Building Real-Time Web Applications with Rust WebSocket: Server and Client Examples

Introduction:

WebSocket, a powerful communication protocol, has revolutionized real-time web applications by enabling bidirectional communication between clients and servers. In this article, we will explore how to implement WebSocket in Rust, a modern and performance-focused programming language. We will provide server-side and client-side examples to help you grasp the concept and build your own real-time applications.

Server-Side Implementation

1. Setting Up the Rust Project

To get started with WebSocket on the server side, create a new Rust project using Cargo, Rust’s package manager. Use the following command:

cargo new rust_websocket_server

2. Adding Dependencies

Modify the Cargo.toml file to include the tokio and websocket libraries:

[dependencies]
tokio = { version = "1", features = ["full"] }
websocket = "0.24"

3. Creating a WebSocket Server

Implement a WebSocket server by defining routes and handling WebSocket connections in your Rust code. Here’s a simplified example:

use tokio::net::TcpListener;
use websocket::{accept…
