FR: Configure tsx in tsconfig.json

[mikestopcontinues]

ts-node supports the following:

{
  "compilerOptions": {...},
  "ts-node": {
    "compilerOptions": {...},
    "require": [
      "dotenv-flow/config"
    ]
  }
}

In my monorepo, this makes it really easy to keep config out of CLI args. In particular, having access to require makes all my scripts draw env-vars properly with minimum fuss.

I'd like to be able to do the same thing with tsx. I saw a previous ticket where you expose --require, though it's undocumented in the CLI help text. I'm not against using it for the time being, but for dozens of scripts, it's overkill to insert it everywhere.

Thanks for such an awesome project!

tsx is a wrapper around Node.js, so it doesn't actually expose --require. It just passes all arguments through to Node.js.

Seeing as dotenv-flow/config is a runtime requirement, why not just import it at the top of the entry-files?

You can also add it via NODE_OPTIONS env var by creating a caller script entry:

{
	"scripts": {
		"dotenv-run": "NODE_OPTIONS='--require dotenv-flow/config' npm run",
		...
	}
}

and run scripts via:

npm run dotenv-run -- <script name>

In terms of configuration, I would like to align more closely with Node.js than ts-node. I'm also very hesitant to add a configuration file as it sets a precedent to justify further configuration to be added (and therefore more complexity).

The main benefit to me is that all scripts I write across my monorepo automatically benefit from the config, rather than requiring boilerplate in the form of import statements or cli args.

That said, I do understand wanting to keep your surface area small. So I'd consider this issue resolved.

Perhaps I should write a script that merely wraps tsx with my preferred args, and use that across my repo. At present, I just updated all my npm scripts with tsx --require etc. Doesn't help with running arbitrary scripts, but it's good enough for now.

This feature is required for my situation. I am detecting my .env based on branch/function so I need to require one ts file every time in my script and that is not good. I hope this feature will release soon...

If you think of tsx as an alias to node, you'll realize there's plenty of other solutions. Try investigation solutions that are designed for Node.js.
