how to use the emptydir function from the fs-extra library in typescript

To use the emptydir function from the fs-extra library in TypeScript, first you need to install the package via npm:

npm install --save fs-extra

Then, in your TypeScript file, import the function as follows:

index.ts
import { emptyDir } from 'fs-extra';

2 lines

You can then use the emptyDir function to delete the contents of a directory. Here's an example:

index.ts
const dirPath = './path/to/your/directory';

// Deletes the contents of the directory
emptyDir(dirPath)
  .then(() => console.log(`Deleted contents of ${dirPath}`))
  .catch(err => console.error(err));

7 lines

The emptyDir function returns a Promise that resolves once the directory has been emptied or rejects if an error occurs.

Note that if the directory does not exist, the emptyDir function will not throw an error but will simply resolve without doing anything. If you need to create the directory if it does not exist, you can use the mkdirs function from fs-extra to create it first:

index.ts
import { emptyDir, mkdirs } from 'fs-extra';

const dirPath = './path/to/your/directory';

// Creates the directory if it does not exist and then deletes its contents
mkdirs(dirPath)
  .then(() => emptyDir(dirPath))
  .then(() => console.log(`Deleted contents of ${dirPath}`))
  .catch(err => console.error(err));

This will ensure that the directory exists before attempting to delete its contents.
