Shouldn't postal.channel() implement the Singleton pattern?

[estaylorco]

I'm using postal.request-response and I noticed from the PostalJS code base that postal.channel() returns a new ChannelDefinition every time.

It seems to me that, if a ChannelDefinition exists for a particular channel, it should just return that instance. I mean, what is the meaning of the following:

const loginChannel1 = postal.channel('login');
const loginChannel2 = postal.channel('login');

Should we be able to have two distinct instances of a definition over the same channel?

This is interfering with postalRR because it would appear that both requester and responder need to have access to the same instance of ChannelDefinition, which defeats the purpose. Responders and requesters are almost invariably going to exist in different parts of the application.

Or am I missing something here?

Thank you.

2021 still facing issue any update over here ?

I don't see how this is an issue. Each channelDefiniton has access to the same Bus. And sbscribers are attached to that bus: https://github.com/postaljs/postal.js/blob/master/src/ChannelDefinition.js#L9

Can you provide a working example of where postal is not working as it should?
