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:
javascript
Output:
javascript
Output:
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);
});
using stat: 8 using lstat: 8Example 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)
using stat synchronous: 8Note: The above program will compile and run by using the
node filename.js command and use the file_path correctly.
