Node.js stats.mtimeMs Property from fs.Stats Class
The stats.mtimeMs 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 since the POSIX epoch expressed in milliseconds.
Syntax:
stats.mtimeMs;
Parameters: This property does not accept any parameters.
Return Value: It returns a number or BigInt value that represents the timestamp when the file is modified last time since the POSIX epoch expressed in milliseconds.
Below examples illustrate the use of stats.mtimeMs property in Node.js:
Example 1:
const fs = require( 'fs' );
fs.stat( './' , (err, stats) => {
if (err) throw err;
console.log( "Using stat: " + stats.mtimeMs);
});
fs.lstat( './filename.txt' , (err, stats) => {
if (err) throw err;
console.log( "Using lstat: "
+ stats.mtimeMs);
});
|
Output:
Using stat: 1592665056784.809
Using lstat: 1592665183682.0176
Example 2:
const fs = require( 'fs' ).promises;
(async () => {
const stats = await fs.stat( './filename.txt' );
console.log( "using stat synchronous: "
+ stats.mtimeMs);
})(). catch (console.error)
|
Output:
Using stat synchronous: 1592665183682.0176
Note: The above program will compile and run by using the node filename.js
command and use the file_path correctly.
