About This Course

What is Node Js?

Node.js is an open-source, server-side runtime environment that allows developers to run JavaScript code on the server. It is built on the Chrome V8 JavaScript engine, which is known for its speed and performance. Node.js is designed for building scalable network applications and is particularly well-suited for creating web servers and APIs

What is Need of Node Js?

Node.js addresses several needs and offers various advantages in the realm of server-side and back-end development.

Non-Blocking, Asynchronous I/O: Node.js is designed to handle I/O-bound operations efficiently, such as reading and writing files, making network requests

Full-Stack JavaScript Development: Node.js allows developers to use JavaScript both on the front end (in web browsers) and the back end (on the server).

Performance: Node.js is built on the Chrome V8 JavaScript engine, known for its speed and performance.

Community and Ecosystem: Node.js benefits from a large and active community. It has a vast ecosystem of open-source packages and libraries available through npm (Node Package Manager).

Microservices and APIs: Node.js is often used to create RESTful APIs and microservices. Its lightweight and efficient nature makes it a good fit for building the back-end services of a microservices architecture.

Real-Time and WebSocket Applications: Node.js is ideal for developing real-time applications that require bi-directional communication, such as chat applications, collaborative tools, and online gaming platforms.

Learning Objectives

JavaScript Fundamentals: While Node.js focuses on server-side development, you'll still need a strong foundation in JavaScript, including concepts like variables, data types, functions, and control flow.
Asynchronous JavaScript: You'll learn how to work with asynchronous JavaScript, understanding callbacks, promises, and async/await, which are crucial for handling non-blocking I/O operations.
Node.js Basics: You'll gain an understanding of the Node.js runtime environment, how to install it, and how to run JavaScript code on the server. You'll also explore the Node.js event loop, which is central to its non-blocking nature.
Core Modules: Node.js provides a set of built-in modules for tasks like file system operations, network communication, and data manipulation.
npm (Node Package Manager): You'll get familiar with npm, the package manager for Node.js, which allows you to install, manage, and publish third-party packages and libraries.
Working with Databases: You'll learn how to interact with databases in Node.js. This can include using database libraries like MongoDB / MySQL, or connecting to databases through Object-Relational Mapping (ORM) tools like.
Error Handling and Debugging: You'll gain knowledge on how to handle errors gracefully and debug Node.js applications effectively.
