- Write code with ES2015+ syntax (Using Babel)
- E2E tests of Window & Popup & Inject pages (Using Chrome Driver, Selenium Webdriver)
Examples
The example is edited from Redux TodoMVC example.
Popup
The todos state will be saved to chrome.storage.local.
Window
The context menu is created by chrome/extension/background/contextMenus.js.
Inject page
The inject script is being run by chrome/extension/background/inject.js. A simple example will be inject bottom of page(https://github.com/*) if you visit.
If you are receiving the error message Failed to load resource: net::ERR_INSECURE_RESPONSE, you need to allow invalid certificates for resources loaded from localhost. You can do this by visiting the following URL: chrome://flags/#allow-insecure-localhost and enabling Allow invalid certificates for resources loaded from localhost.
