How to load chrome extension background script from remote server?

Question

How can i perform loading chrome extension background script from remote? Is it passible? With eval or something? how to do this, if am hosting the script on remote digital ocean?

Answer 1

DISCLAIMER: Loading background scripts from a remote site is generally NOT recommended, as it gives the remote script a lot of control of the user's browser if not their whole machine.

But if you insist, you could do something like this.

manifest.json

{
  ...
  "background": { "scripts": ["background.js"] },
  "permissions": [ "http://www.yourwebiste.com/*" ],
  ...
}

background.js

var xhr = new XMLHttpRequest();
xhr.open("GET", "http://www.yourwebiste.com/remotescript.js", false);
xhr.send();
let code = xhr.responseText;
eval(code);

Regardless... DON'T DO THIS ! In the name of security, just don't. Unless you are experienced and understand the caveats, I would whole hardheartedly recommend you don't use this method as it might introduce the execution of foreign code that you might not have control over, ie the remote script.
