To use the development version:

1. Clone the repo: git clone https://github.com/RetireJS/retire.js
2. Install the requirements: npm - https://docs.npmjs.com/downloading-and-installing-node-js-and-npm
3. Run ./build_chrome.sh (Linux) or ./build_chrome.bat (Windows) from the root of the repo
4. Open chrome://extensions/
5. Check "Developer mode"
6. Click "Load unpacked" at the top left, and select the chrome/extension or chrome/extension-no-func folder inside the repo
7. Use and develop

To test the reporting, you can visit the demo page at https://erlend.oftedal.no/blog/retire/

The default extension loads the downloaded scripts in an iframe and then tries to invoke JavaScript functions from the downloaded repo (like jQuery.fn.version) in a sandbox to try to detect certain libraries. If this is not acceptable security-wise, you can use extension-no-func, which does not invoke those functions.

Be wary when updating the files, as files not related to no-func, are symlinked between the two versions to avoid having to update in both places.
