Worker Loader

Worker loader for Webpack.

Install

npm i -D worker-loader

Usage

Documentation: Using loaders

Import the worker file:

// main.js
var MyWorker = require("worker-loader!./file.js");

var worker = new MyWorker();
worker.postMessage({a: 1});
worker.onmessage = function(event) {...};
worker.addEventListener("message", function(event) {...});

You can also inline the worker as a blob with the inline parameter:

var MyWorker = require("worker-loader?inline!./myWorker.js");

Inline mode will also create chunks for browsers without supporting of inline workers, to disable this behavior just set fallback parameter as false:

var MyWorker = require("worker-loader?inline&fallback=false!./myWorker.js");

To set a custom name for the output script, use the name parameter. The name may contain the string [hash], which will be replaced with a content-dependent hash for caching purposes. For example:

var MyWorker = require("worker-loader?name=outputWorkerName.[hash].js!./myWorker.js");

The worker file can import dependencies just like any other file:

// file.js
var _ = require('lodash')

var o = {foo: 'foo'}

_.has(o, 'foo') // true

You can even use ES6 modules if you have the babel-loader configured:

// file.js
import _ from 'lodash'

let o = {foo: 'foo'}

_.has(o, 'foo') // true
