Clients

cat-web-programming::http-client

Make HTTP network requests.

The following table outlines common tasks for building web clients in Rust and relevant crates. Web clients can range from simple HTTP request libraries to more advanced tools for interacting with APIs or building web applications that fetch data.

  • Simple HTTP Requests: ureq⮳ is often recommended for its simplicity, especially for basic use cases.
  • General-Purpose HTTP Client: reqwest⮳ is highly versatile and supports a wide range of features.
  • Performance-Focused HTTP Client: isahc⮳ is often considered to be performant.
  • REST API Interaction: reqwest⮳ + serde⮳.
  • When working with WASM, you'll either use reqwest⮳ compiled to WASM or interact with the browser's 'fetch' API via wasm-bindgen⮳.
TopicRust Crates (Examples)Notes
HTTP Clients (Making Requests)reqwest⮳, isahc⮳, ureq⮳reqwest⮳ is a popular and versatile HTTP client. isahc⮳ is another option with a focus on performance. ureq⮳ is a lightweight and easy-to-use HTTP client.

Most HTTP client crates support asynchronous requests using async and await⮳. Asynchronous requests are generally preferred for web clients to avoid blocking the main thread.

API Interaction (REST)(Uses HTTP clients and serialization crates)Interacting with REST APIs usually involves making HTTP requests using crates like reqwest⮳ and handling JSON responses with serde⮳.

WebAssembly (WASM) Clients (Fetching Data)(Often uses reqwest⮳ or fetch⮳ API via wasm-bindgen⮳)In WASM contexts, you can either use reqwest⮳ (compiled to WASM) or interact directly with the browser's fetch⮳ API using wasm-bindgen⮳.
Browser Interaction (WASM)wasm-bindgen⮳wasm-bindgen⮳ is essential for interacting with browser APIs from Rust/WASM, including making network requests.
