📊 Extension Management Tips:

🎯 Installation Strategy:

Start with Core 5:

GitLens (version control)
Prettier (code formatting)
ESLint (code quality)
Language-specific pack (Python/React/etc.)
Thunder Client (API testing)

Add Gradually: • Install 2-3 extensions per week • Test each extension thoroughly • Disable unused extensions • Monitor VS Code performance

⚡ Performance Optimization:

Monitor Extension Impact:

Command: "Developer: Show Running Extensions"
Look for: High CPU/Memory usage
Action: Disable problematic extensions

Best Practices: • Only install extensions you actively use • Regularly review and uninstall unused ones • Use extension packs for related functionality • Keep extensions updated

🎯 Workspace-Specific Extensions:

Frontend Project: • ES7+ React snippets • Auto Rename Tag • Live Server • Prettier • ESLint

Backend Project: • Thunder Client • Docker • Language-specific extensions • SonarLint • REST Client

Full-Stack Project: • Combination of above • GitLens for version control • Path Intellisense • TODO Highlight

💡 Hidden Gems:

Settings Sync: • Built into VS Code • Sync extensions across devices • Sign in with GitHub/Microsoft • Never lose your setup again

Extension Recommendations: • VS Code suggests extensions based on your files • Team can share recommended extensions • Create .vscode/extensions.json in projects

Remember: Extensions are tools, not magic. The best extensions are the ones that remove friction from your daily workflow.

Start with the basics, add gradually, and always prioritize productivity over novelty.
