Estrutura de Diretório do Código Fonte

The source code of Electron is separated into a few parts, mostly following Chromium on the separation conventions.

You may need to become familiar with Chromium's multi-process architecture to understand the source code better.

Structure of Source Code

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.
├── default_app/ - A default app run when Electron is started without
| providing a consumer app.
├── docs/ - Electron's documentation.
| ├── api/ - Documentation for Electron's externally-facing modules and APIs.

| └── tutorial/ - Tutorial documents for various aspects of Electron.
├── lib/ - JavaScript/TypeScript source code.
| ├── browser/ - Main process initialization code.
| | ├── 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
| | contextIsolation is enabled.
| ├── renderer/ - Renderer process initialization code.
| | ├── api/ - API implementation for renderer process modules.

| ├── 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.
├── spec/ - Components of Electron's test suite run in the renderer process.
├── spec-main/ - Components of Electron's test suite run in the main process.
└── BUILD.gn - Building rules of Electron.
