How to import ES6 modules in content script for Chrome Extension
问题 In Chrome 61 , support for modules in JavaScript was added. Right now I am running Chrome 63. I am trying to use import / export syntax in Chrome extension content script to use modules. In manifest.json : "content_scripts": [ { "js": [ "content.js" ], } ] In my-script.js (same directory as content.js ): 'use strict'; const injectFunction = () => window.alert('hello world'); export default injectFunction; In content.js : 'use strict'; import injectFunction from './my-script.js';
