The fs.rmdirSync() method is used to synchronously delete a directory at the given path. It can also be used recursively to remove nested directories by configuring the options object. It returns undefined.Syntax:...

The fs.chmod() method is used to change the permissions of a given path. These permissions can be specified using string constants or octal numbers that correspond to their respective file modes....

Asynchronous fs methods in Node.js do not block the event loop and handle multiple operations concurrently, improving performance while Synchronous fs methods block the event loop until the operation completes, which can lead to inefficiencies and slower performance for I/O-bound tasks....

The fs.lstatSync() method is used to synchronously return information about the symbolic link that is being used to refer to a file or directory. The fs.Stat object returns several fields and methods to get more details about the file....

The fs.truncate() method in node.js is used to change the size of the file i.e either increase or decrease the file size. This method changes the length of the file at the path by len bytes. If len represents a length shorter than the file’s current length, the file is truncated to that length. If it is greater than the file length is padded by appending null bytes (x00) until len is reached....

Node.js File System module is used to handle file operations like creating, reading, deleting, etc. Node.js provides an inbuilt module called FS (File System). Node.js gives the functionality of file I/O by providing wrappers around the standard POSIX functions. All file system operations can have synchronous and asynchronous forms depending on user requirements...

The fs.watchFile() method is used to continuously watch for changes on the given file. It has a callback listener that is called every time the file is accessed. It has an optional options parameter that can be used to specify properties like the interval on how often the file has to be polled and whether the process would continue as long as the file is being watched....

The fs.accessSync() method is used to synchronously test the permissions of a given file or directory. The permissions to be checked can be specified as a parameter using file access constants. It is also possible to check multiple file permissions by using the bitwise OR operator to create a mask with more than one file constant....

In this article, we looked at how to access the file system in NodeJS and how to perform some useful operations on files....

In this article, we are going to see how can you run a batch file with input and get an output file in Node.js. A batch file is a script file that stores command to be executed in a serial order....

The fsPromises.stat() method is used to return information about the given file or directory. The Promise is resolved with the fs.Stats object for the given path....

The fs.writeFile() is a method defined in the File System module of Node.js. The File System module is basically to interact with the hard disk of the user’s computer. The fs.writeFile() method asynchronously writes data to a file, replacing the file if it already exists....
