Actually, the long term plan is to move away from pouchdb. Before the last major release [1] I decided to make RxDB useable with other frontend/backend databases but then found out that I first should refactor some pain points.

That’s great to hear! Are you pubkey? If so you should put that in your profile!

I hope you know that I think RxDB is a great lib and going in a good direction! I recommended it to the Supabase team a couple weeks ago. I am less long PouchDB, it feels like an old generation of this tech and not the best way to solve these problems in 2020.

I updated my profile. I do not know supabase, is it similar to hasura? They spend quite some effort [1] to make the RxDB graphql replication working with their backend. Maybe supabase can use a similar wrapper over GraphQL.

Cool! I was just thinking that RxDB + Hasura would be pretty nifty for an offline-first MVP and here the legwork has already been done :)

Hey there, I'm the CEO of Supabase - we're pretty new (YC S20).

We've been considering using RxDB. I'm especially excited about the changes you have planned for the next version. I'd love to chat whenever you have time - my email is in my profile.

Ah, nice.

Does it work with AppSync? It seems to me that Amplify/DataStore is a product like RxDB, and they use AppSync as backend.

Edit: I just saw it seems to integrate custom GraphQL, so it probably a direct competitor to DataStore in that regard.

No it does not work with appsync, but it could be hacked into doing that by modifiing the GraphQL plugin. There would be a huge value in replacing the aws datastore mainly because of its missing basic features like complex queries or queries with sort params.

Ah good to know you already looked into that :D

Thanks for the info!

Yes I did :D . I wrote a full master thesis about the differences and tradeoffs of these "realtime" databases.

Well, DataStore is rather new AND AWS specific, so I simply assumed you wouldn't even care.

but good to know. Reminds me of the fact that I still have to write mine, lol

Is it available online? Sounds interesting.

I also would be highly interested in picking up RxDB if it can integration with either AppSync or PostgreSQL. I guess with the later- would it be possible to use RxDB with the GraphQL plugin against Postgraphile? Feels like a lot of 'magic', but it would be great something like this just worked.
