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

Last Updated : 29 Jun, 2020
The stats.blocks property is an inbuilt application programming interface of the fs.Stats class is used to get the number of blocks allocated for the file. Syntax: 
stats.blocks;
Return Value: It returns a number or BigInt value that represents the number of blocks allocated for the file. Below examples illustrate the use of stats.blocks property in Node.js: Example 1: javascript 
// Node.js program to demonstrate the
// stats.blocks property

// Accessing fs module
const fs = require('fs');

// Calling fs.Stats stats.blocks
// using stat
fs.stat('./', (err, stats) => {
    if (err) throw err;

    // The number of blocks allocated
    // for the file 
    console.log("using stat: " 
                + stats.blocks);
});

// Using lstat
fs.lstat('./', (err, stats) => {
    if (err) throw err;

    // The number of blocks allocated
    // for the file 
    console.log("using lstat: " 
                + stats.blocks);
});
Output: 
using stat: 8
using lstat: 8
Example 2: javascript 
// Node.js program to demonstrate the
// stats.blocks property

// Accessing fs module
const fs = require('fs').promises;

// Calling fs.Stats stats.blocks
(async () => {
    const stats = await fs.stat('./filename.txt');

    // The number of blocks allocated
    // for the file
    console.log("using stat synchronous: "
                + stats.blocks);
})().catch(console.error)
Output: 
using stat synchronous: 8
Note: The above program will compile and run by using the node filename.js command and use the file_path correctly. Reference: https://nodejs.org/api/fs.html#fs_stats_blocks
