Getting Started

Setup Process

1. Install the extension in your preferred IDE
2. Sign in with GitHub account
3. Configure preferences for suggestion frequency
4. Start coding - suggestions appear automatically
5. Accept/reject suggestions with keyboard shortcuts

Best Practices for New Users

1. Start with comments - describe what you want to build
2. Use descriptive function names for better suggestions
3. Accept partially and modify suggestions as needed
4. Learn keyboard shortcuts (Tab to accept, Esc to dismiss)
5. Review generated code before committing

Advanced Use Cases

Full-Stack Development

// Type this comment:
// Create a REST API endpoint for user authentication with bcrypt password hashing

// Copilot generates:
app.post('/api/auth/login', async (req, res) => {
  try {
    const { email, password } = req.body;
    const user = await User.findOne({ email });
    
    if (!user || !await bcrypt.compare(password, user.password)) {
      return res.status(401).json({ error: 'Invalid credentials' });
    }
    
    const token = jwt.sign({ userId: user._id }, process.env.JWT_SECRET);
    res.json({ token, user: { id: user._id, email: user.email } });
  } catch (error) {
    res.status(500).json({ error: 'Server error' });
  }
});

Test Generation

# Type function name and Copilot suggests comprehensive tests:
def test_user_registration():
    # Tests valid registration
    # Tests duplicate email handling
    # Tests password validation
    # Tests missing fields

Database Queries

-- Comment: Get user activity summary for the last 30 days
-- Copilot generates complex aggregation queries with proper indexing considerations

Integration with Development Workflow

• Performance optimization suggestions
• Security considerations in generated code

Productivity Impact

Time Savings

• 40-50% faster code completion for repetitive tasks
• Reduced context switching for API documentation lookup
• Faster prototyping with instant boilerplate generation
• Learning acceleration for new languages and frameworks
• Code review preparation with cleaner initial implementations

Quality Improvements

• Consistent patterns across your codebase
• Error handling suggestions for robust applications
• Type safety improvements in TypeScript projects

Common Concerns and Solutions

Code Quality

Issue: Sometimes generates suboptimal code Solution: Always review suggestions, treat as starting point not final solution

Over-reliance

Issue: Developers may lose fundamental coding skills Solution: Use for boilerplate and learning, write critical logic yourself

Privacy

Issue: Code snippets sent to GitHub for processing Solution: Configure to block public code suggestions for sensitive projects

Cost Justification

Issue: Monthly subscription cost Solution: Track time saved - usually pays for itself within first week

Success Stories
