Support *FbtEnum.ts files

Stacked on #2 (needed the automatic external detection)

Currently you cannot have .ts files as enums and you get this error

node:internal/modules/esm/get_format:218
  throw new ERR_UNKNOWN_FILE_EXTENSION(ext, filepath);
        ^

TypeError [ERR_UNKNOWN_FILE_EXTENSION]: Unknown file extension ".ts" for /Users/alex/dev/fbt/example/src/example/Example$FbtEnum.ts

I'm not sure the approach I've taken here is optimal, we could potentially use ts-node or esbuild-register but didn't have much luck with using them in an ESM environment.

Now every enum file is transpiled using TS regardless of the extension, it might be wiser to only transpile .tsx? files. I can update to do that if you think it's a good idea

Did you try --experimental-strip-types? See https://nodejs.org/en/learn/typescript/run-natively

I do not mind that it's experimental, since it won't be experimental for too long.

Otherwise, I would much prefer to use Babel to strip TypeScript syntax instead of typescript because the typescript package is large and we are already using it in other places like for common strings: https://github.com/nkzw-tech/fbtee/blob/main/packages/babel-plugin-fbtee/src/bin/FbtCollector.tsx#L65-L88

see above

No, but AFAICT we cannot enable a node.js flag without manually spawning a new process (or require consumers to pass a flag). But maybe I'm missing something?

Makes sense to use Babel instead of TS though. Updated the PR!

We should totally be in control of how the bin files are invoked, see https://github.com/nkzw-tech/athena-crisis/blob/main/codegen/generate-actions.tsx#L1C1-L2C1

I assume you have to make the changes to the src file, pnpm build and then see if it works or not. Do you mind trying?

[alexandernanberg]

TIL!

From what I can tell it works great. There is a warning logged when running the command that it's experimental but no big deal!

[cpojer]

Just add --no-warnings. Since it's fbtee's cli, that's fine.

[alexandernanberg]

Done! 👍

So elegant. Thank you!
