What is a MEAN Stack?
- MongoDB – Database Management
- Express js – Web framework for Node.js
By replacing Angular.Js with React.js, you get a completely new technology stack called the MERN stack. You can learn more differences about MERN V/s MEAN technology stacks here.
Different Components in MEAN Technology Stack
MongoDB is a schemaless NoSQL database system. Using MongoDB, the developer can save the data in binary JSON format, making it easier to pass data between client and server.
Express is a framework for developing web applications in Node.js. It has a lot of powerful tools for creating single-page and multi-page web apps.
Benefits of Each Component in the MEAN Technology Stack
Below are a few reasons why one should start using MongoDB:
- MongoDB is a NoSQL database, which means that instead of storing data in a relational style, it saves them in binary JSON format documents. MongoDB’s flexibility and adaptability to real-world business scenarios and requirements are due to this capability.
- MongoDB produces indexes to speed up search results. In a MongoDB document, indexing may be applied to any field.
- MongoDB enables the idea of sharding, or horizontal scaling, by separating data across several instances. Even if there is a hardware failure, MongoDB can balance the load and/or replicate the data to keep the system functioning.
- An ultra-fast I/O
- Asynchronous and single-threaded.
- It has an MVC (Model–View–Controller) like structure.
- Express has many robust APIs that make routing easy.
- Easy to configure and customize.
- High Performance
- Supports Single Page Applications
- Handles Dependencies using the in-built dependency injection system
- A combination of MVC(Model-View-Controller) and MVVM(Model-View-ViewModel) reduces line coding
- Supports Parallel Development
- Angular js guides developers through the entire journey of building an app, including designing the UI, writing the business logic, testing, etc.
- Extends HTML support by adding tags, attributes, and expressions.
- It allows easy event handling and also supports data binding.
- Built-in support for AJAX, HTTP, and Observables
- Large community support.
- Codes are cleaner and crisp; it is also good at error handling.
- Easy to Scale
- Allows High-Quality streaming
- Wide community support
- Quicker Responses
- Multiple Technology Friendly
- Shallow Low Learning Curve
- Faster Web App Development
How does the MEAN stack work?
Being a web-based application, MEAN stack works as the data channel between the client-side browser and the server-end. Whenever the client performs a task like putting in credentials or adding an entry into a form field or storing a file on the server, the browser uses MEAN stack to communicate with the server. Angular is the frontend framework that accepts the request and forwards it to Node. Node uses Express to parse the request and convert it a format that MongoDB understands. MongoDB identifies the request and pulls/pushes (depending on the request type) the data to a specified location.
When fetching data, MongoDB returns the data to Node via Express. The Node passes the requested data to the user using Angular frontend. Angular displays the requested data on the browser. The overall interaction can be summarized in the following way.
Advantages of MEAN Stack Development
Speed, simplicity, and scalability
Each of MEAN stack’s technologies was created with speed, flexibility, and usability in mind. As a result, developers now have access to a current and effective technological stack that allows them to build quick, simple, and scalable apps.
Single language programming = Developer productivity.
MEAN stack is a technology stack that is free and open-source. It also has lower development expenses due to its emphasis on single-language programming. Instead of employing separate help, MEAN allows developers to contribute throughout the whole development cycle. Furthermore, developers may exchange and reuse code in a large number of ways.
Is MEAN Stack Right for You?
Don’t be spellbound by the benefits of choosing MEAN stack development services. MEAN stack web development doesn’t need to be meant for you. However, here are some of the disadvantages of MEAN stack:
- Not recommended for large-scale applications.
- No specific general JS coding guidelines.
- Once you have developed the first site using MEAN stack technology, it’s really hard to go back to the old approach.
- It offers poor isolation of servers from business logic.
- You could lose records gradually.
The technologies you choose should depend on the dev team’s skillset, the data, the scale, and the use cases. For example, MEAN stacks are not suitable for projects with a big codebase.
When Can the MEAN Stack be Used?
The MEAN stack isn’t ideal for every application type. However, it shines in a variety of use cases. Because of its scalability and capacity to manage concurrent users, it’s an excellent choice for designing cloud-native apps. The AngularJS frontend framework is also well-suited to the creation of single-page applications (SPAs), which provide all information and functionality on a single page. Here are some examples of where to use MEAN:
- Expense tracking and Billing Software
- eCommerce platforms
- Location and mapping software
- News and eMagazine sites
There is no doubt that MEAN Stack is one of the best choices while developing a robust, dynamic web application, and it only continues to get better with every passing day. Most of the leading companies that have mobile and web applications are making extensive use of MEAN Stack to deliver outstanding results to their customers.
