What do you need to learn nodejs

With the continuous development of Internet technology, Web development has become one of the most popular technical fields in today's society. As a server-side application written in JavaScript language, Node.js is becoming more and more popular among developers because of its advantages such as high efficiency, cross-platform, and easy learning. So, if you also want to learn Node.js, what knowledge points do you need to master?

1. JavaScript Basics

As a server-side application written in JavaScript language, learning Node.js first requires mastering the basic knowledge of JavaScript. JavaScript is an object-oriented, event-driven, dynamically typed programming language. Learning the basic knowledge of JavaScript syntax, data types, conditional statements, loop statements, functions, etc. is a prerequisite for mastering Node.js.

2. Operating System Basics

Node.js has very good operating system compatibility and can run on multiple platforms such as Windows, Linux, and MacOS. However, learning Node.js also requires a certain grasp of the basic knowledge of the operating system. For example, basic operating commands, file operations, permission management, etc. of Linux servers need to be learned.

3. Network Communication Protocol

Node.js applications mainly handle network requests. Therefore, you must have a certain understanding of network communication protocols such as HTTP and TCP/IP. . Understanding network protocols can help us better understand the principle of Node.js processing network requests, and also help us configure and optimize it as needed.

4. Asynchronous Programming

Because the application scenario of Node.js is the network server, and network requests take a very long time, in order to save time and resources, Node.js Adopt an asynchronous programming model. Therefore, learning Node.js also requires mastering the related technologies of asynchronous programming. For example, asynchronous programming technologies such as Promise and async/await.

5. Node.js core module

Node.js has built-in some commonly used core modules, such as http, fs, path, events, etc. Learning Node.js requires mastering the use of these core modules. For example, the http module is used to create an HTTP server, the fs module is used to operate the file system, and the path module is used to manage file paths.

6. NPM and package management

With the continuous expansion of Node.js application scenarios, there are a large number of third-party libraries and frameworks. How to manage these libraries and frameworks becomes a problem. asked a question. The Node.js package management tool NPM was born to solve this problem. Learning Node.js also requires mastering the relevant knowledge of NPM and package management.

7. Express Framework

Express is one of the most commonly used Web frameworks for Node.js. It provides complete routing and middleware, allowing developers to quickly build Web app. Learning Node.js also requires mastering how to use the Express framework.

In short, learning Node.js requires not only mastering basic knowledge, but also learning related frameworks, tools and technologies in order to truly master the development of Node.js. Currently, Node.js has a wide range of application scenarios. Mastering Node.js can not only improve your technical level, but also create a new career path.
