Node.js stats.size Property from fs.Stats Class

  • Last Updated : 26 Jun, 2020

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:






// 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:




// 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.
