  "editor.suggest.shareSuggestSelections": true,
  "files.autoSave": "onFocusChange",
  
  // IntelliSense configuration
  "typescript.suggest.autoImports": true,
  "typescript.updateImportsOnFileMove.enabled": "always"
}

Essential Keyboard Shortcuts

// keybindings.json
[
  {
    "key": "ctrl+shift+i",
    "command": "github.copilot.generate",
    "when": "editorTextFocus"
  },
  {
    "key": "ctrl+shift+/",
    "command": "github.copilot.openChat",
    "when": "editorTextFocus"
  },
  {
    "key": "alt+]",
    "command": "editor.action.inlineSuggest.showNext",
    "when": "inlineSuggestionVisible"
  },
  {
    "key": "alt+[",
    "command": "editor.action.inlineSuggest.showPrevious",
    "when": "inlineSuggestionVisible"
  }
]

AI Workflows in VSCode

1. Comment-Driven Development

// Create a function to validate email with regular expressions
function validateEmail(email) {
  // GitHub Copilot will automatically generate:
  const emailRegex = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  return emailRegex.test(email);
}

// Create a class to handle users with complete CRUD
class UserManager {
  // Copilot will complete constructor, CRUD methods, validations...
}

2. Intelligent Refactoring

  1. Select the code to refactor
  2. Open GitHub Copilot Chat (Ctrl+Shift+/)
  3. Write: “Refactor this code to make it more readable and efficient”
  4. Apply suggestions with one click

3. Automatic Test Generation

// Original function
function calculateDiscount(price: number, percentage: number): number {
  return price * (1 - percentage / 100);
}

// In Copilot Chat: "Generate unit tests for this function"
// Automatic result:
describe('calculateDiscount', () => {
  it('should calculate 10% discount correctly', () => {
    expect(calculateDiscount(100, 10)).toBe(90);
  });
  
  it('should handle zero discount', () => {
    expect(calculateDiscount(100, 0)).toBe(100);
  });
  
  it('should handle 100% discount', () => {
    expect(calculateDiscount(100, 100)).toBe(0);
  });
});

Best Practices for AI in VSCode

1. Effective Prompt Writing

❌ Vague prompt:

// do something with users

✅ Specific prompt:

// Create an asynchronous function that fetches users from a REST API,
// handles HTTP errors and returns an array of typed User objects

2. Project-Specific Configuration

Create a project-specific .vscode/settings.json:

{
  "github.copilot.enable": {
    "javascript": true,
    "typescript": true,
    "python": false  // Disable in specific projects
  },
  "files.associations": {
    "*.config.js": "javascript"
  }
}

3. Extension Management

Create VSCode profiles for different types of development:

  • Web Profile: Copilot + Live Server + ES7+ Snippets
  • Python Profile: Copilot + Python + Pylance + Jupyter
  • Mobile Profile: Copilot + Flutter + React Native Tools

Common Problem Solutions

GitHub Copilot Doesn’t Suggest

  1. Verify authentication: Ctrl+Shift+P → “GitHub: Sign In”
  2. Check configuration: Make sure it’s enabled for your language
  3. Restart VSCode: Sometimes a restart is necessary
  4. Update extension: Keep Copilot always updated

Slow Performance

  1. Disable unnecessary extensions: Only use the AI you need
  2. Adjust configurations: 
    {
  "editor.suggest.maxVisibleSuggestions": 5,
  "github.copilot.inlineSuggest.count": 3
}
  3. Increase memory: "typescript.tsc.autoDetect": "off"

Integration with GitHub Codespaces

VSCode + AI works perfectly in the cloud with GitHub Codespaces:

  1. Open any repository on GitHub
  2. Press . to open VSCode Web
  3. Install AI extensions from the marketplace
  4. Program with AI from any device
