Scan upwards for tsdx.config.js

[selbekk]

Current Behavior

If used in a mono-repo, and you have a top-level tsdx.config.js file, you have to create another tsdx.config.js per package, which basically just re-exports the top-level tsdx.config.js file.

Desired Behavior

It would be great to scan for a tsdx.config.js all the way up to the call-site, and using the first one found.

Suggested Solution

The find-up package seems pretty popular for this kind of work. We would have to change this file:

https://github.com/palmerhq/tsdx/blob/master/src/constants.ts#L11

to use the find-up package.

Who does this impact? Who is this for?

This is for mono-repo users.

Describe alternatives you've considered

Right now I have just created a new tsdx.config.js file per package. It's a pain and just pure dead boilerplate code. I'd love to skip it.

Need to think about this. Seems like a good idea. One issue thing to remember though is that you are gonna have to do a similar re-exporting anyways with tsconfigs. I wonder if it we would want to go a bit further and make tsdx more monorepo aware. Perhaps we add a create subpackage command instead so that users don't need to deal with the tsconfig or tsdx nonsense.

Maybe we make this quite opinionated too. Such as...

tsdx create myproj
# choose a template...
vanilla
react
monorepo
monorepo-package-vanilla
monorepo-package-react

I'm all for making TSDX mono-repo aware, but I think there's some work being done to this already (this repo and #127 specifically).

You don't have to do the re-exporting with tsconfig actually - they already do the same find-up approach iirc.

@selbekk TIL about find up. I think you still usually need to do it though if the sub packages reference each other because you'll need to mess around with tsconfig.paths IIRC

hm - perhaps, haven't ran into that one yet. Right now we're just using yarn workspaces to reference other projects inside the same monorepo.

Anyways - it'd be great to have monorepo support built in - especially the bootstrapping part. :)
