TypeScript 3.8 "import type" is not supported

Do you want to request a feature or report a bug?

Feature request.

What is the current behavior?

Import type are not recognized by metro’s babel version (it uses 7.8.4 instead of 7.9 which supports them).

If the current behavior is a bug, please provide the steps to reproduce and a minimal repository on GitHub that we can yarn install and yarn test.

What is the expected behavior?

Please provide your exact Metro configuration and mention your Metro, node, yarn/npm version and operating system.

Using npm to install metro-react-native-babel-preset (version: 0.59.0).

@WhippetsAintDogs thx for your comment:

I was trying to find out on the repo where metro declares this specific babel version, but it seems that it doesn’t.

It uses ^7.0.0, which probably means that any 7.x.y works. So after updating my own package.json with:

    "@babel/core": "7.9.6",
    "@babel/runtime": "7.9.6",

It worked without any problems… till now 🤔

@Grohden, you’re right. Regenerating metro’s part in my package-lock fixed it.

Thanks !
