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

To use the copyFileSync function from the fs-extra library in TypeScript, you will first need to install the fs-extra package along with its types using npm:

index.ts
npm install --save fs-extra @types/fs-extra

Then, you can import the copyFileSync function into your TypeScript file and use it as follows:

index.ts
import * as fsExtra from 'fs-extra';

try {
  fsExtra.copyFileSync('source/file.txt', 'destination/file.txt');
  console.log('File was copied successfully!');
} catch (err) {
  console.error(err);
}

In the code above, we import the fs-extra module and call the copyFileSync function with two arguments: the source file path and the destination file path. We wrap the function call in a try-catch block to handle any errors that may occur, and we log to the console when the file is successfully copied.

Make sure to also include the fs module in your TypeScript file, as fs-extra is built on top of it and uses it internally:

index.ts
import * as fs from 'fs';
