Is a binary JSON javascript library available for browsers?
In order for efficient server side parsing I am looking into a BSON solution directly for the browser javascript environment. The idea is to utilize the entire ASCII space by means of binary websockets. Any suggestions?
(Any nodejs suggesti开发者_JS百科ons are welcome as well)

For what it's worth, it appears that the MongoDB team now have a supported Javascript BSON project:
https://github.com/mongodb/js-bson
I'm no expert with the library, but the project claims to work in both Node and the browser. Below is a modified sample from their site:
<head>
<!-- Originally https://raw.github.com/mongodb/js-bson/master/browser_build/bson.js -->
<!-- But downloaded and hosted locally -->
<script src="./bson.js"></script>
</head>
<body onload="start();">
<script>
function start() {
var BSON = bson().BSON;
var Long = bson().Long;
var doc = {
oid: bson().ObjectID(),
long: Long.fromNumber(100),
date: new Date(),
string: "js-bson sample",
obj: {
string: "Object within an object"
}
}
console.log("doc %o", doc);
// Serialize a document
var data = BSON.serialize(doc, false, true, false);
console.log("data %o", data);
// De serialize it again
var doc_2 = BSON.deserialize(data);
console.log("doc_2 %o", doc_2);
}
</script>
</body>
Below are my results in Chrome:
This might be incomplete but the goal of the project line up with what you want: https://github.com/muhmi/javascript-bson It doesn't look like that encodes directly to typed arrays which would be the most useful for sending over WebSocket.
