While MEAN is particularly suited to real-time applications, particularly those running natively in the cloud and single-page (dynamic) web applications built in Angular.js, it can be used for other use cases such as: MEAN applications can be used in many ways with a cross-platform write-once approach.

This will allow you built-in full database security and cross-cloud scalability with the click of a button. That’s where MongoDB comes in: JSON documents created in your Angular.js front end can be sent to the Express.js server, where they can be processed and (assuming they’re valid) stored directly in MongoDB for later retrieval.Īgain, if you want to easily get the best of MongoDB, you’ll want to look at MongoDB Atlas. If your application stores any data (user profiles, content, comments, uploads, events, etc.), then you’re going to want a database that’s just as easy to work with as Angular, Express, and Node.

Those functions, in turn, use MongoDB’s Node.js drivers, either via callbacks or using promises, to access and update data in your MongoDB database. By making XML HTTP requests (XHRs), GETs, or POSTs from your Angular.js front end, you can connect to Express.js functions that power your application. Express.js calls itself a “fast, unopinionated, minimalist web framework for Node.js,” and that is indeed exactly what it is.Įxpress.js has powerful models for URL routing (matching an incoming URL with a server function), and handling HTTP requests and responses. The next level down is Express.js, running on a Node.js server.

The MEAN architecture is designed to make building web applications in JavaScript and handling JSON incredibly easy. How does the MEAN stack work? MEAN stack architecture
