vue-wasm

A Vue plugin to help expose your Web Assembly functions in your Vue application

Install

You can use NPM or Yarn to add this plugin to your project

npm install vue-wasm
# or 
yarn add vue-wasm

Webpack Loader

This package includes a loader to allow you to easily import your .wasm files into your webpack project. Just add the following to your webpack config...

// build/webpack.base.conf.js
module: {
  rules: [
    ...
    {
      test: /\.wasm$/,
      loaders: ['wasm-loader']
    }
  ]
}

Basic

Simply import the vue-wasm plugin and your Web Assembly modules and then install the plugin whilst passing through an object of wasm modules. The key of the each module will be used to namespace the modules

import VueWasm from 'vue-wasm';
import addModule from './assets/wasm/add.wasm';
 
VueWasm(Vue, { modules: { add: addModule } });

Await load

If you need to use your Web Assembly functions in the mounted or created lifecycle hooks, you will need to use a little hack to wait for the plugin to load before initialising your Vue app.

//main.js
import VueWasm from 'vue-wasm';
import add from './assets/wasm/add.wasm';
 
const init = async () => {
  await VueWasm(Vue, { modules: { add } });
  /* eslint-disable no-new */
  new Vue({
    el: '#app',
    template: '<App/>',
    components: { App },
  });
};
 
init();

Usage

This will add a $wasm object to all of your Vue components. Note that your functions are nested under the module key that you used whilst installing the plugin.

// App.vue
mounted() {
  console.log(this.$wasm.add.addOne(2)) // 3
},
