jscodeshift Codemods

Core Philosophy: Transform AST nodes, not text. Let recast handle printing to preserve formatting and structure.

When to Use

Use codemods for:

• API migrations - Library upgrades (React Router v5→v6, enzyme→RTL)
• Pattern standardization - Enforce coding conventions across codebase
• Deprecation removal - Remove deprecated APIs systematically
• Large-scale refactoring - Rename functions, restructure imports, update patterns
