advanced Options
+   - Enter a task name (e.g., "Daily Python Posts")
+   - Select run time (24-hour format, in your local timezone)
+
+3. **Submit**
+   - Click "Start Download" to create the scheduled task
+   - Task appears in the Scheduled Downloads section
+   - First run scheduled for the specified time
+
+### Managing Scheduled Tasks
+
+Each task card shows:
+- Task name and source
+- Download mode
+- Schedule (daily at X time)
+- Last run and next run times
+- Status (Enabled/Disabled)
+
+**Actions:**
+- **Disable/Enable**: Toggle task on/off without deleting
+- **Run Now**: Add task to queue immediately (higher priority)
+- **Delete**: Remove task permanently
+
+### Queue System
+
+- Queue status badge shows number of tasks waiting
+- Tasks execute one at a time to prevent overload
+- Manual "Run Now" tasks have priority over scheduled tasks
+- Download progress appears in Progress section
+
+## Docker Deployment
+
+### Volume Mounts Required
+
+```yaml
+volumes:
+  - ./downloads:/downloads          # Downloaded files
+  - ./data:/app/data                # Database and job store
+```
+
+### Database Location
+- SQLite: `/app/data/scheduled_tasks.db`
+- APScheduler job store: Same database
+
+### Timezone Handling
+- User specifies time in their local timezone
+- Frontend auto-detects timezone via JavaScript
+- Backend converts to UTC for container execution
+- Cron jobs run at correct local time regardless of container timezone
+
+## Technical Details
+
+### Sequential Execution Flow
+
+1. APScheduler triggers at scheduled time
+2. Scheduler calls `queue_scheduled_task(task_id)`
+3. Task added to queue with priority 0
+4. Queue worker picks up task
+5. `execute_scheduled_task()` called
+6. Downloads via existing BDFR API
+7. `wait_for_download_completion()` polls every 5s
+8. Once complete, queue processes next task
+9. Execution history recorded
+
+### Time Filter Logic
+
+For scheduled tasks:
+- `time_filter` is automatically set to "day"
+- This filters Reddit API to only return posts from last 24 hours
+- Combined with daily scheduling, ensures only new content downloaded
+- Prevents re-downloading old content
+
+### Duplicate Prevention
+
+For scheduled tasks:
+- `no_dupes` is automatically enabled
+- Uses existing BDFR duplicate detection
+- Checks file hashes or URLs (depending on simple_check setting)
+- Skips files that already exist
+
+## Testing Checklist

+# BDFR Web Interface Startup Scripts
+
+This directory contains simple startup scripts to easily run the BDFR web interface application.
+
+## Available Scripts
+
+### 🚀 Quick Start
+
+Choose the appropriate script for your operating system:
+
+- **`start.py`** - Cross-platform Python script (recommended)
+- **`start.sh`** - Unix/Linux/macOS shell script
+- **`start.bat`** - Windows batch script
+
+## Usage
+
+### Option 1: Python Script (Cross-platform)
+
+```bash
+# Navigate to the web_interface directory
+cd web_interface
+
+# Run the startup script
+python start.py
+```
+
+### Option 2: Shell Script (Unix/Linux/macOS)
+
+```bash
+# Navigate to the web_interface directory
+cd web_interface
+
+# Make sure the script is executable
+chmod +x start.sh
+
+# Run the startup script
+./start.sh
+```
+
+### Option 3: Batch Script (Windows)
+
+```cmd
+REM Navigate to the web_interface directory
+cd web_interface
+
+REM Run the startup script
+start.bat
+```
+
+## What the Scripts Do
+
+1. **Check Python version** - Ensures Python 3.8+ is installed
+2. **Install dependencies** - Automatically installs required packages from `requirements.txt`
+3. **Verify BDFR module** - Checks if the BDFR module is available
+4. **Start the server** - Launches the FastAPI application with uvicorn
+
+## Server Information
+
+Once started, the web interface will be available at:
+- **Main interface**: http://localhost:8000
+- **API documentation**: http://localhost:8000/docs
+- **Health check**: http://localhost:8000/health
+
+## Features
+
+- ✅ Automatic dependency management
+- ✅ Cross-platform compatibility
+- ✅ Colored output for better user experience
+- ✅ Error handling and informative messages
