index.ts barrel files in the codebase?

Having single index.ts barrel files in each directory might help others to understand the codebase a bit better, and remove a lot of extra files that are currently one-off barrels (for instance compiler/class.ts, compiler/common.ts, compiler/decorator.ts, etc.)

It would also be a bit more idiomatic in that you could import directly from a directory, such as:

import { CallExpression } from './compiler';

and:

export * from './compiler';

Thoughts?

@gregjacobs I ended up rolling this into a library. I’ll make the repo public soon, but you can try it out now if you’re interested:

# install
npm install -g barrel-maintainer
# view the help
barrel-maintainer -h
# run it on a project
barrel-maintainer src

That will run in the background and watch the files for any changes. I still need to make a few improvements before making that public.

Obviously, make sure to have the ability to easily restore the project back to normal based on any changes you make.

I was thinking about a library that does it, but yeah this is such a simple script to write and it would be more flexible if people maintained it themselves. I’ll add it to the docs. Thanks!

Also, these barrel files are so much better. Really helped reduce the noise in the code.
