The fs.writeFileSync() method is a synchronous method. It creates a new file if the specified file does not exist. Also, the ‘readline-sync’ module is used to enable user input at runtime....

In Node.js, the fs (File System) module furnishes a collection of methods for interacting with the file system. Among these methods, fs.readFile() stands out as a fundamental tool for reading data from files asynchronously. This article will delve into the fs.readFile() method, exploring its syntax, parameters, usage, and error handling....

fs.writeFile() method is used to asynchronously write the specified data to a file. By default, the file would be replaced if it exists. The ‘options’ parameter can be used to modify the functionality of the method....

The fs.readdirSync() method is used to synchronously read the contents of a given directory. The method returns an array with all the file names or objects in the directory. The options argument can be used to change the format in which the files are returned from the method....

The fs.readdir() method is used to asynchronously read the contents of a given directory. The callback of this method returns an array of all the file names in the directory. The options argument can be used to change the format in which the files are returned from the method....

The createReadStream() method is an inbuilt application programming interface of fs module which allow you to open up a file/stream and read the data present in it.Syntax:...

The createWriteStream() method is an inbuilt application programming interface of fs module which allows to quickly make a writable stream for the purpose of writing data to a file. This method may be a smarter option compared to methods like fs.writeFile when it comes to very large amounts of data....

The fs.copyFile() method is used to asynchronously copy a file from the source path to the destination path. By default, Node.js will overwrite the file if it already exists at the given destination. The optional mode parameter can be used to modify the behavior of the copy operation....

The fs.mkdir() method in Node.js is used to create a directory asynchronously....

The fs.appendFile() method is used to asynchronously append the given data to a file. A new file is created if it does not exist. The options parameter can be used to modify the behavior of the operation....

The fs.existsSync() method is used to synchronously check if a file already exists in the given path or not. It returns a boolean value which indicates the presence of a file....

To create the file, to write to a file, or to read a file fs.open() method is used. fs.readFile() is only for reading the file and similarly fs.writeFile() is only for writing to a file, whereas fs.open() method does several operations on a file. First, we need to load the fs class which is a module to access the physical file system. For it require method is used. For example: var fs = require(‘fs’);...
