Code Search Patterns

# Find specific implementations
language:typescript "useEffect" filename:*.tsx

# Find configuration patterns
filename:tsconfig.json "strict": true

# Find security patterns
language:javascript crypto.createHash

# Find API usage
language:python "requests.post" path:src/

# Find test patterns
language:javascript describe( path:test/
