porting from a backbone app
I currently have a fullblown backbone app. How would I go about integrating Swarm while keeping most of the app intact? Could swarm for instance be used (with some modification to my app) to replace Backbone.sync?
BTW: backend is on Node (Loopback which sits on top of regular Express)
Hi! Swarm was modeled along the lines of Backbone, so the semantics is similar. Still, Swarm is far from being a drop-in replacement. In your case, there is no server-side support (Loopback has no Swarm server on their side). It is still possible to run Swarm alongside backbone, in case you run your own server-side instance.
Currently highly customizing Loopback to update model instances (of 1 particular model) using events in an eventsourcing architecture. This feels a bit similar to how Swarm updates things if I'm not mistaken? Cheers
Exactly. We call it "partially ordered log of immutable events", but "event sourcing" is also a very correct description of what is happening.
By the way, you may play with the Backbone adapter: https://github.com/swarmjs/swarm/commit/a71819cbb4907e5af0628f22953a6f900c88b7b0 Very preliminary, please share any thoughts.
Looks like a good start, may have a try / poc soonish.
As a general question: since I'm currently implementing an eventsource solution (probably using Kafka as eventsource, although actively considering SSDB at the moment as a poor man's alternative), I can't help but notice the overlap in general architecture: i.e.: writing to a tail of a log, which is consumed at some time, etc.
Considering this, may I suggest looking at the following usecases if you haven't done so already?
- being able to replay the eventsource/log
- being able to have multiple consumers on the log, which each save their offset marking up to which operation they have processed
- being able to partition the log (some custom json.property or function return value), which would allow for client orchestrated sharding
I feel these would be awesome features, which might nicely fit/extend what Swarm wants to be. Thoughts?
