The fs.Dir.close() method is an inbuilt application programming interface of class fs.Dir with in File System module which is used to close the directory’s underlying resource handle asynchronously.
Syntax:
const dir.close()
Parameter: This method does not accept any parameter.
Return Value: This method returns the promise which is just an enhancement to callback functions stop().
Below programs illustrates the use of fs.Dir.close() method in Node.js
Example 1:
Filename: GFG.js
// Node program to demonstrate the // dir.close() method const fs = require( 'fs' );
// Initiating async function async function stop(path) {
// Creating and initiating directory's
// underlying resource handle
const dir = await fs.promises.opendir(path);
// Asynchronously closing the directory's
// underlying resource handle
const promise = dir.close();
// Display the result
console.log(promise);
} // Catching error stop( './' ). catch (console.error);
|
Run GFG.js file using the following command:
node GFG.js
Output:
Example 2:
// Node program to demonstrate the // dir.close() API const fs = require( 'fs' );
// Initiating async function async function stop(path) {
let dir = null ;
try {
// Creating and initiating directory's
// underlying resource handle
dir = await fs.promises.
opendir( new URL('file: ///F:/java/'));
} finally {
if (dir) {
// Display the result
console.log( "dir is closed successfully" );
// Close the file if it is opened.
await dir.close();
}
}
} // Catching error stop('./'). catch (console.error);

Run GFG.js file using the following command:
node GFG.js
Output:
Note: The above program will not run on online JavaScript and script editor.
