Companies House ++

Chrome plugin to inject the company ownership hierarchy into a Companies House page.

Under the hood, it uses the Companies House API to recursively fetch people of significant control (PSCs), and then search for corporate PSCs in the search API.

This project is on the react-typescript-chrome-extension-boilerplate, with inspiration on using React in content-scripts and hot-reloading.

Getting started

Navigate to the project directory and install the dependencies.

$ yarn

To build the extension, and rebuild it when the files are changed, run

1. Open Chrome.
2. Navigate to chrome://extensions.
3. Enable Developer mode.
4. Click Load unpacked.
5. Select the dist directory.
