How can I store data on the backend script and use it in the content script of my chrome extension?

Question

I want to know how my content script can communicate with the backend script. I mean sending request from content script and get responce from backend script based on request.

@HaibaraAi Simple as that. I really wonder if people use search engines these days. — Transcendental, Jun 23 '16 at 12:27

You should refer to message passing: https://developer.chrome.com/extensions/messaging

When sending a message from content script to background script you'll simply use:

chrome.runtime.sendMessage({greeting: "hello"}, function(response) {
  console.log(response.farewell);
});

When it's the other way around you'll need to specify the tab as well (please refer to the link above).
