Rust WebAssembly can significantly improve React application performance. Here’s how to integrate it.

Setup

cargo install wasm-pack
wasm-pack build --target web

Rust Code

use wasm_bindgen::prelude::*;

#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
    a + b
}

React Integration

import init, { add } from './pkg/rust_wasm.js';

async function loadWasm() {
    await init();
    console.log(add(2, 3)); // 5
}

Performance Benefits

  • Faster computation for heavy operations
  • Memory efficient
  • Type safe
  • Near-native performance

Best Practices

  1. Use for CPU-intensive tasks
  2. Minimize data transfer
  3. Profile performance
  4. Handle errors properly
  5. Bundle efficiently

Conclusion

Boost React performance with Rust WebAssembly! ⚡
