Chrome 扩展支持

Electron 支持 Chrome 扩展API的子集，主要是支持 DevTools 扩展和 Chromium-internal 扩展，但它同时也支持一些其他扩展能。

Note: Electron does not support arbitrary Chrome extensions from the store, and it is a non-goal of the Electron project to be perfectly compatible with Chrome’s implementation of Extensions.

加载扩展

Electron 只支持加载未打包的扩展 (即不能使用 .crx 文件)。插件会被安装到每一个会话。要加载扩展，请调用 ses.loadextension：

const { session } = require('electron')
session.loadExtension('path/to/unpacked/extension').then(({ id }) => {
  // ...
})

Loaded extensions will not be automatically remembered across exits; if you do not call loadExtension when the app runs, the extension will not be loaded.

注意，仅能在持久 session 中加载扩展。尝试将扩展加载到内存 session 中会出现错误。

有关加载、卸载和查询活动扩展的更多信息，请查阅 session 文档。

The following properties of chrome.runtime are supported:

chrome.runtime.lastError
chrome.runtime.id

The following methods of chrome.runtime are supported:
