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

To use the realpath function from the fs-extra module in Node.js, you will need to first install fs-extra using NPM. You can do that by running the following command in your terminal:

npm install fs-extra

Once you have fs-extra installed, you can use the realpath function to get the real path of a file or directory. Here is an example:

index.tsx
const fs = require('fs-extra');
const path = require('path');

const filePath = './myFile.txt';

fs.realpath(filePath, (err, resolvedPath) => {
  if (err) {
    console.error(err);
    return;
  }

  console.log(resolvedPath);
  console.log(path.resolve(resolvedPath));
});

In this example, we first require the fs-extra and path modules. We then define the path of the file we want to get the real path for (./myFile.txt in this case).

Next, we call the realpath function and pass in the filePath variable as the first argument. The realpath function takes a callback function as its second argument, which will be called with the real path of the file.

If there is an error getting the real path, the err parameter will be set to an error object. Otherwise, the resolvedPath parameter will contain the real path of the file.

Lastly, we log the real path to the console, as well as the resolved path using the path.resolve function.
