This documentation is not yet complete, but the code is functional.
Clone the repo and install the required dependencies:
git clone --depth 1 --branch main https://github.com/ErrorGamer2000/extension-boilerplate.git your-project-name
cd your-project-name
npm install
To start the development script, simply run
npm start
The extension's manifest is pre-populated with a basic configuration, although it is most likely nothing like what you will need in the project. The only thing that needs to remain the same is the tabs
permission, which is used for the livereloading of the background service worker.
To add a web page to the extension, simply make a new directory in src/pages
, and add an index file (js, ts, jsx, or tsx) and an index.html
file with the following:
<html>
<head>
<%= htmlWebpackPlugin.tags.headTags %>
</head>
<body>
<%= htmlWebpackPlugin.tags.bodyTags %>
<!-- Your elements here -->
</body>
</html>
This boilerplate supports live reload by default. All you have to do is import the correct file from the livereload
folder. The background and popup scripts already have these imports, as well as the settings page. To add livereload to your page, simply add
import "../../livereload/page";
To the top of the script.
In order to reload the extension's service worker (because of MV3), the extension comes with, and will automatically open, a reload
page, which connects to the livereload server and will send a message to the service worker, waking it up and reloading the extension. Closing this tab will disable livereload during development.
None of the livereload code will be added to the production code, thanks to the if-def
webpack plugin, although the reload
page will still be emitted.
The livereload server uses localhost port 5001
by default, but this can be canged in the config/port.json
file;
By default, the boilerplate ships with the configuration for a single content script.
