# Laracasts Downloader A robust Go application that downloads Laracasts topics, series and bits. This tool helps you organize and manage your Laracasts content offline for convenient access and learning. #### Note: This project is still in beta mode, not fully implemented yet it downloads all topics, series and bits from Laracasts. ## Features ### Topic-Based Organization - Automatically organizes downloads by topics (e.g., Laravel, Vue, Testing, etc.) - Creates a clean directory structure for easy navigation - Generates summary files for each topic and an overall download summary - Maintains metadata for all downloaded content ### Concurrent Downloads - Uses worker pools for efficient parallel downloading - Handles multiple topics and series simultaneously - Implements rate limiting to prevent server overload - Optimizes bandwidth usage with configurable concurrency ### Smart Error Handling - Retries failed downloads with exponential backoff - Maintains download state to resume interrupted operations - Creates detailed logs of successes and failures - Validates downloaded files for integrity ### Progress Tracking - Shows real-time download progress with ETA - Provides detailed statistics for each topic and series - Creates summary files with download status and metadata - Displays bandwidth usage and download speeds ## Directory Structure ```auto downloads/ ├── topics/ │ ├── Laravel/ │ │ ├── Laravel Basics/ │ │ │ ├── 01-Introduction-to-Laravel.mp4 │ │ │ ├── 02-Routing-Basics.mp4 │ │ │ └── series-info.json │ │ └── Advanced Laravel/ │ │ ├── 01-Service-Containers.mp4 │ │ └── series-info.json │ ├── Vue/ │ │ └── Vue3-Essentials/ │ │ ├── 01-Getting-Started.mp4 │ │ └── series-info.json │ └── Testing/ │ └── PHPUnit-Testing/ │ ├── 01-Introduction.mp4 │ └── series-info.json └── .cache/ ├── downloads/ │ └── download-state.json ├── series/ │ └── series-metadata.json └── state/ └── app-state.json ``` ## Installation 1. Ensure you have Go 1.18 or higher installed: `go version` 1. Install ffmpeg (required for video processing): ```auto # Ubuntu/Debian sudo apt-get install ffmpeg # macOS brew install ffmpeg # Windows choco install ffmpeg ``` 1. Clone the repository: ```auto git clone https://github.com/sajjadanwar0/laracasts-downloader.git cd laracasts-downloader ``` 1. Install dependencies: `go mod download` ## Configuration 1. Copy the example environment file: `cp .env.example .env` 1. Configure your environment variables in .env: ```auto EMAIL=your@email.com PASSWORD=your_password DOWNLOAD_PATH=/path/to/downloads VIDEO_QUALITY=1080p # Options: 360p, 540p, 720p, 1080p CONCURRENT_DOWNLOADS=3 RETRY_ATTEMPTS=3 BUFFER_SIZE=8192 ``` ## Usage ### Basic Usage Run the downloader to fetch all available content: `go run main.go` The application will: 1. Log in to your Laracasts account 2. Fetch all available topics 3. Create topic directories 4. Download all series for each topic 5. Generate summary files ### Download Specific Series To download a specific series, use the series flag with the slug: `go run main.go -s the-definition-series` ### Download All Topics To download all topics: `go run main.go` ## Environment Variables | Variable | Description | Required | Default | | --- | --- | --- | --- | | EMAIL | Laracasts account email | Yes | - | | PASSWORD | Laracasts account password | Yes | - | | DOWNLOAD\_PATH | Download directory path | Yes | - | | VIDEO\_QUALITY | Preferred video quality | No | 1080p | | CONCURRENT\_DOWNLOADS | Number of parallel downloads | No | 3 | | RETRY\_ATTEMPTS | Number of download retry attempts | No | 3 | | BUFFER\_SIZE | Download buffer size in bytes | No | 8192 | ## Performance Optimization The downloader implements several performance optimization strategies: ### Buffered Downloads - Uses buffered I/O for efficient file operations - Implements configurable buffer sizes - Minimizes system calls during downloads ### Concurrent Processing - Parallel processing of topics and series - Worker pools for download management - Rate limiting to prevent overload ### Memory Management - Efficient memory usage with buffer pools - Garbage collection optimization - Memory-conscious file handling ### State Management - Persistent download state - Resume capability for interrupted downloads - Efficient metadata caching ## Error Handling The application implements comprehensive error handling: - **Download Retry** : Automatically retries failed downloads with exponential backoff - **State Recovery** : Maintains download state for recovery after interruptions - **Validation** : Checks file integrity after download - **Logging** : Creates detailed logs for debugging and troubleshooting - **Error Classification** : Categorizes errors for appropriate handling: - Network errors - Authentication failures - File system errors - Rate limiting issues ## Contributing Contributions are welcome!
