I wanted to test out the new WebAssembly support so I started up a simulation and added the WebAssembly example from the screeps documentation to my main.js file and the accompanying addTwo.wasm binary to my branch:

// This will return an ArrayBuffer with `addTwo.wasm` binary contents

const bytecode = require('addTwo');

const wasmModule = new WebAssembly.Module(bytecode);

const imports = {};

// Some predefined environment for Emscripten. See here:

// https://github.com/WebAssembly/tool-conventions/blob/master/DynamicLinking.md

imports.env = {

    memoryBase: 0,

    tableBase: 0,

    memory: new WebAssembly.Memory({ initial: 256 }),

    table: new WebAssembly.Table({ initial: 0, element: 'anyfunc' })    

};

const wasmInstance = new WebAssembly.Instance(wasmModule, imports);

console.log(wasmInstance.exports._addTwo(2,3));

The issue I ran into however was that the initial line for requiring the addTwo.wasm file would produce the following debug error:

TypeError: i.bufferFromBase64 is not a function

Now I booted up a few other WebAssembly examples (cppreeps and a custom WebAssembly file of my own that jsut included a dumby function). Every time I would use require() to bring in the .wasm file I would receive a bufferFromBase64 is not a function TypeError.

Has anyone else either ran into a similar issue when trying to setup WebAssembly? Thanks.
