It will truncate the file’s length as mentioned. It will return the mentioned file’s stats. It lets you rename the file or directory name. It will resolve the relative path for you. You can read the symbolic link’s content. It will open the file to make the changes. ![]() It will create a new hard link for the specified file. Lets you change the owner and group of the file. It lets you change the permission for the file. MethodĬheck the existence of the file and access it with its permission. const fs = require('fs') Īfter using the above code, you can get access to the several methods that are mentioned below. All you need is to include it in your code using the “require” function and passing fs as the parameter, as shown below. The fs modules let you seamlessly work and manage the files and directories in your system. If you do not want to implement the above scenario, you must use the asynchronous fs method to deal with the file system. Some of those scenarios load configs before the actual program runs.Ĭonst config = JSON.parse(fs.readFileSync("./config.json")) But, in some scenarios where you want to explicitly block your program’s execution, you can go for the synchronous versions. So, you must also go for the asynchronous versions of the fs methods while working with the filesystem. It is recommended that all the file-related and I/O-related operations must be done asynchronously to avoid the vagueness of your code. To avoid the blocking situation and unresponsive application, the I/O operations are also done asynchronously. But, not all the functions are asynchronous, some of the functions are synchronous, such as readFileSync and writeFileSync. The fs module supports the asynchronous and callback-based functions by default. But, before that, we will learn about asynchronous and synchronous fs methods. If you have Node.js, you can start with the coding part. You can even join the knowledgeHut Node.js master class to get more information about working with Node.js in detail. To get started with your Node.js, first install the latest version on your system. When you should not use the Node.js fs module? Prerequisites How to create and delete a system directory in Node.js? How to delete a file (new or existing) using fs.unlink? What is the basic usage of the fs (file system) module? ![]() In this Node.js master class, you will learn the following. There is no need to install fs in node js to use it. ![]() The fs module helps you to work around the files and directories to carry out different tasks, such as a store, access, read, write, rename, and others. One of those useful modules is the nodejs install “fs” module. Node.js has a wide range of modules for various purposes and to ease your development task. For more information, check out MERN Full Stack Developer course. If you are a beginner and want more information, then you can go for full stack developer training. The node js fs install module comes with all basic functions that you can perform for a specific file within your project. Node.js lets the developers alter the files with its built-in fs (file system) module. Not just handling, you can easily read, write, rename, or delete a file and save time for every developer. Working and managing files is crucial, but with Node.js you can do it efficiently. ![]() If any of the files malfunctions, it can impact the entire project. It is evident that any project can not proceed without having different files holding the code.
