What is a MEAN stack?

• The MEAN stack is the JavaScript-based framework for developing a web applications.
• MEAN is named after a MongoDB, Express, Angular, and Node,a four key technologies that make up layers of the stack.
• MongoDB — document database.
• Express(.js) — Node.js web framework.
• Angular(.js) — a client-side JavaScript framework.
• Node(.js) — a premier JavaScript web server.
• There are variations to a MEAN stack such as MERN (replacing Angular.js with React.js) and a MEVN (using Vue.js).
• The MEAN stack is one of the most popular technology concepts for the building web applications.

How does MEAN stack work?

MEAN stack architecture: The MEAN architecture is designed to make a building web applications in JavaScript and handling a JSON incredibly easy.

MEAN stack components:

• Angular.js front end.
• Express.js and Node.js server tier.
• MongoDB database tier.

Advantages of the MEAN stack:

MEAN applications can be used in more ways with a cross-platform write-once approach.While a MEAN is particularly suited to real-time applications, particularly those running natively in a cloud and single-page (dynamic) web applications built in a Angular.js:

It can be used for other use cases are:

• Workflow management tools.
• News aggregation sites.
• Todo and calendar applications.
• Interactive forums.

Disadvantages of the MEAN stack:

• JavaScript is the great modern language, but it wasn’t initially designed to build a back-end servers.
• Since foundation of the MEAN stack is JavaScript, including a back-end server.
• It might come with the concurrency and performance problems at scale due to the JavaScript nature.
• Additionally, since a development opportunity is so rapid, business and server logic might suffer from a poor isolation.
• Making potential spaghetti code and bad practices a reality along way.
• Finally, although there are more guides and tutorials out there, they generally will not include a concrete JS coding guidelines appropriate for this stack.
• Therefore, something that worked really well for the one application might surface issues for another.

When can MEAN stack be used?

• Three -tier stack pattern, including a display tier (Angular.js), application tier (Express.js and Node.js), and a database tier (MongoDB).
• If building a JavaScript application, particularly in the Node.js, then should give a MEAN serious look.
• MongoDB stores data in the JSON-like format (BSON, a binary JSON extension), a MongoDB Query Language (MQL) is explained in JSON, and its command line interface (CLI) is JavaScript interpreter.
• Using MEAN stack with a MongoDB Atlas.
• The MongoDB Node.js driver makes working with the MongoDB from inside a Node.js script simple and an intuitive for developers — saving developers time and also increasing their productivity.
• Next, need a MongoDB database. The simplest way to get started with MongoDB is to create free cluster in a MongoDB Atlas.
• MongoDB’s fully managed, multi-cloud document database as service.

How secure is a MEAN stack?

Recommend using a MEAN stack with MongoDB Atlas, since Atlas has been built-in credentials, a firewall, and end-to-end encryption, which is best foundation for securing a MongoDB.

Conclusion:

There are more technologies that full-stack developers work with, but over a course of time, IT specialists have come to most optimal set of tools that allows delivering a best possible results.This set is called a MEAN stack, which consists of a MongoDB, Express.js, Angular, and Node.js.
