Add experimental React Native adaptor.

@pie6k thank you so much for the review! I managed to get rid of all untyped imports except DocumentReference that isn't exported. I also released [email protected].

[pie6k]

Seems like DocumentReference is indeed not exported from public API of the package...

@pie6k did you have a chance if It worked? 🤞

Hi!

I'm using typesaurus with firebase(web) package on react-native. It works well.
I don't use react-native-firebase.

However if this pull request will merge, I can't use firebase(web) with react-native.

Can I switch adopter by manually?

for example interface.

import { setAdopter } from "typesaurus"
import * as firebase from 'firebase/app' // web adaptor

setAdopter(firebase.firestore())

@hotchpotch that's terrible news but great timing! I guess I have to figure out how to make them all work together.

It's not possible to change adaptor on the web, but even if I add the ability, your case will break with an error "missing react-native-firebase". So I don't think that's an option.

@pie6k I'm wondering tho, what's the advantages of react-native-firebase over the web firebase package?

Hey, sorry for not testing your PR deeper. I switched to different approach and didn't have time to play with it.

There are quite a lot of advantages of using it over web based lib in React Native
eg.

• firestore uses some sort of native database for offline support in react native firebase
• react native firestore uses native bootstrap code, so you can know if user is logged in in sync way. With 'plain web' solution there is no way to read any persisted data in a sync way. it's useful if you want to make some decisions quickly depending on auth state when starting the app
• it integrates with native authorization methods eg. using app models for showing facebook auth window
• it supports managing native notifications permissions
• support of attaching native views to analytics of firebase
  etc.

I think @firebase/firestore or @react-native-firebase each has pros and const.

• @firebase/firestore is pure JavaScript library. No need native module compile. So @firebase/firestore works well with Expo
• @firebase/firestore is Google official library.
• @react-native-firebase is not Google official library. Don't work with Expo.
  • But It has some advantages than @firebase/firestore.

I'm using @firebase/firestore with react-native (with Expo).

So I would be happy if there was a way to select @firebase/firestore or @react-native-firebase.
However, I don't know how it works...

I looked into about dynamic import with react-native.

Currently (react-native <=0.62) , it is not work yet.

• Dynamic import not working facebook/metro#52
• Optional imports in Metro react-native-community/discussions-and-proposals#120

However, next react-native version 0.63, Dynamic import will probably work.

• add optional dependency support facebook/metro#511 (merged! will release with react-native 0.63)

Example implmention

• native...hotchpotch:react-native-adaptor

Hi!
I'd like to know if you plan on merging this PR still. Using the 6.1.0-alpha.2 works but some typings are incorrect (which I imagine were fixed on 7.0.0 an onwards)
