Understanding Node.js and its Potential

What is Node.js?

Node.js is an open-source JavaScript runtime environment. It functions on various computing platforms. Chrome’s V8 JavaScript engine is used for building Node.js

How Node.js aids in building applications?

Node.js consists of all the features you need whenever you run a program written in JavaScript. This allows you to use JavaScript to code the command line tools. In addition to that, it also enables server scripting, thereby permitting to create dynamic web page content before you send it to the user’s browser.

What is Node.js used for?

Node.js is used in various applications. The experts say that Node.js has increasing demand coming second to Big Data specialists. The main reason for these increasing demands is multiple uses and advantages of Node.js. Many renowned corporate companies across the globe make use of Node.js.

1) Creating Chat rooms

Whenever it comes to developing some real-time applications like chat rooms, Node.js shines brightly. Although many people these days use phone applications and social media for communication, the chat rooms are still means of correspondence between the users and the brands.

2) Collecting Large Data

The software can be used whenever you gather significant amounts of information. Since the extraction of the database is a blocked function, receiving large amounts of data can result in a hold-up.

3) Audio and Video streaming

All the files that are uploaded to the streaming sites like Veyo and YouTube must be processed before they are heard or viewed by people. This typical process of audio and video uploads saves lots of time and also makes the uploads accessible faster.

How to Build a Simple Engaging blog using Node.js?

The first and foremost step is downloading Node.js on your machines and later install it. After the installation, you need to select the location where you will be saving your project. Then, open a new folder for the blog and create an app.js file in it.

Start Building

Then use Express for setting up your web server fast. Hence, firstly, write, and then run the Express installation code. This particular express code is necessary for saving dependency locally so that you can use it in your application. Next, you need to write the code in app.js.

Provide a New Route for Serving Your Page

Next step is writing code to add a new route to the server page. After hitting the way, the index page must be rendered. Let us backtrack here for creating the index view to make sure to run the relevant code.

Restarting Your Application

You need to restart the application and go to the specific port in order to check your progress thus far. You will then realize that you should store your posts from within the form as it would be posting everything to “add post”. Hence you should create a route for the same and the schema which would store all that information.

Installation of MongoDB

For the database connection, you can use MongoDB. Hence, install MongoDB on your machine and then create a data folder which stores all your database system. Then, give specific folder appropriate permissions by running the relevant code. After running the MongoDB terminal, you are set to go.

Setting up the Schema

For setting up the schema and its model, create a mongoose schema. The next step is to add all the relevant parameter definitions. After doing that, you need to assign a mongoose model to it by providing the necessary codes.

Adding the “add post” Route

Provide an “add post” route that would be storage for all the information. Also, redirect to your particular path after finishing this and add an error whenever required. You need to take hold of the information before sending the same to view in the root route.

Advantages of Node.js

1) Node.js is scalable

The critical benefit of Node.js is the developers find it easier to scale the applications in horizontal and vertical directions. All the forms can be mounted in a parallel manner by adding nodes to the existing system.

2) Easier to Learn

As JavaScript is a popular programming language, many front-end developers have a good grasp of it. It becomes more comfortable to use Node.js at the back-end as learning Node.js consumes less time.

3) Node.js can be used as a single programming language

Node.js offer developers a luxury to write server-side applications in JavaScript. It allows the Node.js developers to write both front-end and back-end web applications in JavaScript via a runtime environment. They do not need to use any other server-side programming language that makes the deployment of the web application much more straightforward as all the web browsers support JavaScript.
