copy a json file in typescript

To copy a JSON file in TypeScript, you can make use of the built-in fs module in Node.js. Specifically, you can use the copyFile method to copy the contents of one file to another.

Here's an example code snippet:

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

const sourceFile = 'path/to/source.json';
const destinationFile = 'path/to/destination.json';

fs.copyFile(sourceFile, destinationFile, (err) => {
  if (err) throw err;
  console.log('JSON file copied successfully!');
});

In this example, we import the fs module and define the paths to the source and destination JSON files. We then call the copyFile method, passing in the source and destination file paths, as well as a callback function that handles any errors that may occur.

Once the copy is complete, the callback function will be called and a message will be logged to the console indicating that the copy was successful.
