Clojurians Log v2

I might consider migration from SSE to websockets in our yada app. Any examples? Last time I checked it wasn't very easy like SSE

It's easy enough, I've done it. It's more like you leave yada altogether. It's one function call to aleph as I remember

alright, I'll try using this example. https://github.com/ztellman/aleph/blob/master/examples/src/aleph/examples/websocket.clj

no public yada examples I guess?

I think there's one in edge

https://github.com/juxt/edge/blob/392fa203d3dfd6c1a245f22665c6b5c1e751014b/examples/phonebook-graphql/src/edge/phonebook/graphql.clj#L100

https://github.com/juxt/edge/blob/master/examples/main/src/edge/yada/graphql_ws.clj

Yes, that's it - it's a websocket that feeds graphql subscription notifications to apollo's graphql client

cool, thanks!

We did get it working and it was quite nice that we didn't have to build very much to do it - manifold provides much of the additional functionality that lacinia needs

sorry about the state of the code - it was written before I integrated clj-kondo into my emacs!!

no worries 😉

trying to run the example:

$ ../../bin/rebel -A:dev
[Edge] Starting development environment, please wait…
[Rebel readline] Type :repl/help for online help info
[Edge] Loading Clojure code, please wait...
[Edge] Failed to require dev. Falling back to `user`.
[Edge] Make sure to supply `-A:dev` when running `../bin/rebel`.
user=>

the thing I'm trying to find out is if I have to do anything special to make websockets work with yada. right now I'm getting:

ERR_DISALLOWED_URL_SCHEME

websockets are orthogonal to yada - it's a different protocol, piggybacked on an HTTP connection (which is useful, because you can authenticate first before upgrading the protocol).

you could try a simple aleph server, get that working, then integrate with your yada-based system

alrighty, thanks

something worked!

nice! 🙂
