Electron enables you to create desktop applications with pure JavaScript by providing a runtime with rich native (operating system) APIs. You could see it as a variant of the Node.js runtime that is focused on desktop applications instead of web servers.
The old "Quick Start" document that used to live here has been split up into two documents:
- To check out how a simple Electron app is built, see Writing Your First Electron App
- To check out the process architecture, see Main and Renderer Processes.
