MongoDB and Node.js at 10gen

Apr 25 • Posted 2 years ago

With their strong roots in JavaScript, Node.js and MongoDB have always been a natural fit, and the Node.js community has embraced MongoDB with a number of open source projects. To support the community’s efforts, 10gen is happy to announce that the MongoDB Node.js driver will join the existing set of 12 officially supported drivers for MongoDB.

The Node.js driver was born out of necessity. Christian Kvalheim started using Node.js in early 2010. He had heard good things about MongoDB but was disappointed to discover that no native driver had yet been developed. So, he got to work. Over the past two years, Christian has done amazing work in his driver, and it has matured through the contributions of a large community and the rigors of production. For some time now, the driver has been on par with 10gen’s officially supported MongoDB drivers.  So we were naturally thrilled to welcome Christian full time at 10gen to continue his work on the Node.js driver.

In version 2.1, MongoDB is introducing a new aggregation framework that will make it much easier to obtain the kind of results SQL group-by is used for, without having to write custom JavaScript.
