Summary
The MEAN stack, defined
The MEAN stack is a software stack—that is, a set of the technology layers that make up a modern application—that’s built entirely in JavaScript. MEAN represents the arrival of JavaScript as a “full-stack development” language, running everything in an application from front end to back end. Each of the initials in MEAN stands for a component in the stack:
- MongoDB: A database server that is queried using JSON (JavaScript Object Notation) and that stores data structures in a binary JSON format
- Express: A server-side JavaScript framework
- Angular: A client-side JavaScript framework
- Node.js: A JavaScript runtime
