Hi, we have an NextJS Frontend Application which is basically React. Now we would like to use a Phoenix App as a Service for some Live data. But we only need the JSON no HTML. Is Phoenix LiveView a good fit for this, or should we go with the low-level Phoenix Channels. In comparison, I think that …

I would go with channels, yes. I don’t know if they are low level (I would say websockets are rather low-level, but not channels), but they are very easy to use, so low level or not they are a great tool if you want to push/stream data from the backend.

Channels could work. Have you considered using BERT instead of JSON? Sending data on the Elixir side would use :erlang.binary_to_term/1, which is fast. Then you could use Bert.js on the front end to decode into JS objects. Although it is admittedly a pretty dependency heavy lib.

BERT do not support maps, as it was created before OTP17 which added maps. On the other hand I am working (when I find some time) on ERNIE which is “next gen” implementation of BERT.

My main concern is about the features that LiveView is offering besides HTML sync and event passing (which for my use-case aren’t important) but it seems that there are also other important features on top of plain Channels.

Thank you, I’ve considered BERT. But it does not make much sense when you have a heterogenous environment with different technologies.

To me it looks like this library has no dependencies at all (besides the test lib for dev). https://github.com/ElixiumNetwork/bert-elixir/blob/master/package.json

Hey there. I actually think it’s an idea with a lot of potential and use-cases that could be supported either in LiveView or as a separate library. Being able to use whole React ecosystem while keeping the state in sync with your GenServers (or other abstraction) is something that we already exper…

Cool! I think this is what I had in mind! Update @methyl After watching your screencast. I am sure it’s exactly what I had in mind :slight_smile:

This looks is amazing, I would love to help polish LiveData and get it published on hex! Exactly the kind of middle ground I am looking for - a lower level state abstraction than LiveView, but something a bit higher level than just channels. I have had the exact mental model of redux <-phoenix-ch…

Ah, hadn’t realized it was so out of date. Love the name.
