Mean Technology

Mean Stack refers to a technology stack that allows a complete web application to be developed in a single language, Javascript!

• Mongo DB is a highly scalable NoSQL Database that allows data to be stored
• Express is a javascript library, installed into the node server, that makes it simple to receive and process API requests
• Angular is google's framework for developing highly interactive single page applications that run in a browser or can be wrapped as mobile apps
• NodeJS provides a web server that can host our application and serve our API requests.

Taken together they provide a 100% free and open source stack including the presentation, application server and database server, everything you need to build a complete system. Traditionally a full stack developer would need to learn separate languages for each of these tiers, MEAN Stack allows developers create full system, simply using plain old javascript!
