I'm not sure if this is the best way to handle this. If we do this then we have to remember to not update this dependency in the future. Is there a lightweight alternative to Inquirer that we could use instead?

Yep, there definitely should be, will check later. I think you added the inquirer library over prompt.js #1772
the worst case scenario is that we can bring that piece of code back?

That's right. I think that was my first contribution to Create React App. 😀

I'd like to avoid going back to a custom solution. There was a reason we moved away from that in the first place. I'll look around a bit too and see if I can find a good alternative. I suppose we could also raise an issue with Inquirer if someone hasn't already.

closing this in favor of a smaller package.

@iansu finally found something reasonable:
If we just want Y/n prompts:
https://github.com/enquirer/prompt-confirm
If we want a more inquirer like experience:
http://enquirer.io/

Asking inquirer to use a different Observable implementation is probably a better bet. eslint@5 is using newer versions of inquirer, so it'll come back, anyway.

hmmm. they upgraded from rx-lite (400kb) to rx5 and more recently rx6.
SBoudrias/Inquirer.js#614

@bugzpodder Do you mind opening an issue with Inquirer about reducing their install size? Let's see what they say before we consider replacing the package.

Sure I'll see if i can open a few issues.
From my understanding I think they are set on using rxjs and it probably doesn't make sense for them to switch to another library. SBoudrias/Inquirer.js#614
It is a problem with RxJs itself where it is including src/ in the npm bundle. ReactiveX/rxjs#3334
I assume this will be eventually fixed by rxjs.
I also tested enquirer and its api is mostly identical to inquirer so it might be okay to just switch and deal with it later. There are a few odd UI issues that I can just submit a one-line PR for (eg showing: Do you want to eject: true instead of Do you want to eject: Yes) . but library otherwise is mostly pretty solid.

It looks like RxJS is intentionally publishing src. Let's see if we can get this fixed upstream and if not then we can discuss replacing Inquirer.

The src is about 2.2MB, so its unclear if excluding source will help that much.
