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

The fs-extra library provides additional functionality to the Node.js file system module. Here's an example of how to use the constructor function from the fs-extra library in TypeScript:

index.ts
import * as fs from 'fs-extra';

class MyClass {
  private myFilePath: string;

  constructor(filePath: string) {
    this.myFilePath = filePath;
    const myFile = new fs.createWriteStream(filePath);
    myFile.on('open', () => {
      console.log(`File ${this.myFilePath} opened successfully!`);
    });
    myFile.on('error', (err) => {
      console.error(`Error occurred while opening file ${this.myFilePath}: ${err}`);
    });
  }
}

In this example, fs is imported using the wildcard syntax as fs-extra. The MyClass constructor takes a file path as its argument and initializes a private myFilePath property. The createWriteStream() method creates a writable stream to the specified filePath. The on('open', …) and on('error', …) event listeners are used to handle both success and error scenarios while opening a file.

Note that in TypeScript, you need to include @types/fs-extra as a dependency in your project to get type definitions for fs-extra.
