Maintaining large-scale JavaScript codebases is never easy, but it's especially challenging when migrating breaking changes. IDEs with refactoring capabilities may help in simple scenarios. However, when your codebase is a widely dependent library, every time you make a breaking change you have to go through a series of client codebases to make the appropriate updates — which requires human oversight and needs to be done manually. jscodeshift, a toolkit to refactor JavaScript and TypeScript, helps relieve this pain. It can parse your code to abstract syntax trees (AST) and provides an API to manipulate the tree with various transformations (e.g., adding, renaming and deleting properties from existing components) and then exports the tree as final source code. jscodeshift also comes with a simple unit testing utility, which can apply test-driven development for writing migration codemods. We've found jscodeshift to be quite helpful when maintaining design systems.
