How to send data to my Google Chrome extension from a local web server?

Question

JavaScript

I have a python application that, according to certain rules, must poke buttons on the site through Chrome. I don’t want to use Selenium, I was thinking of writing an extension for chrome that will accept commands from a python script and poke buttons on the site. Is such an implementation possible, and if so, in which direction to dig, what to google?

Answer 1

Answer 2

Use WebSocket to keep in touch with your server and background process in the extension at all times.
