Building a Real-Time WebSocket-Based Chat Server with Rust and WASM
The article provides a tutorial on building a real-time chat server using Rust and WebAssembly. It outlines the necessary components for creating a scalable system, including backend and frontend technologies. Key features include message persistence, basic authentication, and strategies for testing.
- ▪The chat server utilizes Rust for the backend and WebSocket for real-time communication.
- ▪Messages are persisted in a database, allowing for message history retrieval.
- ▪The tutorial covers system design, backend implementation, and deployment considerations.
