## What it is
A component library of web components for building webview-based extensions in Visual Studio Code, matching the editor's design language. It supports any tech stack (React, Vue, Svelte) and automatically adapts to the current editor color theme with built-in accessibility.

## Use cases
- build a vscode extension ui inside a webview
- make extension panels match the vscode editor theme
- add accessible buttons and inputs to a vscode webview
- use vscode-styled components in a react webview extension
- style webview ui consistently with the rest of the editor

## When to choose
- building a webview-based vscode extension that must match the editor's design language
- you need framework-agnostic web components with automatic theme support

## When to avoid
- starting a new project, since the toolkit is deprecated as of January 1, 2025
- building non-webview vscode extension UIs (tree views, status bars)
- you need long-term maintained support
