:zap: The most efficient way to experiment with WebAssembly to date. No need to learn C/C++ or Rust, hand roll your wasm modules and use them within minutes with familiar JavaScript-like syntax!
This loader is for Walt, an alternative syntax for wasm. Allowing you
to write JavaScript-like .walt
scripts and import the compiled wasm binary directly into
your JS Application.
npm install --save-dev walt-compiler walt-loader
The loader user wasm-loader under the hood and has the same API. Resolving to a factory function which returns a promise for the WebAssembly module.
Make sure you have a working Webpack config and that the walt-compiler
package is
installed and ready to use. Then update your wepback config:
Resolve the .walt
file extensions
resolve: {
extensions: [".walt"]
}
and append the walt-loader
to loaders config option
module: {
loaders: {
{
test: /\.walt$/,
loader: "walt-loader"
}
}
}
Fire up your favorite editor and create a simple .walt
Module file. Here is a
counter module example:
counter.walt:
let counter: i32 = 0;
export function decrement(): i32 {
counter -= 1;
return counter;
}
export function increment(): i32 {
counter += 1;
return counter;
}
Once you have your module written, then you can import it into your existing JavaScript Application.
example.js:
import makeCounter from './walt/counter';
makeCounter().then(wasmModule => {
console.log(wasmModule.instance.exports.increment()); // 1
console.log(wasmModule.instance.exports.increment()); // 2
console.log(wasmModule.instance.exports.decrement()); // 1
});
That's it. You can now write your wasm binaries and import them directly into your Webpack App!
