Node.js Crash Course - Learn the Fundamentals of Node.js

TLDRIn this Node.js Crash Course, we will explore the basics of Node.js, including its features, modules, and event-driven, non-blocking I/O model. We'll build a web server using only Node.js and discuss the differences between Node.js and Express. This course is perfect for beginners interested in learning server-side JavaScript.

Key insights

📚Node.js is a JavaScript runtime, not a language, framework, or library.

🔥Node.js is fast, efficient, and highly scalable, making it popular in startups and microservices.

🔌Node.js uses an event-driven, non-blocking I/O model, which optimizes throughput and scalability.

📦Node.js has a large set of core modules and a package manager (NPM) for easy installation of third-party packages.

🗄️Node.js is great for building REST APIs, microservices, CRUD apps, real-time services, and tools/utilities.

Q&A

What is the difference between Node.js and Express?

—Node.js is a JavaScript runtime, while Express is a web application framework for Node.js. Node.js allows you to run server-side JavaScript, whereas Express makes it easier to build web applications with Node.js by providing additional features and abstractions.

What types of projects is Node.js good for?

—Node.js is great for building REST APIs, microservices, CRUD apps, real-time services, and tools/utilities. It's especially popular in startups due to its speed, efficiency, and scalability.

What is NPM?

—NPM (Node Package Manager) is a package manager for Node.js. It allows you to easily install, manage, and use third-party packages or modules in your Node.js projects.

Does Node.js work with databases?

—Yes, Node.js can work with any database, but it's commonly used with MongoDB due to its speed and scalability. However, you can use relational databases or any other database with Node.js.

Is Node.js suitable for CPU-intensive tasks?

—No, Node.js is not suitable for CPU-intensive tasks as it runs on a single thread and is optimized for handling I/O operations.
