find the name of a csv file in typescript

To find the name of a CSV file in TypeScript, you first need to import the Node.js File System module and the path module. The path module provides methods for working with file and directory paths, and the File System module provides methods for interacting with the file system.

Then, you can use the path.basename() method to extract the name of the file from a given file path. Here is an example:

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

const filePath = 'path/to/myFile.csv';
const fileName = path.basename(filePath);

console.log(fileName); // 'myFile.csv'
178 chars
8 lines

In this example, we first define the file path to our CSV file. Then we use the path.basename() method to extract the name of the file from the file path. Finally, we log the file name to the console.
