  ;; 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
 
    });
