Last Updated :

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:
const fs = require( 'fs' );
fs.stat( './' , (err, stats) => {
if (err) throw err;
console.log( "using stat: "
+ stats.blocks);
});
fs.lstat( './' , (err, stats) => {
if (err) throw err;
console.log( "using lstat: "
+ stats.blocks);
});
|
Output:
using stat: 8
using lstat: 8
Example 2:
const fs = require( 'fs' ).promises;
(async () => {
const stats = await fs.stat( './filename.txt' );
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.
