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:
// 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:
// 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.
