CRX Reload is a free Chrome add-on developed by Huge Letters. It falls under the category of Browsers and is categorized as an Add-ons & Tools subcategory. This handy tool is designed to automatically reload your Chrome extension during development with an HTTP request.

During the development of a Chrome extension, it is often necessary to reload or toggle the unpacked extension on and off whenever updates are made to the code. With CRX Reload, this process can be automated, allowing you to trigger reloads at any time you desire. To use this extension, simply follow these steps:

1. Install the "socket.io" npm package.

2. Create a new server using the code: `const io = new Server(PORT)`.

3. Emit reload events when needed, such as on build end or file change, using `io.emit("crx-reload")`.

In the extension's popup, you can configure the port you would like to use and toggle the extension off when it is not needed. It is recommended to enable the extension only during development, as it utilizes websockets. The popup label will be colored red or green depending on whether it was able to establish a connection with your server.

Please note that CRX Reload does not reflect changes made to your 'manifest.json' through these reloads, as the Chrome API only allows toggling extensions on and off and not actually reloading them. To perform a full reload, manual intervention is required.
