how to use the copyfile function from the fs-extra library in typescript

The fs-extra library is a Node.js module that extends the fs module, providing extra functionality for file handling. The copyFile() function is one of these added functions, which allows you to copy a file from one location to another.

To use the copyFile() function in TypeScript, you can follow these steps:

Step 1: Install the fs-extra library

Step 3: Call the copyFile() function

index.ts
copyFile('/path/to/source/file', '/path/to/destination/file')
  .then(() => {
    console.log('File copied successfully!');
  })
  .catch((err) => {
    console.error(err);
  });

The copyFile() function takes two arguments: the path to the source file and the path to the destination file. It returns a Promise that resolves when the copy operation is complete. If the operation is unsuccessful, the Promise is rejected with an error.

Using this method, you can easily copy files in your TypeScript project using the fs-extra library.
