Sometimes, we want to get a file’s last modified date in Node.js

In this article, we’ll look at how to get a file’s last modified date in Node.js.

How to get a file’s last modified date in Node.js?

To get a file’s last modified date in Node.js, we can use the fs.stat or fs.statSync method.

For instance, we write

fs.stat("/dir/file.txt", (err, stats) => {
  const {
    mtime
  } = stats;
  console.log(mtime);
});

to call fs.stat with the path of the file that we want to get the last modified date for asynchronously.

And we get the last modified date of the file with the mtime property from the stats object in the callback.

We can do the same thing synchronously with statSync:

const stats = fs.statSync("/dir/file.txt");
const {
  mtime
} = stats;
console.log(mtime);

We call statSync with the path of the file and the stats are returned synchronously.
