A warm welcome to the Node.js: Building Scalable and High-Performance Applications course by Uplatz.
Node.js is an open-source, back-end JavaScript runtime environment that runs on the Chrome V8 engine and executes JavaScript code outside a web browser. It is used for building scalable and high-performance network applications.
How Node.js Works
Event-driven, non-blocking I/O model: Node.js uses an event-driven, non-blocking I/O model which makes it lightweight and efficient. This means that when a request is made to the server, it doesn't block other requests from being processed. Instead, it continues to process other requests and once the initial request is complete, it emits an event to notify the server.
Single-threaded: Node.js uses a single thread to handle multiple requests. This is different from traditional web servers which use multiple threads to handle requests. Node.js can handle a large number of requests concurrently due to its non-blocking I/O model.
Modules: Node.js has a rich ecosystem of modules that can be used to perform various tasks. These modules can be easily installed using the npm (Node Package Manager) tool.
Core Features of Node.js
Asynchronous and event-driven: All APIs of Node.js are asynchronous, meaning that the server doesn't wait for an API to return data. It moves to the next API after calling it, and a notification mechanism of Events of Node.js helps the server to get a response from the previous API call.
Fast: Node.js library is very fast in code execution because it is built on Google Chrome's V8 JavaScript Engine.
Single-threaded but highly scalable: Node.js uses a single-threaded model with event looping. Event mechanism helps the server to respond in a non-blocking way and makes the server highly scalable as opposed to traditional servers which create limited threads to handle requests.
No buffering: Node.js applications never buffer any data. These applications simply output the data in chunks.
Benefits of using Node.js
Scalability: Node.js is highly scalable due to its non-blocking I/O model and event-driven architecture.
Performance: Node.js is very fast and efficient due to its use of the V8 JavaScript engine and its non-blocking I/O model.
Easy to learn: Node.js is easy to learn for developers who are already familiar with JavaScript.
Large community: Node.js has a large and active community which provides support and contributes to the development of the platform.
Some of the reasons why you should learn Node.js
High demand: Node.js is in high demand and there are many job opportunities available for Node.js developers.
Full-stack development: Node.js can be used for both front-end and back-end development, which allows developers to build full-stack web applications using a single language.
Microservices: Node.js is well-suited for building microservices, which are small, independent services that can be deployed and scaled independently.
Real-time applications: Node.js is ideal for building real-time applications such as chat applications, online games, and collaboration tools.
