Node.js stats.size Property from fs.Stats Class Last Updated : 26 Jun, 2020 Comments Improve Suggest changes Like Article Like Report The stats.size property is an inbuilt application programming interface of the fs.Stats class is used to get the size of the file in bytes. Syntax: stats.size; Return Value: It returns a number or BigInt value that represents the size of the file in bytes. Below examples illustrate the use of stats.size property in Node.js: Example 1: javascript // Node.js program to demonstrate the // stats.size property // Accessing fs module const fs = require('fs'); // Calling fs.Stats stats.size // for files using stat fs.stat('./filename.txt', (err, stats) => { if (err) throw err; console.log("using stat: the size the " + "file in bytes is " + stats.size); }); // Using lstat fs.lstat('./filename.txt', (err, stats) => { if (err) throw err; console.log("using lstat: the size the" + " file in bytes is " + stats.size); }); Output: using stat: the size the file in bytes is 1112 using lstat: the size the file in bytes is 1112 Example 2: javascript // Node.js program to demonstrate the // stats.size property // Accessing fs module const fs = require('fs').promises; // Calling fs.Stats stats.size (async () => { const stats = await fs.stat('./filename.txt'); console.log("using stat synchronous: the size " + "the file in bytes is " + stats.size); })().catch(console.error) Output: (node:7040) ExperimentalWarning: The fs.promises API is experimental using stat synchronous: the size the file in bytes is 1112 Note: The above program will compile and run by using the node filename.js command and use the file_path correctly.

This method is part of Node.js's File System (fs) module, which provides an API for interacting with the file system.Syntaxfs.readFi 3 min read Node.js fs.exists() Method The fs exists method in node is used to check if the input file or the directory exists or not. It is an inbuilt application programming interface of fs module which provides an API for interacting with the file system in a manner closely modeled around POSIX functions. Syntax:fs.exists( path, callb 2 min read Node fs.existsSync() Method In Node.js, the fs.existsSync() method checks if a file or folder exists at a given path. It's synchronous, meaning it pauses the program until it finds the result (either true if it exists, or false if it doesn't). Because it stops everything while it works, it’s best used for quick checks in small 3 min read Node fs.mkdir() Method The fs.mkdir() method in Node.js is used to create a directory asynchronously.Syntaxfs.mkdir(path, mode, callback)Parameters: This method accepts three parameters as mentioned above and described below: path: This parameter holds the path of the directory that has to be created.mode: This parameter 2 min read Node.js fs.truncate() Method 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 i 2 min read Node.js fs.renameSync() Method In Node.js, the fs.renameSync() method is part of the built-in File System (fs) module and is used to rename or move files and directories synchronously. This method is useful when you need to quickly change a file's name or move it to a different directory synchronously. It blocks the execution of 3 min read Node.js fs.rmdir() Method The fs.rmdir() method is used to delete a directory at the given path. It can also be used recursively to remove nested directories.Syntax: fs.rmdir( path, options, callback )Parameters: This method accepts three parameters as mentioned above and described below: path: It holds the path of the direc 3 min read Node.js fs.stat() Method The fs.stat() method is used to return information about the given file or directory. It returns an fs.Stat object which has several properties and methods to get details about the file or directory. Syntax:fs.stat( path, options, callback )Parameters: This method accept three parameters as mentione 3 min read Node.js fs.mkdtempSync() Method The fs.mkdtempSync() method is an inbuilt application programming interface of fs module which provides an API for interacting with the file system in a manner closely modeled around standard POSIX functions. The fs.mkdtempSync() method creates a unique temporary directory. This is the synchronous v 2 min read Node.js fs.realpath() Method The fs.realPath() method is used to compute the canonical pathname of the given path. It does so by resolving the ., .. and the symbolic links in the path.
