# ts-migrate

*ts-migrate* is a tool for helping migrate code to TypeScript.
It takes a JavaScript, or a partial TypeScript, project in and gives a compiling TypeScript project out.

*ts-migrate* is intended to accelerate the TypeScript migration process. The resulting code will pass the build, but a followup is required to improve type safety. There will be lots of `// @ts-expect-error`, and `any` that will need to be fixed over time. In general, it is a lot nicer than starting from scratch.

*ts-migrate* is designed as a set of plugins so that it can be pretty customizable for different use-cases. Potentially, more plugins can be added for addressing things like improvements of type quality or libraries-related things (like prop-types in React).

Plugins are combined into migration configs. We currently have two main migration configs:

* for the main JavaScript → TypeScript migration
* for the reignore script

These configs can be moved out of the default script, and people can add custom configs with a different set of plugins for their needs.

You can find instructions on how to install and run ts-migrate in the [main package](./packages/ts-migrate/). If you find any [issues](https://github.com/airbnb/ts-migrate/issues) or have ideas for improvements, we welcome your [contributions](https://github.com/airbnb/ts-migrate/blob/master/CONTRIBUTING.md)!
