codemod 命令

常用示例

说明

codemod assists with large-scale codebase refactoring that requires human oversight and judgment. Unlike fully automated find-and-replace tools, codemod presents each potential change interactively, showing a colored diff and prompting whether to accept, reject, or manually edit the modification. This interactive approach is ideal for complex refactoring tasks like renaming functions across hundreds of files, updating API calls, or modernizing code patterns where context matters. The tool uses Python regex for pattern matching and displays sufficient surrounding code to make informed decisions. Developed by Facebook and released as open source, codemod was designed for their massive PHP and JavaScript codebases. While the original project is now archived, it pioneered the interactive refactoring workflow later adopted by tools like fastmod and jscodeshift.
