BSON.js

BSON.js

A fast, simple BSON parser for Node, available as an addon or as a (slower) pure Javascript variant. The addon is approximately 10x faster than the pure JS version. There are no external dependencies.

Building

In the project directory:

node-waf configure build

Usage

The library automatically loads the addon variant if it is available:

var bson = require('/path/to/lib/bson');

bson.encode({foo: 'bar'});
bson.decode(bson.encode({foo: 'bar'});

To force either the addon or the pure js version, simply require them explicitly:

var bson_pure = require('/path/to/lib/bson_pure'),
    bson_ext  = require('/path/to/lib/bson_ext');

Notes

Portions of the code have been nicked from various places including node-mongodb-native, node-mongodb, and the mongo c driver, though the c/c++ code was rewritten to support more robust error handling. Have a look at /test and /benchmarks for more details.

In my branch of node-mongodb-native I'm seeing a 5-7x increase in performance with the addon variant.
