Question

I’m going to develop a pushing server (HTML5 WebSocket/Polling) and in order to reduce the size of packets (that presents in JSON format) I want to do something like this with packets:

[["id", "username", "password"], [1, "afshin", "123"], [2, "barak", "meme"]]

Instead of clear JSON format like:

[{"id": 1, "username": "afshin", "password": "123"}, {"id": 2, "username": "barak", "password": "meme"}]

Exactly, I want to prevent sending contract properties in each object.

So, I want to know is there any library for doing this (or something like)? I have C# on server and JavaScript on clients.

JSON DB or RJSON should be exactly what you’re looking for. You’ll most likely have to implement serializers/deserializers yourself (RJSON is already implemented in JS though).

As for compressing pure JSON, I think you could bypass the “keys are needed” rule by wrapping all your data in a single object entry:

{"data" : [["id", "username", "password"], [1, "afshin", "123"], [2, "barak", "meme"]]}
