node if path exists

To check if a path exists in Node.js, you can use the fs module. Here are the steps to do so:

1. Import the fs module using the require function:

const fs = require('fs');

1. Use the fs.existsSync() method to check if a path exists. This method takes a path as an argument and returns a boolean value indicating whether the path exists or not. Here's an example:

const path = '/path/to/check';

if (fs.existsSync(path)) {
  console.log('Path exists');
} else {
  console.log('Path does not exist');
}

1. If the path exists, the code inside the if block will be executed. You can replace the console.log() statements with your desired logic or actions.

That's it! By following these steps, you can easily check if a path exists in Node.js using the fs module.
