ts-migrate is a CLI tool from Airbnb that converts JavaScript or partial TypeScript projects into compiling TypeScript projects using a plugin-based codemod pipeline. It accelerates large-scale migrations by producing code that builds immediately, though it relies on @ts-expect-error and any annotations that require later cleanup.
Use cases
- migrate a large JavaScript codebase to TypeScript
- convert frontend app from JS to TS quickly
- codemod a partial TypeScript project to fully compile
- reignore existing TypeScript errors after upgrading
- write custom migration plugins for codebase-specific transforms
When to choose
- you need to migrate a large JavaScript codebase to TypeScript incrementally and get a compiling build fast
- you want a plugin-based, customizable codemod framework for TS migrations
- you need to suppress and triage type errors at scale with a reignore pass
When to avoid
- you want fully type-safe output with no manual cleanup
- you are starting a new project and can write TypeScript from scratch
- your codebase is small enough to migrate by hand
