源代码目录结构

Electron 的源代码分为几个部分，主要遵循 Chromium 的分离约定。

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
├── build/ - Build configuration files needed to build with GN.
├── buildflags/ - Determines the set of features that can be conditionally built.
├── chromium_src/ - Source code copied from Chromium that isn't part of the content layer.

|                  providing a consumer app.
├── docs/ - Electron's documentation.
|   ├── api/ - Documentation for Electron's externally-facing modules and APIs.
|   ├── development/ - Documentation to aid in developing for and with Electron.

|   |   ├── api/ - API implementation for main process modules.
|   |   └── remote/ - Code related to the remote module as it is
|   |                 used in the main process.
|   ├── common/ - Relating to logic needed by both main and renderer processes.
|   |   └── api/ - API implementation for modules that can be used in
|   |              both the main and renderer processes
|   ├── isolated_renderer/ - Handles creation of isolated renderer processes when

|   ├── renderer/ - Renderer process initialization code.
|   |   ├── api/ - API implementation for renderer process modules.
|   |   ├── extension/ - Code related to use of Chrome Extensions
|   |   |                in Electron's renderer process.
|   |   ├── remote/ - Logic that handles use of the remote module in
|   |   |             the main process.
|   |   └── web-view/ - Logic that handles the use of webviews in the
|   |                   renderer process.
|   ├── sandboxed_renderer/ - Logic that handles creation of sandboxed renderer

|                 environments in Web Workers.
├── patches/ - Patches applied on top of Electron's core dependencies

├── shell/ - 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.

|   |   ├── 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.
