Node.js stats.blksize Property from fs.Stats Class
The stats.blksize property is an inbuilt application programming interface of the fs.Stats class is used to get the block size for I/O operations in the file system in bytes.
Syntax:
stats.blksize;
Return Value: It returns a number or BigInt value which represents the block size for I/O operations in the file system in bytes.
Below examples illustrate the use of stats.blksize in Node.js:
Example 1:
const fs = require( 'fs' );
fs.stat( './' , (err, stats) => {
if (err) throw err;
console.log( "using stat: the block "
+ "size for I/O operations in the"
+ " file system in bytes is "
+ stats.blksize);
});
fs.lstat( './' , (err, stats) => {
if (err) throw err;
console.log( "using lstat: the block "
+ "size for I/O operations in the "
+ "file system in bytes is "
+ stats.blksize);
});
|
Output:
using stat: the block size for I/O operations
in the file in bytes is 4096
using lstat: the block size for I/O operations
in the file in bytes is 4096
Example 2:
const fs = require( 'fs' ).promises;
(async () => {
const stats = await fs.stat( './' );
console.log( "using stat synchronous: "
+ "the block size for I/O operations"
+ " in the file system in bytes is "
+ stats.blksize);
})(). catch (console.error)
|
Output:
(node:6376) ExperimentalWarning: The fs.promises
API is experimental
using stat synchronous: the block size for I/O
operations in the file system in bytes is 4096
Note: The above program will compile and run by using the node filename.js
command and use the file_path correctly.
