The stats.birthtime property is an inbuilt application programming interface of the fs.Stats class is used to get the timestamp when the file is created.
Syntax:
stats.birthtime
Return Value: It returns a Date that represents the timestamp when the file has been created.
Below examples illustrate the use of stats.birthtime property in Node.js:
Example 1:
// Node.js program to demonstrate the // stats.birthtime property // Accessing fs module const fs = require( 'fs' );
// Calling stats.birthtime property // from fs.Stats class using stat fs.stat( './' , (err, stats) => {
if (err) throw err;
// The timestamp when the file is created
console.log( "Using stat: " + stats.birthtime);
}); // Using lstat fs.lstat( './filename.txt' , (err, stats) => {
if (err) throw err;
// The timestamp when the file is created
console.log( "Using lstat: " + stats.birthtime);
}); |
Output:
Using stat: Wed May 13 2020 18:38:31 GMT+0530 (India Standard Time) Using lstat: Sun Jun 21 2020 01:22:55 GMT+0530 (India Standard Time)
Example 2:
// Node.js program to demonstrate the // stats.birthtime property // Accessing fs module const fs = require( 'fs' ).promises;
// Calling fs.Stats stats.birthtime (async () => { const stats = await fs.stat( './example_file.txt' );
// The timestamp when the file is created
console.log( "Using stat synchronous: "
+ stats.birthtime);
})(). catch (console.error)
|
Output:
Using stat synchronous: Sun Jun 21 2020 01:22:55 GMT+0530 (India Standard Time)
Note: The above program will compile and run by using the node filename.js
command and use the file_path correctly.
