Requirise-wasm
A utility module to convert wasm to a requirable buffer object that you can pass to WebAssembly.instantiate or WebAssembly.Module.
Installation
npm i requirise-wasm

Command line usage
requirise-wasm -i ./module.wasm -o ./module.wasm.js

-o/--output PATH
The path to the output requirable file. Not needed if piping out from this tool.
-v/--version

Programmatic usage
This module exports a function that can take a buffer and return a string that you can write to a file.
const requirise = require('requirise-wasm')
const fs = require('fs')
const someWASM = fs.readFileSync('/path/to/some.wasm')
const requirableString = requirise(someWasm)
fs.writeFileSync('/path/to/some.wasm.js')
Using the WASM you just wrote to a file
To use the WASM you just wrote to a file, simply require it and pass it to WebAssembly.Module
or WebAssembly.instantiate
const wasmBuffer = require('/path/to/some.wasm.js')
// export a WASM module that is initialised synchronously
module.exports = new WebAssembly.Instance(WebAssembly.Module(wasmBuffer))
