triplit VS RxDB

If you want to try that out, we use Sqlite in our server implementation so you can see an example there: https://github.com/aspen-cloud/triplit/blob/main/packages/se...

Your app might not need it but if you want partial replication or relational querying in addition to offline-first syncing then check out https://github.com/aspen-cloud/triplit (disclaimer: I'm working on this)

I'm currently writing a very similar article about "full-stack databases" which highlights the same pattern where many apps end recreating the logic of our backend and database in the frontend client code. The solution we're promoting is to choose a database that can run on both the server and in the client and then sync between them.

The reason we aren't using Sqlite for our product is because Sql is frankly not the right tool for querying data for an application. It doesn't easily map to the data-structures you want in your client code and nearly all SQL databases have no way to subscribe to changes to a query without polling the query repeatedly.

So if you like the idea of having a complete database on your client but also want deep integration with Typescript/Javascript check out what we're building at https://github.com/aspen-cloud/triplit

I'm interested in this problem also!

I think there is a large overlap with projects that market/focus on offline-first experiences.

AFAIK this problem can be solved by:

1) Considering a client-side copy of the database that gets synced with the remote DB. This is an approach [PowerSync](https://www.powersync.com/) and [ElectricSql](https://electric-sql.com/) and [rxdb](https://rxdb.info/) take!

Hey, after I posted that, I went and gave a second look online to see if I could find something that would allow me to develop a local-first app with offline persistence and syncing capabilities.

I ended up finding some possibilities out there that could potentially help me build stuff. One of them is RxDB [1], which offers WebRTC syncing - you'd still need a signaling server, I suppose, but all sensitive information could be synced E2E-encrypted via WebRTC.

Then there's CRDT's [2], which is a universe that turned out to have multiple possibilities that match (at least partially) my needs. In particular, the next thing I want to take a look at is cr-sqlite [3], which might be just thing I needed to kick-off some side-projects.

I'm posting here cause I just found some hope of not needing to build a traditional client-server app and having to deal with all the hassle involved in securing a server (and with fear that my efforts could be not good enough), and I thought someone else could benefit from getting to know these things.

About a year ago, I discovered a cool offline-first framework called RxDB. Initially, I thought that on the frontend side, this was exactly what I had been searching for over the past years. After tinkering around and even using it in production for some time, I realized that it wasn't well-suited for my intended use. RxDB was initially created as an RxJS layer for PouchDB with a server replication interface. Over time, other storage types besides PouchDB were introduced (e.g., IndexedDB, SQLite) and the replication interface became more sophisticated. The replication interface is really cool and exactly what I wanted. The biggest problem I have with RxDB is that it is so tightly coupled with RxJS. While RxJS is technically very powerful, it offers a dreadful developer experience. It's really hard to understand at first and integrating it into an existing codebase, which isn't using RxJS, is tedious.

Congrats to the team. Once I’ve tried https://rxdb.info/ and it wasn’t funny at all to do the remote replication (PG) and to deal with conflicts. I do need to check this out!
