Javascript + C++ BSON parser

This BSON parser is primarily meant for usage with the mongodb node.js driver. However thanks to such wonderful tools at onejs we are able to package up a BSON parser that will work in the browser aswell. The current build is located in the browser_build/bson.js file.

A simple example on how to use it

<head>
  <script src="https://raw.github.com/mongodb/js-bson/master/browser_build/bson.js">
  </script>
</head>
<body onload="start();">
<script>
  function start() {
    var BSON = bson().BSON;
    var Long = bson().Long;

    var doc = {long: Long.fromNumber(100)}

    // Serialize a document
    var data = BSON.serialize(doc, false, true, false);
    // De serialize it again
    var doc_2 = BSON.deserialize(data);
  }
</script>
</body>

It's got two simple methods to use in your application.

BSON.serialize(object, checkKeys, asBuffer, serializeFunctions)
- @param {Object} object the Javascript object to serialize.
- @param {Boolean} checkKeys the serializer will check if keys are valid.
- @param {Boolean} asBuffer return the serialized object as a Buffer object (ignore).
- @param {Boolean} serializeFunctions serialize the javascript functions (default:false)
- @return {TypedArray/Array} returns a TypedArray or Array depending on what your browser supports
BSON.deserialize(buffer, options, isArray)
- Options
  - evalFunctions {Boolean, default:false}, evaluate functions in the BSON document scoped to the object deserialized.
  - cacheFunctions {Boolean, default:false}, cache evaluated functions for reuse.
  - cacheFunctionsCrc32 {Boolean, default:false}, use a crc32 code for caching, otherwise use the string of the function.
- @param {TypedArray/Array} a TypedArray/Array containing the BSON data
- @param {Object} [options] additional options used for the deserialization.
- @param {Boolean} [isArray] ignore used for recursive parsing.
- @return {Object} returns the deserialized Javascript Object.
