Node.js stats.mtime Property
The stats.mtime property is an inbuilt application programming interface of the fs.Stats class is used to get the timestamp when the file is modified last time.
Syntax:
stats.mtime;
Parameters: Properties does not have any parameter.
Return Value: It returns a Date which represents the timestamp when the file is modified last time.
Below examples illustrate the use of stats.mtime property in Node.js:
Example 1:
// Node.js program to demonstrate the // stats.mtime Property // Accessing fs module const fs = require('fs'); // Calling fs.Stats stats.mtime // using stat fs.stat('./', (err, stats) => { if (err) throw err; // The timestamp when the file // is last modified console.log("Using stat: " + stats.mtime); }); //using lstat fs.lstat('./filename.txt', (err, stats) => { if (err) throw err; // The timestamp when the file // is last modified console.log("Using lstat: " + stats.mtime); }); |
Output:
Using stat: Sun Jun 21 2020 01:08:08 GMT+0530 (India Standard Time) Using lstat: Sun Jun 21 2020 01:10:16 GMT+0530 (India Standard Time)
Example 2:
// Node.js program to demonstrate the // stats.mtime Property // Accessing fs module const fs = require('fs').promises; // Calling fs.Stats stats.mtime (async () => { const stats = await fs.stat('./filename.txt'); // The timestamp when the file // is last modified console.log("Using stat synchronous: " + stats.mtime); })().catch(console.error) |
Output:
Using stat synchronous: Sun Jun 21 2020 01:10:16 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.
