Bundle.js

WebAssembly First-Class Support

August 26, 2025 By the Dev Team

We're excited to announce that Bundle.js now provides native support for WebAssembly! This means you can import and use WASM modules directly in your JavaScript projects with no external tooling.

Key Features

  • Native WebAssembly integration with module auto-detection
  • Zero-config SIMD and threads support for optimized execution
  • Automatic Emscripten compatibility layer for legacy projects
wasm/add.wasm

// Rust implementation using wasm-bindgen:
#[wasm_bindgen]
pub fn add(a: i32, b: i32) -> i32 {
    a + b
}
JavaScript usage

import add from './add.wasm';

const result = await add(2, 3);
console.log(result); // 5
