Course by: MindCraft

In this tutorial, we'll guide you through setting up your first Node.js project. We'll start by writing a simple "Hello, World!" code in Node.js and then show you how to initialize your project using the NPM (Node Package Manager) CLI. This foundational lesson is perfect for beginners, helping you establish a strong base for your Node.js development journey.

Writing Your First "Hello, World!" in Node.js

Begin with a classic "Hello, World!" example to get a feel for coding in Node.js. We'll walk you through writing this simple script, explaining each line to help you understand the basics of how Node.js handles requests and responses.

Understanding the Role of NPM

Learn about NPM, the default package manager for Node.js, and its crucial role in managing dependencies and packages in your project. We'll explain why NPM is essential for Node.js development and how it simplifies the process of adding and managing libraries.

Initializing a Node.js Project with NPM CLI

Discover how to set up a new Node.js project using the NPM CLI. We’ll show you how to create a package.json file, which serves as the configuration file for your project, storing metadata about the project and managing dependencies.

Creating and Understanding package.json

Learn how to customize the package.json file to suit your project's needs. We'll break down the key sections of the file, explaining how to add scripts, manage dependencies, and configure your Node.js application for different environments.

Adding Dependencies to Your Project

Explore how to add external libraries and dependencies to your Node.js project using NPM. We'll demonstrate how to install packages and manage them effectively to enhance your project's functionality.

Running and Testing Your Node.js Application

After setting up your project, we'll run and test the "Hello, World!" application to ensure everything is working as expected. Learn how to use the Node.js runtime to execute your scripts and troubleshoot any potential issues.

Best Practices for Node.js Project Setup

Wrap up with some best practices for setting up a Node.js project. We’ll discuss the importance of a clear directory structure, maintaining your package.json, and keeping your dependencies up to date.
