28-Sep-2023In Node.js, the require function serves a crucial purpose—it's used to load and include external modules or files into your JavaScript code. It plays a central role in Node.js's modular architecture and allows you to organize your code into reusable and separate units, making it easier to manage and maintain your projects. Here's a more detailed explanation of the purpose of the require function:
Here's a simple example of how to use the require function to load an external module:
In the first line, we load the built-in fs module, which provides file system-related functionality. In the second line, we load a custom module named myModule located in the same directory as our script.
Overall, the require function in Node.js is a fundamental part of the CommonJS module system, enabling modularity, code organization, and code reuse in your Node.js applications.
