How to connect to a channel?

[mastoj]

There is no sample on connecting to a channel and I struggle. I thought it would just be to send som data that looks like:

{
    "Topic": "the-topic",
    "Payload": { ... payload ... }
}

But my handler won't trigger. I do see that I manage to join.

I had the same trouble, You're also missing a Ref: string field. Also depending on whether you're using the default serializer or not you might need to check the casing of the members.

Sorry, for lack of the documentations - channels are still bit experimental, so I don't want to push into people them too hard at the moment.

As @huwmanatee mentioned, it seems the problem here is missing Ref field.

No need to excuse yourself. I can maybe push some docs up if I ever get the time to play with it again.

What does the ref field do? I still struggle to get it working. Is there a good example of a fable client somewhere I can look at?

[sgoguen]

I was able to trigger the handler in the JavaScript console with the following:

var exampleSocket = new WebSocket("ws://localhost:8085/channel");
exampleSocket.send(JSON.stringify({ Topic: 'topic', Ref: 1, Payload: 'Test' }));

I've also added some very basic client code to channels in a feature branch here: https://github.com/sgoguen/Saturn/tree/add-channel-client-example/sample/ChannelsSample

@Krzysztof-Cieslak - What criteria do you have for closing this ticket? A Fable client?

There's an example of using channels here as well: https://github.com/CompositionalIT/safe-sockets

Ok, given there are some examples linked above that are working, I'll close this issue. Obviously, we still miss documentation on the topic, but hopefully, we'll be able to solve it given that I've modernized all the infrastructure about Saturn documentation.
