React Chrome Extension Boilerplate
Boilerplate for Chrome Extension React.js project.
Features
- Simple React/Redux examples of Chrome Extension Window & Popup & Inject pages
- Hot reloading React/Redux (Using Webpack and React Transform)
- 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.
