Convert Flow code to TypeScript.
The goal of this project is to provide a tool that can translate 95% of Flow
to TypeScript while maintaining a high percentage of the existing type
information. We don't want to convert code and end up with everything using
any. We also want to avoid having to make a lot of manual changes to files
afterwards, e.g. changing
yarn global add @khanacademy/flow-to-ts
flow-to-ts [options] <file globs>
anywhen possible and provide a gentle warning
%checks), remove the syntax and provide a forceful warning that the code in question will need a human to convert it manually.
Bug reports for converting Flow to TypeScript should include a link to the playground with an example of a minimal reproducible example of the bug.
Feature requests are welcome.
Please make sure there is a GitHub issue first before creating a pull request except for small things. Also, please sign our Contributor License Agreement.
Pull requests that fix a bug in the conversion code should include one or more test cases and should have 100% diff coverage.
