I just finished the graphic interface of my irc client for the school. Now I need to find the part of the library of twisted the way to get message from server. I found https://twisted.readthedocs.io/en/latest/words/... ... is any function to listen to irc server implemented in twisted,

Hello - wonder if someone can point me in the right direction: I am trying to find the right way to model this use case: I have Python-Eve (a flask based app) publishing endpoints for mongoDB. I would like to have a websocket event system to allow people to register for notification when specific endpoints would yield more data.

So when a PUT is performed on the endpoint, it signals that new data is available via the event, or even just pushes the data out to those listening.

sigh ... did anyone reply

sphet: How are you? What you've proposed sounds reasonable enough - but what exactly is your question?

jMyles: Thanks for your time! I guess my question is - where do I start? Currently I have a flask-based app running eve that is being run through twisted via a WSGIResource. I don't know how to add the websocket part along side that, nor the best way to interop between the blocking flask handlers and the async websocket elements.

jMyles: I can't believe I just said "Where do I start?" - the curse of help boards. I actually am farther along than 'starting'.

sphet: :-)

sphet: One way or another, the answer to your question probably involves Autobahn.

jMyles: We're coming from the environment of using buildbot, which uses autobahn and twisted. We would like to use similar technology since it is already installed in our environment and we know a bit about it.

jMyles: That was my suspicion.

sphet: Personally, I prefer a project that I maintain called hendrix.

jMyles: let me quickly take a look.

Here's a demo that shows using hendrix (albeit with Django) with websockets: https://github.com/jMyles/hendrix-demo-django-nyc

(and here's a talk I gave, during which I built the demo above: https://www.youtube.com/watch?v=92VeMkjM1TQ)

jMyles: does it run just as well under Windows as unix? We deploy to unix but develop under windows (long story on that)

I... can't say I'm sure about that. I... think so?

jMyles :)

jMyles: I will gladly look into it. I was thinking of trying to use Autobahn but I became confused about whether I need a WAMP router and crossbar.io and then got lost in understanding what those thingsare.

hendrix uses Autobahn for native websockets (and can use txsockjs for JS websockets / long-polling, but I don't recommend that anymore).

jMyles: Can you give me 5 second WAMP/crossbar router overview?

Do I need to be running crossbar?

sphet: Nope!

Although you might want to for your own reasons.

sphet: If you are going to use hendrix, I suggest starting with tags/3.0.0rc1

That will be released on PyPI within a couple weeks.

great thanks so much for your help

I'm actually interested in any thoughts that anybody in this channel might have about a different issue in hendrix:

(ie, see: https://github.com/hendrix/hendrix/blob/3.0.0rc...)

Basically, I had to write my own tooling to do curve selection (and to set an EC key in PyOpenSSL). Does this stuff belong in twisted instead of hendrix?

sphet: the Autobahn library supports WebSockets *and* WAMP -- they're two different things

WAMP can use WebSockets (or other transports) and does PubSub and RPC. To use WAMP you need a router (crossbar.io is one)

if you're just using plain WebSockets you don't need crossbar.io

meejah: But if I want a pub/sub system I can roll my own I guess.

sphet: you can roll your own, sure, or use WAMP (with crossbar.io for example)

meejah: I need some mechanism for cleints to subscribe to the data and publish the events back.

sounds like a good use-case for publish/subscribe for sore

sure
