Hi, I’m writing a simple web app written in HTML + JS that posts data via AJAX to a Cowboy/Plug Elixir server. I want the server to also send unrequested updates to the web client (i.e. messages, notifications…) without Phoenix. Not for any special reason, just that I’d like to know if it’s possib…

Also note that on the client and server you’ll have to roll the following yourself: handling disconnects and reconnects – websockets don’t do this for you automatically handling the websocket process crashing the server and notifying the client. Have the client automatically reestablishing and rec…

You could certainly make it work without Phoenix, but I don’t think it’s worth it. IIRC, Plug doesn’t support installing custom Cowboy handlers, so you’d have to hack a bit around it (I think Phoenix can serve as an example). Then you could install websocket handlers and it would basically work. In…

@sasajuric is correct, you wouldn’t want do that by yourself. You can do even simpler by adding only websockt handler into pure elixir mix project, like this : [image] meh/elixir-socket Socket wrapping for Elixir. Contribute to meh/elixir-socket development by creating an account on Git…

@chrismccord Do you have any plan to split phoenix_channel into a standalone application? Maybe I have same problems with @cfenollosa . A realtime channel is enough for me and I don’t want to import unneeded packages such as ecto, templates and so on.

No, since you need a webserver to make channels work with our default transports (WebSocket and LongPolling). If you don’t want HTML templates or Ecto, no problem: mix phoenix.new my_app --no-ecto --no-html. Problem solved :slight_smile:

@chrismccord does Pheonix has published its data transfer protocol? I’m also planning to use it in one of my application, was worried about this because I will have to write clients for Unity or any other game engine, so depending on a third-party library can be quite challenging
