with the original ZWS spec ws frames are type-tagged with a single character code.
Since the protocol does now assume a binary-safe link, we could use a normal binary int field to represent the ws frame tag. This would for instance allow encoding of bit fields, for instance the ZMQ_MORE flag.
Options I see is:
My personal preference would be the latter. It is well specified, implementation is well understood (all of google protobuf breaks if this breaks), and it is extensible with respect to the size of the value, while being a single byte in the common case.
On varint encoding:

http://stackoverflow.com/questions/19758270/read-varint-from-linux-sockets
the nice part: https://github.com/dcodeIO/ByteBuffer.js/wiki/API already takes care of varint encoding, and base64 if required, so not much to do. Meaning: if we use ByteBuffer.js to encode the ws frames, support is outsourced.
Hello there,
I found this project to be particularly interesting and I would like to know more about its current state of development. The README says "Both JSMQ and NetMQ WebSockets are beta at the moment and the API and protocol will probably changed.", and the last commit appears to be 4 months ago. What needs to be done to bring the code to a stable release? Is there a road map formulated somewhere?
Thank you for your time.

Now I have a ZMQ server that is written in PHP. How can JSMQ work with it? Does it need a websocket server? Please help!
@somdoron
It seems I can't send large strings like the dom of an HTML page through jsmq, I've tried multiple things, like StringToUint8Array function, slicing the array into pieces which didn't work also...
Any ideas how we can achieve that ??
I think any framing/encoding of zeromq frames over websocket transports MUST handle frames binary transparent.
This is a requirement of using code. If the protocol layer can use a particular ws connection in binary-safe mode or not MUST not impact using code.
I think if JSMQ is not to be binary-safe, we could just as well encode a zeromq msg as a JSON object and be done with it. Actually base64 encoding non-binary-safe frames and tagging them as encoded, then sending the whole zmsg_t as a JSON object is an alternative option for the protocol. Not elegant, but workable.
we might want to think through this issue as far as any frame-level support might be required.
While I'm still clueless on the issue, it seems frame-level support might make sense, like in this example: https://github.com/tavendo/AutobahnPython/tree/master/examples/twisted/websocket/auth_persona
I'd see two different scenarios which might be combined eventually:
