Node.js stats.atimeMs Property from fs.Stats Class

  • Last Updated : 29 Jun, 2020

The stats.atimeMs property is an inbuilt application programming interface of the fs.Stats class is used to get the timestamp when the file is accessed last time since the POSIX epoch expressed in milliseconds.

Syntax:

stats.atimeMs;

Parameters: This property does not use any parameters.

Return Value: It returns a number or BigInt value that represents the timestamp when the file is accessed last time since the POSIX epoch expressed in milliseconds.

Below examples illustrate the use of stats.atimeMs property in Node.js:



Example 1:




// Node.js program to demonstrate the   
// stats.atimeMs Property
  
// Accessing fs module
const fs = require('fs');
  
// Calling fs.Stats stats.atimeMs
// using stat
fs.stat('./', (err, stats) => {
    if (err) throw err;
  
    // The timestamp when the file
    // is last accessed (in MS) 
    console.log("Using stat: "
            + stats.atimeMs);
});
  
// Using lstat
fs.lstat('./filename.txt', (err, stats) => {
    if (err) throw err;
  
    // The timestamp when the file 
    // is last accessed (in MS) 
    console.log("Using lstat: "
            + stats.atimeMs);
});

Output:

Using stat: 1592664011243.8335
Using lstat: 1592664189785.7615

Example 2:




// Node.js program to demonstrate the   
// stats.atimeMs Property
  
// Accessing fs module
const fs = require('fs').promises;
   
// Calling fs.Stats stats.atimeMs
(async() => {
   const stats = await fs.stat('./filename.txt');
   
   // The timestamp when the file 
   // is last accessed (in MS) 
   console.log("Using stat synchronous: "
            + stats.atimeMs);
})().catch(console.error)

Output:

Using stat synchronous: 1592664546730.291

Note: The above program will compile and run by using the node filename.js command and use the file_path correctly.
