How many modules does nodejs have?

Node.js is a popular JavaScript runtime environment that has broad application capabilities and supports network services, command line tools, real-time communications, web applications, etc. These capabilities are achieved through the use of modules.

So, the node.js module is the core of node.js, and it is the building block of all node.js programs. Currently, the number of node.js modules has exceeded 200,000 and is still growing.

Each module contains one or more functions, classes, objects, or variables that are used to perform specific tasks. These modules are divided into two types: built-in modules and third-party modules.

Built-in modules are modules that Node.js has pre-installed and are part of the core functionality. For example, fs, http, net, os, path and other modules are built-in modules.

Third-party modules are created by other developers and can be installed and updated using npm (Node Package Manager). These modules are widely used in web applications, database management, integration, automation, etc. For example, MongoDB, Express, Socket.io, Lodash, etc. are all third-party modules.

Node.js provides the require function to import modules. In a Node.js application, if you need to use a specific module, just use the require function to import it into the current context.

For example, to use the built-in http module of Node.js, you can write like this:

const http = require('http');

If you want to use a third-party module, such as Lodash, you can write like this:

const _ = require('lodash');

In Node.js development, the importance of modules is self-evident. Using modules makes your code more modular, extensible, and maintainable. Therefore, it is very important to master Node.js module development skills.

In short, the current number of Node.js modules has exceeded 200,000, including some standard built-in modules and widely used third-party modules. Node.js modules provide various benefits such as organizing code, reusing code, improving code maintainability, etc., which can help developers complete tasks faster and develop better applications.
