How to install and Configure the Node.js Project

In this article, we will learn how to install and configure the node js project. As we know Nodejs is a server-side programming language and it makes javascript more versatile. Nodejs helps in easily producing fast scalable network applications.

Nodejs uses an event-driven architecture that makes it lightweight.

In ubuntu architecture, if you want to install a node in your local machine you need to download the node package using the following commands.

sudo apt-get install curl
curl -sL https://deb.nodesource.com/setup_13.x | sudo -E bash -
sudo apt-get install nodejs

After downloading the node you can check the version of the Nodejs using the command

node -v
Then we have to start creating our first project in our local machine using Nodejs using the following command and steps to create the project.

  1. Goto directory where you want to create a project could be any directory.
  2. Create a new folder using the command mkdir nodeproject
  3. cd nodeproject

  6. Optionally you can type the author name, project description, and version as per your need in the above screen.
  7. Create a new file name it as server.js in the same directory and write the below code
    This file is basically the server file that you have created, without this server file you can not do any code further. So it is mandatory to create this.
    const express = require("express");
    const app = express();
    const port = process.env.PORT || 3303;
    global.app = app;
    //request handlers
    app.get("/", (req, res) => {
    res.send("Welcome to the Node.js Tutorial! - ");
    });
    app.listen(port, () => {
    console.log("Server started on: " + port);
    });
  8. To run the project you need to install basic packages like express
    We can use the command to download
    npm install express in the command line in the same directory.
  9. To run the project we can use the command npm start as per the below screenshot
    nodecode1
  10. At last, go to your browser and type http://localhost:3303/ and you’ll find the screen as per the screenshot below.
