copy a csv file in typescript

To copy a CSV file in TypeScript, you'll need to use the Node.js fs (filesystem) module. Here's an example code snippet that demonstrates how to copy a CSV file:

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

const sourceFilePath = 'path/to/source.csv';
const destFilePath = 'path/to/destination.csv';

// Read the contents of the source file
const fileContent = fs.readFileSync(sourceFilePath, 'utf-8');

// Write the contents to the destination file
fs.writeFileSync(destFilePath, fileContent);

console.log('CSV file copied successfully.');

In this example, we import the fs module and assign the file paths for the source and destination files. We then read the contents of the source file using fs.readFileSync() and assign them to a variable called fileContent.

Finally, we use fs.writeFileSync() to write the contents of fileContent to the destination file. After the file is copied, we log a success message to the console.

Note that this example assumes that the source file exists and that the destination file does not exist yet. If the destination file already exists, its contents will be overwritten when you write to it using fs.writeFileSync(). If you need to copy the file but also avoid overwriting the destination, you'll need to implement a different solution that checks for the existence of the destination file before copying.
