Workerpool embedded worker example

In a browser environment, the script argument in workerpool.pool(script) can also be a data URL like 'data:application/javascript;base64,...'. This allows embedding the bundled code of a worker in your main application, which is demonstrated in this example.

!!! Note that this example only works in the browser, not in node.js !!!

Run

Install the dependencies:

npm install

Build the embedded worker (dist/worker.embedded.js) and the bundled version of app.js (dist/app.bundle.js):

npm run build

Then open app.html in your browser.

How does it work?

1. The script worker.js is bundled into dist/worker.bundle.js using Webpack
2. From the worker bundle, a base64 encoded data url is created and stored in a JavaScript file dist/worker.embedded.js. This file looks like:

   module.exports = 'data:application/javascript;base64,...';
   

3. The file app.js loads the embedded worker and passes it to the worker pool like:

```js
var workerDataUrl = require('./dist/worker.embedded');

// create a worker pool
var pool = workerpool.pool(workerDataUrl);
```

4. The application app.js is bundled using Webpack, and the bundle is loaded into app.html.
