GOV.UK Toolkit for Chrome and Firefox

Allows easy switching between the different GOV.UK environments and content representations. Inspired by the govuk-bookmarklets.

1. Download the source from GitHub and unzip.
2. Visit chrome://extensions in your browser.
3. Ensure that the Developer mode checkbox in the top right-hand corner is checked.
4. Click Load unpacked extension… to pop up a file selection dialog.
5. Navigate to src in the extension directory, and select it.
6. Visit any page on GOV.UK.

1. Download the source from GitHub and unzip.
2. Visit about:debugging in your browser.

Running the tests

You'll need jasmine-browser, which you can set up with:

$ npm install

You can then run the tests with:

$ npm test

This will start a server and run the tests in a browser (chrome by default).

If you want the browser to remain open with the test results, you can use

$ npx jasmine-browser-runner serve

..then navigate to http://localhost:8888/

Releasing the extension

When a new version is merged to main, a new version of the extension is automatically packaged up and published to Firefox Add-ons and to Chrome web store. See releasing.md
