How to read and write to/from DOM

[mrfzd]

First of all, thank you for this great boilerplate project! It's simply awesome and well put together! So thank you so much for the all efforts, time and the LOVE you have put into this so far!

So after fiddling around, I've been trying to figure out a way to read DOM elements (for any given website that I open up the the Chrome ext. popup)?
Also, how could I highlight and inject elements into any given website i.e. google.com (via the popup)?

Thank you

Any idea?

You need to communicate popup with content script - use communication https://developer.chrome.com/docs/extensions/develop/concepts/messaging
To run a script use executeScript or just normal content_script crxjs/chrome-extension-tools#859
