Introduction to DueUtil

DueUtil is a powerful utility library designed to simplify and enhance productivity and development by providing a wide range of APIs that cater to various needs. This article aims to provide an in-depth understanding of DueUtil, along with numerous examples to help you make the most out of this versatile tool.

Getting Started with DueUtil

To get started, you need to install DueUtil using npm:

  npm install dueutil

API Examples

Below are some of the most useful APIs provided by DueUtil, along with examples demonstrating their usage:

1. Date Formatting API

The Date Formatting API allows you to format dates in various ways.

  const dueutil = require('dueutil');
  let formattedDate = dueutil.formatDate(new Date(), 'YYYY-MM-DD');
  console.log(formattedDate); // Output: 2023-10-05

2. Data Validation API

This API helps in validating different types of data effortlessly.

  let isValidEmail = dueutil.validateEmail('test@example.com');
  console.log(isValidEmail); // Output: true

3. String Manipulation API

Manipulate and transform strings easily using this API.

  let capitalizedString = dueutil.capitalize('hello world');
  console.log(capitalizedString); // Output: Hello World

4. Array Operations API

Perform various array operations like finding the intersection, union, or difference between arrays.

  let array1 = [1, 2, 3];
  let array2 = [3, 4, 5];
  let intersection = dueutil.arrayIntersection(array1, array2);
  console.log(intersection); // Output: [3]

5. Object Utilities API

Work with objects more efficiently using these utilities.

  let obj = {a: 1, b: 2};
  let clonedObj = dueutil.cloneObject(obj);
  console.log(clonedObj); // Output: {a: 1, b: 2}

6. Async Helper API

Manage asynchronous operations with ease.

  async function fetchData() {
    let data = await dueutil.asyncFetch('https://api.example.com/data');
    console.log(data);
  }
  fetchData();

7. Number Utilities API

Perform various operations on numbers.

  let roundedNumber = dueutil.roundTo(5.678, 2);
  console.log(roundedNumber); // Output: 5.68

8. Regular Expression API

Create and use regular expressions more effectively.

  let regex = dueutil.createRegex('[a-z]+');
  console.log(regex.test('hello')); // Output: true

9. HTTP Request API

Make HTTP requests effortlessly.

  dueutil.httpGet('https://api.example.com/data', (response) => {
    console.log(response);
  });

10. Event Emitter API

Implement event-driven architecture using this API.

  let emitter = new dueutil.EventEmitter();
  emitter.on('event', () => {
    console.log('Event triggered');
  });
  emitter.emit('event');

Example Application Using DueUtil APIs

Here’s a simple example to demonstrate how to use multiple DueUtil APIs together in an application:

  const dueutil = require('dueutil');
  
  function app() {
    // Format a date
    let today = dueutil.formatDate(new Date(), 'DD/MM/YYYY');
    
    // Validate email
    let email = 'user@example.com';
    let isValidEmail = dueutil.validateEmail(email);
    
    // Capitalize a string
    let greeting = dueutil.capitalize('hello world');
    
    // Fetch data from an API
    dueutil.httpGet('https://api.example.com/data', (response) => {
      let data = response;
      
      // Process data using various DueUtil APIs
      let processedData = dueutil.cloneObject(data);
      
      console.log(`Today: ${today}`);
      console.log(`Is valid email: ${isValidEmail}`);
      console.log(`Greeting: ${greeting}`);
      console.log('Data:', processedData);
    });
  }
  
  app();

With these examples, you should have a strong foundation to start using DueUtil in your own projects, thereby improving your development efficiency and productivity.
