No changes to files after running against files containing .extend

[patreeceeo]

Maybe I'm missing something very obvious, but when I use this codemod as described in the README against files using the .extend API, those files remain unchanged.

NPM version: 6.10.2
Node version: v8.12.0
OS: macOS 10.13.6

Would you need any other information?

Thanks for making this!

Seems that the root cause is that I'm using Typescript:

Encountered an error while processing ../resources-ui/src/app/components/Buttons/Button/index.tsx:
Error: Cannot combine flow and typescript plugins.

If I just remove L9 from src/v4/common.js, which adds the flow plugin, it works as expected.

Why is the flow plugin included? Can it be not included by default unless, say, the user passes a --with-flow flag or something?

I can second that the codemod doesn't work with TypeScript, but removing flow fixes this. It would be good to make this plugin optional.

I'm trying to run this against a plain JS codebase with npx, no changes for .extend. If I install the codemods in the project and run with yarn, it works!
