VS Code Extension

Build VS Code extensions from scratch or convert existing web apps into portable, shareable extensions.

Architecture

VS Code extensions run in two contexts:

1. Extension Host (Node.js) — Backend logic, file access, VS Code APIs
2. Webviews (browser sandbox) — Custom UIs with HTML/CSS/JS (React, Vue, vanilla)

Build stack: TypeScript + esbuild (extension) + Vite (webviews)
