A 225K gzipped .wasm file download for a client-side state management and persisistence layer is not great. It is competitive with some similar solutions, but still a lot for any web app's performance budget
The release build is 100k brotli I believe. It’s possible this site is using the dev binary.
> Dealing with a global database brings in much complexity that is not essential to the subject matter of this article, which will wait for another piece. Excellent write. It would be great to know why CockroachDB failed your needs.
This stack reminds me of Meteor, which came out nearly a decade ago(!). https://meteor.com It never really took off in the mainstream - I think because it was before many developers really trusted JS on the server, and a "full stack" framework is quite a big commitment for a team to shift to. Also most CRUD apps don't need real time collab. I remember being amazed when changes were instantly propagated between my pho…
I'm interested how this stacks against Phoenix Channels + Presence.
Yes, it would be great if someone with this experience can chime in, especially since Phoenix has CRDTs built-in.
- WebSocket (and Phoenix Channel) is just a communication method. To maintain consistency and resolve conflict, you need something like Replicache.
- CRDTs are more suitable for p2p scenario while Replicache works better for client-server apps.
- Phoenix's Presence is built with CRDT but it's just a single feature, not a general CRDT toolkit.

Really interesting...you can build a similar (websocket/db backed) app with LiveView out of the box, no? Any idea how well that'd hold up against this solution?
That being said you can totally implement collab without CRDTs and if you don't particularly need offline it should be easier.
I'm really glad to see an article like this. I've worked in the space for a while (Fluid Framework) and there's a growing number of libraries addressing realtime collab. One of the key things that many folks miss is that building a collaborative app with real time coauthoring is tricky. Setting up a websocket and hoping for the best won't work. The libraries are also not functionally equivalent. Some use OT, some use…
I know of one big company using it extensively, hundreds of millions of messages a day! :)
Also, integrations use polling: https://github.com/FastComments/fastcomments-integrations/tr...
The integrations work kind of like DB slave replication. They do an initial sync and then maintain state via the event stream.
Very nice writeup! However, the example did not fully work for me. I could perform CRUD on a single tab, but opening the list in multiple tabs did not replicate the list or actions. Seeing this in the console: [Error] Could not connect to the server. [Error] Fetch API cannot load https://damp-fire-554.fly.dev/replicache-pull?list_id=kx1I-gXPWwOxU9teRUJ_c due to access control checks. [Error] Failed to load resource:…

DerbyJS and ShareDB/Racer are meant to go together. I know of one big company using it extensively, hundreds of millions of messages a day! :)
Like a Google Docs kind of thing or w?
