Don't publish tests or TypeScript source files

[midgleyc]

Looking at unpkg, you're currently publishing the tests, among other files. I don't think this is necessary.

This PR limits the published files to those in browser, es6, lib, package.json, LICENSE and README.md (the last three are implicit with how files works). I think this should cover everything comment-parser needs to work.

This saves about 180kB, or about half the size of the package.

Sorry for the late response. it does make sense, but what if someone is already relying on *.ts delivered with the package?
Maybe, moving forward, the better option would be to export different tiny packages like comment-parser-{es6,browser,cjs}

[midgleyc]

I don't think someone can be relying on *.ts files -- you get the types from .d.ts, and I don't think you can import a .ts file inside a .ts file (you could from javascript, but the TypeScript files aren't valid JavaScript). exports in your package.json directs to the es6 and cjs folders, additionally.

The easiest way to find out for sure is to post an update, then check for incoming bug reports.

Splitting the package would be nice, and would mean that users interested in cjs don't need to also download es6 and browser -- even fewer bytes downloaded.

nah, there were a couple of bad episodes when I was breaking other tools dependent on the parser, and I am not feeling confident making any assumptions. I will look into how to automate smaller packages publishing, thanks for suggesting this kind of improvement.

On other hand, I am not completely sure this is something to be solved in comment-parser. Whoever uses it will do the bundling/tree-shaking/etc the way they need, unless it's some rare pull-in-runtime case

[midgleyc]

On the node side, when I do an npm install I get everything in node_modules, together with all the dependencies those libraries have. If I npm install a library that includes your library, I get all the code you publish, no matter what build steps my direct dependent does.

And when I build a docker container from scratch (or in CI, when running tests) I get those files.

I wouldn't expect these files to make it through to a browser endpoint. But they're going to get pulled down when running test on or building something server-side. And I don't think they need to be.

[syavorsky]

I see. It's arguable that 180kB improves the Build/CI time, but baking specific node/browser/es packages may still make sense for someone. I will put it on my stack.

[midgleyc]

Certainly, I don't expect removing files in just this package to be noticeable -- but if all my dependencies are packaging 180kB they don't need to, that quickly adds up.

Thanks for engaging here!

I also just noticed through the usage of https://github.com/duniul/clean-modules that comment-parser is still bundling lots of redundant files into end users node_modules folder.

Can we get this PR merged?
