how to use the opendirsync function from fs-extra in javascript

To use the opendirSync function from the fs-extra package in JavaScript, first, you need to install the fs-extra package using npm. You can do this by running the following command in your terminal:

index.tsx
npm install fs-extra

After installing the package, you can import the fs-extra module in your JavaScript file and call the opendirSync function to open a directory synchronously. Here's an example code snippet:

const fs = require('fs-extra');

const dirPath = '/path/to/directory';

try {
  const dir = fs.opendirSync(dirPath);

  console.log(`Directory successfully opened: ${dirPath}`);
  console.log('Directory contents:');

  let dirent;
  while ((dirent = dir.readSync()) !== null) {
    console.log(dirent.name);
  }

  dir.closeSync();
} catch (err) {
  console.error(`Error opening directory: ${dirPath}`, err);
}

In this code snippet, we first import the fs-extra package and define the path of the directory to be opened. We then use a try-catch block to catch any errors that might occur when opening the directory.

If the directory is opened successfully, we use a while loop to read the directory contents using the readSync method of the dir object. We print the names of all the files and directories inside the directory to the console.

Finally, we use the closeSync method to close the directory.

Note that the opendirSync function is only available in Node.js v12.12.0 and above. If you're using an earlier version of Node.js, you can use the readdirSync method of the fs module to read the contents of a directory synchronously.
