Questions tagged [mean-stack]

The MEAN stack is a methodology that employs MongoDB, Express, Angular / AngularJS, and Node.js to provide a complete end-to-end system. One of the primary motivations for such a stack is that it is pure JavaScript at all ends. Two different implementations are available: mean.io and mean.js

MEAN (an initialism for Mongo, Express, Angular, Node) stack can be implemented just as LAMP stack is implemented, with or without a specific framework or architecture as the four technologies can be implemented in completely different ways.

A ready-to-go implementation is available at meanjs.org.
