MEAN Stack Application Development: Harnessing the Full Potential of JavaScript

MEAN Stack Components

Front end Angular.js

Angular.js is the "JavaScript MVW Framework'' for Model View and Whatever. Using Angular.js, you can construct interactive, dynamic online experiences considerably quicker than with JavaScript or jQuery.

Angular comes with all the bells, whistles, and features you would expect of a JavaScript front-end framework. This includes form validation, communication, and localization.

Server tier for Node.js, Express.js or Both

Next, Express.js runs on a Node.js Server. Express.js is an opinionated "fast and simple Node.js web framework." Express.js provides powerful models to handle HTTP requests and responses.

Express.js can be connected to your Angular.js application using XML HTTP Requests (XHRs), GETs, or POSTs. These functions use the Node.js driver of MongoDB to update and access data stored in MongoDB.

This can be done either by using callbacks or promises.

MongoDB Database Tier

Your application may store data such as user profiles, uploads, comments, or even events. If you want to use a database as easily as Angular Express and Node, then you need to choose a tool that is easy to manage.

MongoDB can help: JSON files created by your Angular.js application can be sent directly to Express.js, which will process and store the documents (if they are valid) in MongoDB.

MEAN Stack Workflow

Let's now explore the MEAN development workflow.

1. Designing the Database: MongoDB offers a flexible schema to help you design the database. Define documents and collections to effectively organize your data.

2. Creating the server: Express.js & Node.js can be used to create a powerful backend that handles requests, executes logic and communicates with the database.

Express.js is a middleware and routing management tool that simplifies the process, while Node.js offers a scalable environment.

3. Developing User Interfaces: Use the power of Angular for dynamic, responsive interfaces. The component-based architectural design of Angular, data binding, and strong templating engines enable fast UI creation.

4. Integration of Components: Establish APIs to connect the frontend with the backend. Express.js is used to create API endpoints which communicate with the server and handle data retrieval, manipulation and response to frontend requests.

6. Testing and Debugging: Test and debug your application thoroughly to make sure it is secure, functional, and performs well.

Debug issues that may arise in the testing phase using Chrome DevTools or Postman.

7. Deployment: Preparing your application to be deployed on a web server. Host your MEAN stack app on platforms such as Heroku or AWS and make it available to all users.

The MEAN Stack Has Many Advantages

MEAN applications are cross-platform and can be used in many different ways. MEAN may be applied to a wide range of scenarios, including:

• Tools for workflow management
• News aggregator sites
• Calendar and Todo applications
• Forums interactive

The MEAN stack can be used in many other ways. The stack's components can be easily integrated because they are all based on JavaScript or JSON.

Angular and Express, both part of MEAN, are popular JavaScript frameworks that can be used for front-end or back-end development.

Express is a powerful tool for managing HTTP requests, responses, and middleware. It also includes support for JSON endpoints.

Angular allows you to create dynamic HTML pages which communicate with the backend server.

MEAN stack is ideal for Node.js apps, whether you are building a web app, a microservice, or a simple API. The MEAN stack is open-source and offers developers a free, generous opportunity.

The Disadvantages of MEAN Stack

JavaScript was not originally designed for backend server development. The MEAN stack, which includes the backend server, is built on JavaScript.

This could cause large-scale performance and concurrency issues due to JavaScript's nature.

Delays in development can also lead to poor separation of business logic and server logic, resulting in spaghetti code or bad practices.

Even though there are a lot of guides and tutorials available, most still need concrete JS coding rules for this stack.

Hence, what worked well in one application may only work for one.

When Can The MEAN Stack Be Used?

MEAN uses the three-tier stacking pattern. This includes the application (Express.js, Node.js), database (MongoDB), and display (Angular.js).

MEAN is a great tool for building JavaScript applications, especially in Node.js.

MongoDB is a JavaScript/JSON data store that stores data using a JSON-like format. The MongoDB Query Language is also defined in JSON.

Its command-line interface is a JavaScript Interpreter. MongoDB is a JavaScript/JSON-based data store with advanced features such as indexing, querying, and horizontal scaling.

MongoDB Atlas is a cloud-native, native database service created by MongoDB creators. MEAN stack is ideal for Node.js apps, whether you are building a web app, a simple API, or a Microservice.
