Is a binary JSON javascript library available for browsers?

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.


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:
