basalt
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.
NPM Install
npm install basalt
Building
In the project directory enter:
node-gyp configure
Then enter:
node-gyp 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.
Compilation/Build Notes
Currently, this library only builds reliably on Win32.
A Linux build is in the works, and potentially a Mac build as well.
