Source Code Directory Structure
Electron的源代码被分成几个部分，大部分遵循Chromium的分离惯例。
您可能需要熟悉Chromium的多进程架构以更好地理解源代码。
源代码结构
Electron
├── atom/ - C++ source code.
| ├── app/ - System entry code.
| ├── browser/ - The frontend including the main window, UI, and all of the
| | main process things. This talks to the renderer to manage web pages.
| | ├── ui/ - Implementation of UI stuff for different platforms.
| | | ├── cocoa/ - Cocoa specific source code.
| | | ├── win/ - Windows GUI specific source code.
| | | └── x/ - X11 specific source code.
| | ├── api/ - The implementation of the main process APIs.
| | ├── net/ - Network related code.
| | ├── mac/ - Mac specific Objective-C source code.
| | └── resources/ - Icons, platform-dependent files, etc.
| ├── renderer/ - Code that runs in renderer process.
| | └── api/ - The implementation of renderer process APIs.
| └── common/ - Code that used by both the main and renderer processes,
| including some utility functions and code to integrate node's message
| loop into Chromium's message loop.
| └── api/ - The implementation of common APIs, and foundations of
| Electron's built-in modules.
├── chromium_src/ - Source code that copied from Chromium.
├── default_app/ - The default page to show when Electron is started without
| providing an app.
├── docs/ - Documentations.
├── lib/ - JavaScript source code.
| ├── browser/ - Javascript main process initialization code.
| | └── api/ - Javascript API implementation.
| ├── common/ - JavaScript used by both the main and renderer processes
| | └── api/ - Javascript API implementation.
| └── renderer/ - Javascript renderer process initialization code.
| └── api/ - Javascript API implementation.
├── spec/ - Automatic tests.
├── electron.gyp - Building rules of Electron.
└── common.gypi - Compiler specific settings and building rules for other
components like `node` and `breakpad`.
其他目录的结构
脚本- 用于建筑，包装，测试等开发目的的脚本
工具- gyp文件使用的帮助程序脚本，与script放置在此处的脚本不应该直接由用户调用。
供应商- 第三方依赖关系的源代码，我们没有使用third_party它作为名称，因为它会将它与Chromium的源代码树中的相同目录混淆。
node_modules- 用于构建的第三方节点模块。
out- 临时输出目录ninja。
dist-script/create-dist.py创建分发时由脚本创建的临时目录。
external_binaries- 下载不支持构建的第三方框架的二进制文件gyp。
保持Git子模块最新
Electron存储库有一些自销的依赖关系，可在/ vendor目录中找到。偶尔你会在运行时看到类似这样的消息git status：
$ git status
modified: vendor/libchromiumcontent (new commits)
modified: vendor/node (new commits)
要更新这些依赖项，运行以下命令：
git submodule update --init --recursive
如果你发现自己经常运行这个命令，你可以在你的~/.gitconfig文件中为它创建一个别名：
[alias]
su = submodule update --init --recursive
