应用调试

¥Application Debugging

每当你的 Electron 应用未按你希望的方式运行时，一系列调试工具可能会帮助你发现编码错误、性能瓶颈或优化机会。

¥Whenever your Electron application is not behaving the way you wanted it to, an array of debugging tools might help you find coding errors, performance bottlenecks, or optimization opportunities.

渲染进程​

¥Renderer Process

调试单个渲染器进程的最全面的工具是 Chromium 开发者工具集。它可用于所有渲染器进程，包括 BrowserWindow、BrowserView 和 WebView 的实例。你可以通过在实例的 webContents 上调用 openDevTools() API 以编程方式打开它们：

¥The most comprehensive tool to debug individual renderer processes is the Chromium Developer Toolset. It is available for all renderer processes, including instances of BrowserWindow, BrowserView, and WebView. You can open them programmatically by calling the openDevTools() API on the webContents of the instance:

const { BrowserWindow } = require('electron')

const win = new BrowserWindow()
win.webContents.openDevTools()

Google 提供 其开发者工具的优秀文档。我们建议你熟悉它们 - 它们通常是任何 Electron 开发者工具带中最强大的实用程序之一。

¥Google offers excellent documentation for their developer tools. We recommend that you make yourself familiar with them - they are usually one of the most powerful utilities in any Electron Developer's tool belt.

主进程​

¥Main Process

调试主进程有点棘手，因为你无法为其打开开发者工具。由于 Google / Chrome 和 Node.js 之间的更密切合作，Chromium 开发者工具可以实现 用于调试 Electron 的主进程，但你可能会遇到诸如 require 之类的奇怪情况没有出现在控制台中。

¥Debugging the main process is a bit trickier, since you cannot open developer tools for them. The Chromium Developer Tools can be used to debug Electron's main process thanks to a closer collaboration between Google / Chrome and Node.js, but you might encounter oddities like require not being present in the console.

有关详细信息，请参阅 调试主进程文档。

¥For more information, see the Debugging the Main Process documentation.

V8 崩溃​

¥V8 Crashes

如果 V8 上下文崩溃，DevTools 将显示此消息。

¥If the V8 context crashes, the DevTools will display this message.

DevTools was disconnected from the page. Once page is reloaded, DevTools will automatically reconnect.

可以通过 ELECTRON_ENABLE_LOGGING 环境变量启用 Chromium 日志。有关详细信息，请参阅 环境变量文档。

¥Chromium logs can be enabled via the ELECTRON_ENABLE_LOGGING environment variable. For more information, see the environment variables documentation.

或者，可以传递命令行参数 --enable-logging。更多信息请参见 命令行开关文档。

¥Alternatively, the command line argument --enable-logging can be passed. More information is available in the command line switches documentation.
