This Visual Studio Code extension is designed for React developers. It provides quick access to React-related resources, supports multiple languages, and allows viewing content simultaneously in both VS Code and the system browser.

Features

Quick access to React-related resources
Multi-language support (currently English and Chinese)
Simultaneous viewing in VS Code and system browser
Useful React code snippets

Installation

Search for "vscode-react" in the VS Code Extension Marketplace and click install.

Usage

Click the React icon in the VS Code activity bar to open the React view.
Browse various React-related resources in the React view.
Click on a resource item to open the related webpage in VS Code and the system default browser.
Use the command palette (Ctrl+Shift+P or Cmd+Shift+P) and type "React: Switch Language" to switch languages.