+- ✅ Graceful server shutdown
+- ✅ BDFR module availability checking
+
+## Requirements
+
+- Python 3.8 or higher
+- Internet connection (for installing dependencies)
+- BDFR module in Python path (parent directory should contain the BDFR package)
+- Reddit OAuth application (for authentication features)
+
+## Reddit OAuth Setup
+
+To use the authentication features, you need to:
+
+1. **Create a Reddit OAuth Application**:
+   - Go to [Reddit App Preferences](https://www.reddit.com/prefs/apps)
+   - Click "Create App" or "Create Another App"
+   - Choose "web app" as the application type
+   - Set a name (e.g., "BDFR Web Interface")
+   - Set redirect URI to: `http://localhost:8000/auth/callback`
+
+2. **Configure the Redirect URI** (if using a different port or domain):
+   - Run the OAuth setup helper: `python setup_oauth.py`
+   - Or manually copy `.env.example` to `.env`
+   - Update the following in the `.env` file:
+     - `BDFR_REDIRECT_URI` - Your OAuth redirect URI
+     - `BDFR_CLIENT_ID` - Your OAuth client ID (from Reddit app)
+     - `BDFR_CLIENT_SECRET` - Your OAuth client secret (from Reddit app)
+   - Make sure the redirect URI matches exactly what you set in your Reddit OAuth app
+
+3. **Update BDFR Configuration**:
+   - The web interface uses the same OAuth credentials as BDFR
+   - You need to either update your existing Reddit OAuth app or create a new one
+
+## Option A: Update Existing Reddit OAuth App
+
+If you want to use the same OAuth app for both BDFR CLI and web interface:
+
+1. Go to [Reddit App Preferences](https://www.reddit.com/prefs/apps)
+2. Find your existing app (the one with client ID `U-6gk4ZCh3IeNQ`)
+3. Click "edit" and add your redirect URI to the "redirect uris" field:
+   - `http://localhost:8000/auth/callback`
+4. Save the changes
+
+## Option B: Create a New Reddit OAuth App (Recommended)
+
+For better separation between CLI and web interface:
+
+1. Go to [Reddit App Preferences](https://www.reddit.com/prefs/apps)
+2. Click "Create App" or "Create Another App"
+3. Fill in the details:
+   - **Name**: `BDFR Web Interface` (or your preferred name)
+   - **App type**: `web app`
+   - **Description**: `Web interface for BDFR (Bulk Downloader for Reddit)`
+   - **About URL**: (optional)
+   - **Redirect URI**: `http://localhost:8000/auth/callback`
+4. Click "Create app"
+5. Copy the client ID and client secret
+6. Update `bdfr/default_config.cfg` with the new credentials:
+   ```
+   client_id = YOUR_NEW_CLIENT_ID
+   client_secret = YOUR_NEW_CLIENT_SECRET
+   ```
+
+## Troubleshooting
+
+### "BDFR module not found"
+Make sure you're running the script from the correct directory, or ensure the parent directory containing the BDFR package is in your Python path.
+
+### "Python 3.8+ required"
+Install Python 3.8 or higher from the official Python website.
+
+### "Permission denied" (Unix/Linux/macOS)
+Make sure the shell script has execute permissions:
+```bash
+chmod +x start.sh
+```
+
+### "invalid redirect_uri parameter" (OAuth Error)
+This error occurs when the redirect URI doesn't match what you configured in your Reddit OAuth app:
+
+1. **Verify your Reddit OAuth app settings**:
+   - Go to [Reddit App Preferences](https://www.reddit.com/prefs/apps)
+   - Find your app and check the redirect URI
+   - Make sure it exactly matches what you're using
+
+2. **Update the redirect URI**:
+   - Copy `.env.example` to `.env`
+   - Set `BDFR_REDIRECT_URI` to match your Reddit OAuth app
+   - Example: `BDFR_REDIRECT_URI=http://localhost:8000/auth/callback`
+
+3. **Common redirect URI formats**:
+   - Local development: `http://localhost:8000/auth/callback`
+   - With custom port: `http://localhost:3000/auth/callback`
+   - Production: `https://yourdomain.com/auth/callback`
+
+4. **Recreate your OAuth app if needed**:
+   - Delete the existing app in Reddit
+   - Create a new one with the correct redirect URI
+
+## Manual Alternative
+
+If you prefer to run the server manually:
+
+```bash
+cd web_interface
+pip install -r requirements.txt
+python -m uvicorn app.main:app --host 0.0.0.0 --port 8000 --reload
