MEAN Stack Training in Kalyan Nagar

Career opportunities in Mean Stack:

In this blog, we are going to learn all about MEAN stack and the different technologies used in it. We will start with the introduction to MEAN, and then we will dive deep into it for understanding what MongoDB, Express.js, Angular.js, and Node.js are. Once we learn all about MEAN stack, we will move ahead and answer the questions: ‘Who is a MEAN Stack Developer? and ‘What is the scope of MEAN Stack?'

MEAN is a collection of technologies ( MongoDB, Express.js,  Angular.js and Node.js) associated with JavaScript, which is used to build web-based applications. MEAN stack is responsible for the development of each component of website development from client-side/server-side to database handling, and all these are based on one technology, i.e., JavaScript. MEAN stack is a branch of full-stack development that is used by developers in building fast and powerful web-based applications.

If we want to build a dynamic website, then MEAN stack is an ideal choice for us and the reason is simple: MEAN is user-friendly. On top of it all, the technology of MEAN stack is open-source, i.e., free to use; with the help of MEAN stack, we can make prototypes for our website very quickly and organize our website easily.

Technologies That Come Under MEAN

• MongoDB:It handles the database of web applications.
• js:It is a Node.js framework used to build APIs for web applications.
• js:It is a frontend development framework majorly maintained by Google.
• js:It is used to handle the server-side.

Now that we know about MEAN stack, let’s further see each of its components in detail. We will start with MongoDB, and then we will learn the different versions of it, why it is used in MEAN, and much more.

What is MongoDB?

MongoDB is written in C++ and it is an open-source, multi-platform database. In MongoDB, the storage of data (in key-value pairs) is more flexible than the other databases, and here the type of data stored is binary like JSON.

MongoDB is a document-oriented NoSQL database, i.e., the fields can vary from document to document and the data structure can be changed over time. A document in MongoDB resembles an object in OOPS.

If we are having large tables with a huge amount of data (up to millions), then we can manage them easily with the help of MongoDB. Inserting new fields to MongoDB is very easy because it won’t update the entire table if we insert new data fields, which makes MongoDB an ideal choice for a database system. Moreover, with MongoDB, we can build a whole web application by using just one scripting language, JavaScript, and that’s the biggest advantage of all.

What is Express js?

Express.js, a mature, flexible, and lightweight server framework, is used for the server-side applications. With the help of Express.js, we can build single-page, multi-page, or hybrid web applications. Express is also written in JavaScript. To provide support for templates, it uses the Pug engine (one of the most popular templating engines).

Express is a framework for Node.js. It has drawn heavy inspiration from Sinatra, the popular Ruby framework.

In this blog, now, we will check out some of the core features of Express.js.

Core Features of the Express.js Framework

• As mentioned, Express can be used to design single-page, multi-page, or hybrid web applications.
• It allows developers to set up middlewares to respond to HTTP requests.
  To perform different actions based on the HTTP method and the URL, Express defines a routing table.
• We can dynamically render HTML pages by passing arguments to templates with the help of Express.

Why should we use Express.js?

• Express is an ultra-fast I/O. As a server-side language, we expect it to be fast and it is.
• Express is asynchronous and single-threaded.
• It has an MVC (Model–View–Controller) like structure.
• Express has many robust APIs that make routing easy.

In the process of learning Express.js, so far, we have seen ‘What is Express js? its core features, and why we should use it. Moving ahead, we will have a look at how the code looks like in Express.

What is Angular.js?

Angular.js is a JavaScript framework created by Miško Hevery. It is an open-source framework maintained by Google. It is mainly used to introduce the  MVC architecture in the browser-based applications that make the development and testing processes easier. Angular helps us in creating a smarter web app that supports personalization.

Angular is a UI framework for dynamic web applications that allow its users to use HTML as a template language. It helps users extend HTML’s syntax to express the components of their application. We won’t be required to write plenty of code in Angular which is an important feature provided by it.

Angular provides all those features that we expect from HTML. It is specifically designed for the UI development of web applications. For static documents, HTML is a great declarative language, but it does not have that much content which is required for creating web applications.

After the release of Angular js, the problem of impedance mismatch between dynamic applications and static documents got resolved with the help of its features. Let’s further see the features of Angular.js.

Features of Angular.js

• Library: In Angular js, libraries are a collection of functions which are useful while writing web apps. JQuery is a JavaScript-based library which is widely used by Angular.js.
• Framework:Frameworks are a particular implementation of a web application, where your code fills in the details. So, the frameworks are responsible for calling the code, when it needs something app-specific. In Angular, Durandal, ember, etc. some of the frameworks used.
