Once the installation is complete, you can import the fs-extra library and use the ensureLink function like this:

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

// creates a symbolic link from sourceFile to destFile
fs.ensureLink(sourceFile, destFile, (err) => {
  if (err) {
    console.error(err);
  } else {
    console.log('Symbolic link created successfully!');
  }
});

The ensureLink function takes three arguments:

1. sourceFile - A string that specifies the path to the source file.
2. destFile - A string that specifies the path to the destination file, which will be the symbolic link.
3. callback - A function that will be called once the symbolic link is created or an error occurs. The callback function takes one argument, which will be an error object if an error occurs during the link creation process, or null if the link is created successfully.

Note that the ensureLink function will only create a symbolic link if one doesn't already exist at the destination path. If a symbolic link already exists, it will not be overwritten.
