在 Chrome 扩展脚本之间共享功能的最佳方式是什么？

Question

I have a function defined in background.js that I use inside of background.js. I also want to use that function in options.html's options.js without rewriting it there. I know I can do chrome.extension.getViews() to get the global objects of other extension scripts. I can also send a message from options.js and have background.js run the function with data from options.js. Is there an another method? More importantly, is one preferred over the other?

Answer 1

To use the function in the background.js and options.js files you need to create a 3rd file to abstract the function into (I will use helper.js for the example). After the function is abstracted you can use the export statement which will allow it to be importable by the background and options scripts.

Helper.js:

export function reusableFunction () {
  // your code here
}

background script:

import { reusableFunction } from './helper.js';
