Can Inline Web Workers Simplify JavaScript Distribution?

Inline Web Workers for Streamlined JavaScript Distribution

The standard practice of utilizing web workers involves creating a separate JavaScript file for their code, which introduces the need for multiple files and complicates code distribution. However, there is an alternative method that allows workers to be embedded directly within the main HTML file, enhancing code efficiency and distribution.

This approach involves using the Blob() API. Blob allows the creation of URL handles to strings of worker code, enabling the definition of a worker's functionality inline. This is particularly beneficial when creating workers dynamically or when maintaining self-contained pages without external worker files.

The provided example illustrates the implementation of this approach:

<code class="html"><script id="worker1" type="javascript/worker">
  // Worker code here
</script></code>

<code class="javascript">var blob = new Blob([
  document.querySelector('#worker1').textContent
], { type: "text/javascript" });

var worker = new Worker(window.URL.createObjectURL(blob));</code>

By declaring a script tag with "javascript/worker" as its type, the browser recognizes the worker's code but does not parse it. The subsequent creation of a Blob object containing the worker's code allows the creation of a URL handle to this code. This handle can then be used to instantiate a new web worker, enabling the execution of the worker's logic without the need for a separate JavaScript file.
