Packages vs. Modules: The Building Blocks of npm
- Packages: A package typically consists of a collection of code often comprising JavaScript files along with a package.json file. This particular file serves as the package identification card encompassing details such as its name, version number, dependencies, and scripts for project management. Packages range in scope from utility functions to comprehensive web application frameworks such, as React or Angular.
- Modules: A module is, like a JavaScript file that offers a particular reusable function. Modules make use of the require() function to bring in code from modules and utilize the exports object to showcase their own functionality. They promote organized and easily maintainable code.
Introduction to packages and modules in npm
The Node Package Manager (npm) serves as a tool for the JavaScript programming language functioning both as a command line utility and package manager. It is the choice for managing dependencies and sharing packages within the NodeJS environment. The public npm registry acts as a centralized platform where developers can upload, discover, and incorporate packages (such, as libraries or modules) into their projects.
