If you've been a fan of the Rocket website, you've probably heard the name Node.js. If you've not been a rocket audience, I have to say that NodeJas is at such a level of popularity today that almost everyone involved in programming has heard of it. Today in this training course from Rocket website, we are going to teach you this useful tool for developing back-end applications using JavaScript. But first let's get a little familiar with this tool.

What is Node.js?

Node.js is known as a platform based on the Chrome v8 engine, and allows JavaScript programmers to run (JavaScript) in a variety of situations.

For example, before Node, you could only use JavaScript on the user's browser. You had to go to other programming languages ​​to create server-side applications. But with the introduction of Node.js, you can use JavaScript as a server-side language.

Using backend JavaScript with node is very important, because by learning a language called JavaScript you can become a full-stack developer and create your own frontend and backend websites.

In the Node.js training course, we tried to teach you node in a deep and practical way so that you can easily use JavaScript as a server-side language in the node platform.

What is a platform?

The easiest way to understand the word platform is to give an example. For example, Windows and Linux are known as a platform on which you can run various software.

Node has exactly the same situation, which means that it has prepared a platform that we can use to use our JavaScript code wherever we install Node.js.

For example, if you install Node.js on robotic systems, you can use JavaScript on robotic devices to control them.

What do we need to know to learn Node.js?

The most important thing to learn Node.js is to have enough knowledge and understanding of JavaScript, if you do not know JavaScript well, you should know that it is not yet time to start learning Node.js.

To learn JavaScript, you can see the related courses step by step in the JavaScript Learning Steps section, so that you can learn JavaScript in a good and complete way.

Install, set up and configure Node.js

Fortunately, Node.js is very easy to install and set up. All you have to do is log in to Nodejs.org and download the Nodejs setup file. With a few simple clicks next you will see that Node.js is quickly installed on your operating system and you can use it to develop your application.

Node.js modules

We have three types of modules in Node.js:

• Node kernel modules
• Local Modules
• Third-Party Module

Node kernel modules

These modules are located in the core of the node itself, and you can use these modules only by requiring them in your JavaScript file.

These modules help you easily work with HTTP, files, encryption, streaming, and more. This can be considered as an important advantage of node.

Local modules

In the node context, you can define your code in the form of different modules and use it in different parts of your code.

This can streamline your project code and make it easier to read and debug your code.

Third party modules

In addition to the two types of modules above, we can easily use modules that other people can develop in our project. In this case, we no longer need to do everything ourselves and only by installing one module we can do part of the project. Develop quickly.

In the Node.js course we will introduce you to all three types of these modules and you will practically learn how to use different modules.

NPM (node package management)

One of the most important features of a node that makes it attractive is having a package management system called NPM. With this system you can easily access a large number of packages developed by JavaScript developers.

You do not even need to install NPM because NPM comes with node installed automatically and you can install and launch the package you want in your project with one command.

In the Node.js training course, we will fully teach you how to work with this package manager.

Why should you learn Node.js from Rocket Collection?

In this course, we have tried to teach you Node.js in a deep and practical way and in the form of various examples, and we believe that by watching this course, you can learn Node.js accurately and easily from JavaScript in the backend or anywhere. Use a node that can be installed.

So by learning the Node.js Rocket tutorial, you can quickly and accurately learn Node.js properly.

Who is this special course for?

This course is for people who want to run JavaScript in places other than the user's browser. On the server side, or in the field of artificial intelligence, or in the field of robotics, practically wherever you have the ability to install Node.js.

So if you have such a decision, you can easily reach your goal by watching this course.

What do you earn after completing the course?

• Support and answer your questions
• Earn points and credits to participate in other courses
• Receive course updates for life (if you purchase this course in cash)
• Ability to make money and get real projects
• Familiarity with node and the ability to understand the function of Node.js
• Use Node.js to develop in different spaces

Node.js training course topics

Basic Node Concepts

In this section, we will teach you the basic but important concepts of Node, such as how to execute JavaScript code in Node.js, how to receive a request or send a response, or how to work with files.

NPM Package Manager

As we talked about above, an important feature of node package management. In this part of the course, we will introduce you to the NPM terminal relationship and the commands in this interface in full and in detail.

Debugging the project

In this section you will learn how to debug node project files using an editor or browser to identify and resolve potential problems with your project.

Build a simple web server

We can create a web server using the node platform and its core modules. Web server means that you can send requests to your website domain through the browser and respond to those requests using the web server that you created with node.

Familiarity with expressjs

express.js is known as a framework for the node platform, it can be said that express.js is one of the most popular frameworks for the node. You can use this framework to create and manage your site well, in this part of the Node.js training course we will try to teach you how to work with this framework.
