Canvas

The public-facing content delivery service for the Sharify platform.

Canvas works alongside other Sharify components:

• Zephyr: Core upload API and storage service
• Spine: Web panel backend for user/content management
• Sharify-Go: Go SDK for programmatic uploads
• Sharify-Desktop: Cross-platform desktop app

Note: This project is not actively maintained and should not be used in a production environment.

What it does

Canvas takes a hostname + path combination and converts it into a storage key to fetch content. So when someone visits username.example.com/abc123, Canvas hashes it and retrieves the actual content from Redis or R2. It supports redirects, images, files, and pastes.

Key Features

• Multi-tier storage (Redis + Cloudflare R2)
• Automatic content type detection
• Custom domain support
• Syntax-highlighted paste viewer
• Basic security with path sanitization and rate limiting

API Endpoints

• GET / - Just returns OK (health check)
• GET /p - Simple paste creation frontend interface
• GET /:secret - The main content retrieval endpoint
