Releases

Please check releases for stable versions. The develop branch contains latest development changes that might be unstable.

Usage

Prepare your WAT file (add.wat)

(module
  ;; Addition
  (func $add (param $a i32) (param $b i32) (result i32)
    local.get $a
    local.get $b
    i32.add
  )
  ;; Export function
  (export "add" (func $add))
)

Load the wat synchronously:

const { requireWat } = require('require-wat');
const { add } = requireWat('./add.wat');

let result = add(1, 2);

console.log('1 + 2 is ' + result); // 1 + 2 is 3

or asynchronously:

const { requireWatAsync } = require('require-wat');

requireWatAsync('./add.wat')
    .then((wasmExports) => {
        const { add } = wasmExports;
        let result = add(1, 2);

        console.log('1 + 2 is ' + result); // 1 + 2 is 3

    });
