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

To use the link function from the fs-extra library in TypeScript, you can follow the steps below:

1. Import the fs-extra library and the promises object from the fs module, which provides a Promise-based API for working with the file system.

index.ts
import * as fs from 'fs';
import * as fse from 'fs-extra';
const { promises } = fs;

2. Define your source and target file paths. The link function creates a new hard link at the target path that points to the source path.

index.ts
const src = '/path/to/source/file';
const target = '/path/to/target/file';

3. Use the link function from fs-extra to create a hard link at the target path.

index.ts
fse.link(src, target)
  .then(() => console.log(`Linked ${src} to ${target}`))
  .catch(err => console.error(err));

This will create a new hard link at the target path that points to the source path. If successful, the console will log a message indicating that the link was created. If there is an error, it will be caught and logged to the console.
