Best Practices

Setup and Configuration

1. Initial Scan: Allow Context7 to perform an initial full scan of your codebase
2. Ignore Files: Configure .gitignore-style patterns for files to exclude from analysis
3. Update Frequency: Set appropriate update intervals for your project size
4. Memory Management: Configure memory limits for large codebases

Effective Usage

• Start Broad: Begin with high-level architectural queries
• Drill Down: Use progressive refinement to explore specific areas
• Cross-Reference: Use relationship mapping to understand connections
• Regular Updates: Keep analysis current with frequent updates

Team Adoption

• Training: Provide team training on effective Context7 usage
• Standards: Establish conventions for using Context7 in code reviews
• Documentation: Use Context7 to maintain up-to-date project documentation
• Onboarding: Include Context7 exploration in new developer onboarding

Performance Considerations

Resource Usage

• Memory: Analysis requires significant memory for large codebases
• CPU: Initial analysis is CPU-intensive but subsequent updates are efficient
• Storage: Maintains analysis cache for faster subsequent operations
• Network: Minimal network usage after initial setup

Optimization Tips

• Incremental Analysis: Use incremental updates for better performance
• Selective Scanning: Focus analysis on specific directories or file types
• Cache Management: Regularly clean analysis cache for optimal performance
• Resource Limits: Set appropriate limits based on your system capabilities

Advanced Features
