Context7

Context7 Documentation Lookup

Retrieve current documentation and code examples for any programming library directly from the source.

Usage

Use the Python script at scripts/context7.py.

Get Documentation

# Text format (default)
python scripts/context7.py docs \
  --library-id /facebook/react --query "useEffect cleanup function"

# Specific version
python scripts/context7.py docs \
  --library-id /vercel/next.js/v15.1.8 --query "app router middleware"

Search Libraries

Use search only when the library ID is unknown:

python scripts/context7.py search \
  --library react --query "hooks"

Query Tips

• Use detailed, natural language queries for better results
• Good: "How to implement authentication with middleware"
• Bad: "auth"

Common Library IDs

Rules

• Query docs directly when you know the library ID
• Use search only if unsure about the library ID
• Use specific version IDs for consistent results (e.g., /vercel/next.js/v15.1.8)
• Use --format json for structured output
