Codemods how to support your users with breaking changes delivery
summary
A concrete claim: codemods let libraries ship breaking changes while keeping feedback flowing by automating repetitive refactors. The demo uses jscodeshift and AST transforms to replace a Breadcrumbs Label with a Link, adds an href="#" placeholder, and runs tests with defineInlineTest. The codemod runs via a CLI that writes changes to files and commits them to Git, it works for simple patterns but admits edge cases where the transform fails.
