Mind elaborating what this change was for please? I don't really have context, so hard to figure out :)

Ah got it. So questions here:

  • is filename necessary?
  • can we just use preset-typescript instead of both plugin and preset? I believe the preset has the plugin built-in

The change is necessary because preset-react won't work with TS files.

Without the filename I get this error on the Redwood project. You're right about @babel/preset-react - it's not needed

Hey, so I think this will fail when using .js files, because preset-typescript will only parse jsx when https://babeljs.io/docs/babel-preset-typescript#istsx is forced to true. I'm not 100% sure because of how the merge is being used.

My suggestion here:

  • keep babel/preset-react
  • also include preset-typescript
  • Add a few more unit tests that cover the usecases in this PR

I've tested both ts and js projects manually, everything's working. I'll add unit tests.

Ahhh... maybe because the filename has .tsx in it, it automatically enables JSX parsing!

Do you have an idea what tests to write? Merge two files and test that the merged file has contents of both files? I.e.

// file1.ts
const varA = "such redwood"
const sharedArray = [1, 2]
// file2.ts
const varB = "so framework"
const sharedArray = [3, 5]
// merged.ts
const varA = "such redwood"
const varB = "so framework"
const sharedArray = [1, 2, 3, 5]
// ...test.js
expect(mergedFile.toString()).to.include('varA = "such redwood"')
// test other content

I think the key thing to check would be that one of the files being merged having JSX in it.

Maybe the easiest way to test it would be to take a snippet of what you're actually merging and just have it as a test. The primary motivation here would be to prevent regression :)

presets: ['@babel/preset-react'],
filename: 'merged.tsx', // required to prevent babel error. The .tsx is relevant
presets: ['@babel/preset-typescript'],
})
}
