es6 promise v.s. whenjs: progress

[joggienl]

Even though not in the official Promise A+ spec, whenjs has (deprecated!) support for progress like results trough calling notify.

Are there plans to improve this behaviour?

I currently have a use case for using progressive results. But if you set the Connection options to use_es6_promises things break:

autobahn-js/lib/session.js

Line 686 in 10797c7

d.notify(result);

.

I have a specific RPC which I need to call with {receive_progress: true}. It will throw an error on this line.

I'm not sure yet what would be a better way to be able to do progressive results (it is part of the WAMP spec after all). Curious to know I've you have any idea on this already. I don't think it is wise to wait until whenjs drops this from their lib ;-)

rxjs observables would be ideal for progressive call results!
I have a use case for progressive results too, and it would be great when they would be implemented with observables instead of with promises.

progressive results RPC do work and are tested in our CI: https://github.com/crossbario/autobahn-js/blob/master/test/test_rpc_progress.js
