TypeTags .WebAssemblyInstance

Overview#

A WebAssembly.Instance object is a stateful, executable instance of a WebAssembly.Module. Instance objects contain all the Exported WebAssembly functions that allow calling into WebAssembly code from JavaScript.

Usage#

import { TypeTags } from 'typetags'

const importObject = {
  imports: {
    imported: function (arg) {
      console.log(arg)
    },
  },
}

fetch('simple.wasm')
  .then((response) => response.arrayBuffer())
  .then((bytes) => {
    let mod = new WebAssembly.Module(bytes)
    let instance = new WebAssembly.Instance(mod, importObject)
    instance.exports.exported()
    return [mod, instance]
  })

TypeTags.get(instance) === TypeTags.WebAssemblyInstance
// → true

console.log(TypeTags.WebAssemblyInstance)
// → [object WebAssembly.Instance]
