RFC .projenrc.ts support about projen HOT 10 CLOSED

Projenrc in typescript is now supported via:

projen new typescript --projenrc-ts

from projen.

I am having seconds thoughts here. Let's keep it in the backlog for now and see how far we can get with JavaScript.

Yes, why not?

This will also require ts-node

from projen.

Maybe npx ts-node as it is in CDK?

from projen.

That would mean that every time you run projen ts-node will be executed or it has to be installed globally (which means that which ts-node should just work.

This is related to perhaps adding support for other languages. Would be nice to be able to also author projenrc in python for example, which will also have some ambient prerequisites.

I am open to doing that: we can auto-discover the .projenrc file type based on its extension and then require the user to have the "runtime" pre-installed in their system.

There's also https://github.com/antfu/esno, which uses esbuild to transpile on the fly. I use it with CDK and am pretty happy with it.

Maybe a file like cdk.json would help here to make it customizable?

from projen.

esbuild does not perform type checking as far as I know, Correct?

from projen.

Exactly, it just executes the code. Maybe that's not what you want in this scenario.
