find the parent directory of a directory in typescript

To find the parent directory of a directory in Typescript, you can use the 'path' and 'fs' modules provided by Node.js. Here's a code snippet that demonstrates how to achieve this:

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

const directoryPath = "/path/to/your/directory";

try {
  const parentDirPath = path.dirname(directoryPath);
  const parentDirStats = fs.statSync(parentDirPath);
  
  if (parentDirStats.isDirectory()) {
    console.log(`The parent directory of ${directoryPath} is ${parentDirPath}`);
  }
} catch (err) {
  console.error(err);
}

In this example, we first import the 'path' and 'fs' modules. We then define the path to the directory we want to find the parent of.

We use the 'path.dirname()' function to get the parent directory path, and then use 'fs.statSync()' to get information about the directory. We check if the path is a directory using 'fs.statSync().isDirectory()' and then log the result to the console.

Note: Since this code uses synchronous file system functions, it may block the event loop while executing, so be careful when using this in a production environment.
