So, to import and use the fs module methods, you would do this: const `) In the CJS style, we use the require method to import a method from a module. Please open your favorite source code editor and try them out as you read along.įirst, import the fs module to your source file to start working with the file system methods. Now we will learn about each of these operations with example source code. Working with files involves various operations with files and directories (folders). All the examples we will see in this article are in the CJS style. With Node.js version 14 and onwards, you can create and use Node.js modules in two ways: CommonJS (CJS) and ESM (MJS) modules. Node.js offers plenty of modules to abstract many low-level functionalities for you. Likewise, an http module utilizes its functions to create a server and many more operations. For example, you’ve got the fs module to interact with the file system. Node.js modules are a set of functionalities available as APIs for a consumer program to use. You can also use them to perform both synchronous and asynchronous file operations.īefore we take a deep dive into the file system module, let’s have a sneak peek at what the Node.js module is all about. Most of the APIs are customizable with options and flags. It provides several APIs to interact with the file systems seamlessly. The Node.js file system module has got all these covered. At the same time, your application may need to read configuration files, move files, or even change their permissions programmatically. Your users may want to upload images, resumes, or other files to a server. Working with files and directories is one of the basic needs of a full-stack application. A high-level understanding of JavaScript functions, callback functions, and promises will help you get a grip on this subject even faster. It would help if you also have a basic knowledge of JavaScript to work on Node.js modules like file systems (also known as “FS” or “fs”). Node.js doesn’t require any complex hardware to run, making it easy to download and install Node.js on your computer. The primary prerequisite is Node.js installation on your operating system.
