Walt Alternative WebAssembly Syntax Loader for Webpack
⚡️ 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.
Install
npm install --save-dev walt-compiler walt-loader
Usage
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.
With Webpack
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"
Importing Walt Modules directly
Fire up your favorite editor and create a simple .walt
Module file. Here is a
counter module example:
counter.walt:
let counter: i32 = 0; : i32 { counter -= 1; return counter;} : i32 { counter += 1; return counter;}
Once you have your module written, then you can import it into your existing JavaScript Application.
example.js:
; ;
That's it. You can now write your wasm binaries and import them directly into your Webpack App!
