smaller alternative to RxJS?

[mheiber]

Thanks for your library!

I noticed that 27% of the package size is RxJS:

We're trying to keep package sizes small to reduce download times for users.

@react-native-community/rxjs seems seems to be 1/10th the size. A more drastic change would be using something like xstream.

This would be great. ESLint is around 36 MB on my machine – almost half of that is rxjs (via inquirer).

Edit: Just found ESLint is getting rid of inquirer.js because of this: eslint/eslint#13254

Agreed on this. I've yet to find a replacement but I think it's totally worth dropping it eventually.

FWIW, the repo contains beta versions of a fully reimplemented version of Inquirer without rxjs (see #692)

It's not complete, but most prompts are functional and deployed to npm already. There's just not any top-level Inquirer.js release offering the question list API (it goes like await checkbox({ ... }))

You might be interested in trying the beta versions, or helping out 🙏 with refactoring missing prompts.

Nice to hear that!

Can you share a little more info like a PR/branch/tag where the rxjs removal is implemented? I can't find it anywhere.

I haven't used rxjs myself, but the number of files it ships is insane :/ And imagine on a big project where the package manager cannot deduplicate rxjs, the effect is even bigger.

Of course, this is on the master branch, but in different section of the monorepo. Inside the packages/** root, every folder except inquirer are new prompts implemented without the rxjs dependency.

They're not all documented yet, but they all work in similar fashion to https://github.com/SBoudrias/Inquirer.js/tree/master/packages/confirm

Ah, I was looking at this:

Inquirer.js/packages/inquirer/package.json

Line 50 in a1da6cf

"rxjs": "^7.2.0",

Very promising, looking forward to the removal of rxjs!

The new Inquirer is now out and stable (and can boast of having MUCH smaller size). So I'll close this ticket as I don't intend to modify the old one aside from basic maintenance.
