find the size of a csv file in typescript

To find the size of a CSV file in TypeScript, you can use the Node.js built-in module 'fs' and its function 'statSync'. Here is an example code snippet that shows how to implement this:

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

const filePath = './data.csv';

// Get the file size in bytes
const fileSizeInBytes = fs.statSync(filePath).size;

// Convert the file size from bytes to kilobytes and round to two decimal places
const fileSizeInKB = (fileSizeInBytes / 1024).toFixed(2);

console.log(`The size of ${filePath} is ${fileSizeInKB} KB`);

In the code above, we first import the 'fs' module. Then, we define the path of our CSV file in the 'filePath' variable.

Next, we use the 'statSync' method to get the file information, including the file size in bytes. We save this value in the 'fileSizeInBytes' variable.

Finally, we convert the file size from bytes to kilobytes by dividing it by 1024 and round it to two decimal places using the 'toFixed' method. We store this value in the 'fileSizeInKB' variable, and print it to the console along with the original file path.
