jsii should allow configuration of source and output directories

[RomainMuller]

Currently, source directories are hard-coded to ['bin', 'lib', 'tests']. It may be desirable to allow configuring this.

We should also allow users to configure their typescript output directory. Some users (#213) may prefer their .js and .d.ts files not to be in the same place.

Oh please! While we're on this... do we actually need jsii to figure out source files? Can we not let tsc discover these itself from tsconfig.json?

I'm asking because right now, running tsc does not have the same effect as running jsii, and it's blocking my experimentations with the new TypeScript project references support (which is promising to improve our compile times by mucho!)

@rix0rrr so you are suggesting that the generated tsconfig.json will include a files section that corresponds to how jsii is using the compiler, correct?

[rix0rrr]

Or "includes" pattern, much like jsii uses internally. tsc can also glob

Any plans on this? I really like tsc to output the files to another folder instead of the lib folder.

[eladb]

No concrete plans but good intentions ;-). Would love a PR for this of course. Just haven’t had a time to prioritize
