MongoDB – document database
Express(.js) – Node.js web framework system
How does the MEAN stack work?
Angular.js Front End
Express.js and Node.js Server Tier
The following level down is Express.js, running on a Node.js server. Express.js considers itself a “quick, unopinionated, moderate web framework system for Node.js,” and that is in fact precisely what it is.
Express.js has incredible models for URL routing (coordinating with an approaching URL with a server capacity) and taking care of HTTP requests and responses. By making XML HTTP Requests (XHRs) or GETs or POSTs from your Angular.js front-end, you can interface with Express.js capacities that power your application.
Those capacities thus use MongoDB’s Node.js drivers, either by means of callbacks for using Promises, to access and refresh data in your MongoDB database.
MongoDB Database Tier
On the off chance that your application stores any data (user profiles, content, comments, uploads, events, etc.), at that point you will need a data set that is similarly as simple to work with as Angular, Express, and Node.
That is the place where MongoDB comes in: JSON archives made in your Angular.js front end can be shipped off the Express.js server, where they can be handled and (accepting that they’re substantial) put away directly in MongoDB for later retrieval.
Once more, in case you’re working in the cloud, you’ll need to take a gander at MongoDB Atlas. In case you’re hoping to set up your own MEAN stack, read on!
Is MEAN (MongoDB Express.js, Angular.js, Node.js) a full-stack arrangement?
Indeed, MEAN follows the conventional 3-level stack design, including the showcase level (Angular.js), application tier (Express.js and Node.js), and database level (MongoDB).
Why pick the MEAN (MongoDB Express.js, Angular.js, Node.js) stack?
Regardless of whether you’re constructing a high-throughput API, a simple web application, or a microservice, MEAN is the ideal stack for building Node.js applications.
MEAN (MongoDB Express.js, Angular.js, Node.js) Stack Use Cases
While MEAN is especially fit for real-time applications, especially those running locally in the cloud, and single-page (dynamic) web applications worked in Angular.js, it tends to be used in numerous ways.
1. Workflow management tools
2. News aggregation sites
3. Todo and Calendar application sites
4. Intelligent forums
