find the parent directory of a file in typescript

To find the parent directory of a file in TypeScript using Node.js, you can use the built-in path and fs modules. Here's an example code snippet that demonstrates how this can be done:

index.ts
import { dirname } from 'path';
import { fileURLToPath } from 'url';
import * as fs from 'fs';

const __filename = fileURLToPath(import.meta.url);
const __dirname = dirname(__filename);

const file = '/path/to/my/file.txt';
const filePath = `${__dirname}${file}`;

fs.stat(filePath, (err, stats) => {
  if (err) {
    console.error(err);
    return;
  }

  const parentDir = dirname(filePath);
  console.log(`The parent directory of ${file} is ${parentDir}`);
});

In this example, we first define the path to the file using the __dirname global variable and the file's relative path. We then use the fs.stat() method to get information about the file, including its size and modification time. Finally, we use the dirname() method from the path module to get the parent directory of the file, and log it to the console.
