move a csv file in typescript

To move a CSV file in TypeScript, we can use the fs module to read the contents of the file and then use the fs module again to move the file to a new location.

Here is an example:

index.ts
import fs from 'fs';
import csvParser from 'csv-parser';
import path from 'path';

const oldFilePath = 'path/to/old/file.csv';
const newFilePath = 'path/to/new/file.csv';

// Read the contents of the CSV file
fs.createReadStream(oldFilePath)
  .pipe(csvParser())
  .on('data', (data) => {
    // Do something with the data
  })
  .on('end', () => {
    // Move the file to a new location
    fs.rename(oldFilePath, newFilePath, (err) => {
      if (err) throw err;
      console.log('File moved successfully!');
    });
  });

In this example, we first define the old and new file paths. We then use fs.createReadStream to read the contents of the old file and csv-parser to parse the CSV data. We can then do whatever we need to do with the data.

Finally, we use fs.rename to move the old file to the new path. The rename function takes three arguments: the old file path, the new file path, and a callback function that is called when the move is complete. If an error occurs during the move, the error will be thrown.
