Project Overview
The Get Link Backend is a high-performance Go (Golang)-based server designed to support real-time, secure link and file sharing across mobile and desktop devices. Built using Gorilla Mux, PostgreSQL, Redis, and WebSockets, the backend powers the Get Link Chrome Extension and Android App, providing seamless integration with WhatsApp and Telegram for cross-platform communication. This RESTful API service facilitates real-time link syncing, file transfers, and instant messaging between devices. WebSocket support ensures low-latency updates for connected clients, while Redis handles fast in-memory data operations and session management. With robust security, structured logging via Zap, and token-based JWT authentication, the backend is optimized for performance, security, and scalability. The backend is structured to handle a variety of routes including file upload/download, link management, real-time socket connections, and third-party messaging service integrations.
