Team Members See Prompt

When team members open the workspace, they’ll see a prompt to install recommended extensions

​
Personal Recommendations

VS Code suggests extensions based on:
  • Files you open (e.g., Python files suggest Python extensions)
  • Workspace contents (e.g., package.json suggests Node.js extensions)
  • Popular extensions in your language/framework
Accept recommendations for languages you work with frequently. VS Code’s suggestions are based on file types and installed tools.

​
Extension Details

Click an extension to view detailed information:
  • Overview - Description, features, and getting started
  • Feature Contributions - Commands, settings, and other contributions
  • Changelog - Version history and updates
  • Dependencies - Required extensions
  • Extension Pack - If the extension bundles multiple extensions
  • Rating & Reviews - User feedback and ratings
  • Resources - Links to repository, issues, license

​
Configuring Extensions

Many extensions add settings you can customize:
1

Open Settings

Go to File → Preferences → Settings (or Ctrl+, / Cmd+,)
2

Search Extension Name

Type the extension name to filter its settings
3

Modify Settings

Adjust settings in the UI or edit settings.json directly
{
  "emmet.showExpandedAbbreviation": "always",
  "emmet.triggerExpansionOnTab": true,
  "emmet.includeLanguages": {
    "javascript": "javascriptreact"
  }
}

​
Extension Packs

Extension packs bundle multiple related extensions together. Installing an extension pack installs all included extensions. Examples from VS Code’s ecosystem:
  • Language packs (Python, Java, C++)
  • Framework packs (Vue, React, Angular)
  • Tool packs (Docker, Kubernetes, Azure)
Be careful when installing large extension packs. They may include extensions you don’t need, which can slow down VS Code.

​
Finding Quality Extensions

Look for these indicators of high-quality extensions: ✓ Verified Publisher - Publisher identity verified by Microsoft
✓ High Rating - 4+ stars with many reviews
✓ Active Maintenance - Recent updates and changelog
✓ Good Documentation - Clear README and examples
✓ Many Installs - Popular with the community
✓ Open Source - Source code available for inspection

​
