nodejs fs directory exists

To check if a directory exists in Node.js using the fs module, you can follow these steps:

1. Import the fs module: Begin by importing the fs module, which is a built-in module in Node.js, using the require function. This will allow you to access the file system methods provided by the module.

2. Use the fs.stat method: The fs.stat method is used to retrieve information about a file or directory. Pass the path of the directory you want to check as the first argument to this method. You can provide the path as a string or use the path module to handle file paths more efficiently.

3. Check the stats object: The fs.stat method returns a stats object that contains information about the file or directory. To determine if the directory exists, you can access the stats.isDirectory() method. This method returns a boolean value indicating whether the path refers to a directory.

4. Handle the result: Based on the boolean value returned by stats.isDirectory(), you can take appropriate actions. If it returns true, the directory exists. If it returns false, the directory does not exist.

Here is an example code snippet that demonstrates the above steps:

const fs = require('fs');

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

fs.stat(directoryPath, (err, stats) => {
  if (err) {
    // Handle error if the directory does not exist or any other error occurs
    console.error('Error occurred:', err);
    return;
  }

  if (stats.isDirectory()) {
    console.log('The directory exists.');
  } else {
    console.log('The directory does not exist.');
  }
});

Note: Make sure to replace /path/to/directory with the actual path of the directory you want to check.
