Introduction to Requizzle

Requizzle is a powerful JavaScript library that simplifies a variety of common web development tasks, from making HTTP requests to manipulating the DOM. Below, you’ll find an extensive guide to Requizzle’s most useful APIs, complete with code snippets and an example application to demonstrate their usage.

1. Making HTTP Requests

Requizzle abstracts the complexity of making HTTP requests. Here’s how you can use it to perform GET and POST operations:

  // GET request example
  requizzle.get('https://api.example.com/data')
    .then(response => console.log(response))
    .catch(error => console.error('Error:', error));
  
  // POST request example
  requizzle.post('https://api.example.com/data', {
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ key: 'value' })
  })
    .then(response => console.log(response))
    .catch(error => console.error('Error:', error));

2. Manipulating the DOM

Requizzle provides simple methods for DOM manipulation:

  // Select an element
  const element = requizzle.select('#myElement');
  
  // Add a class
  requizzle.addClass(element, 'active');
  
  // Remove a class
  requizzle.removeClass(element, 'inactive');
  
  // Set inner HTML content
  requizzle.html(element, '
Hello, world!
');

3. Event Handling

Handling events is straightforward with Requizzle:

  // Add click event listener
  requizzle.on('#myButton', 'click', () => {
    alert('Button clicked!');
  });
  
  // Remove click event listener
  requizzle.off('#myButton', 'click');

4. Utility Functions

Requizzle includes a variety of utility functions:

  // Debounce function
  const debouncedFunction = requizzle.debounce(() => {
    console.log('Debounced!');
  }, 300);
  
  // Throttle function
  const throttledFunction = requizzle.throttle(() => {
    console.log('Throttled!');
  }, 300);

Example Application

Let’s build a simple application that utilizes the above APIs:

  // HTML structure
  <div id="app">
    <input type="text" id="inputField" placeholder="Type something..." />
    <button id="submitBtn">Submit</button>
    <div id="output"></div>
  </div>

  // JavaScript code
  // Select elements
  const inputField = requizzle.select('#inputField');
  const submitBtn = requizzle.select('#submitBtn');
  const outputDiv = requizzle.select('#output');

  // Add event listener
  requizzle.on(submitBtn, 'click', () => {
    const value = inputField.value;

    // Update DOM
    requizzle.html(outputDiv, `
You typed: ${value}
`);

    // Clear input field
    inputField.value = '';
  });

This example integrates Requizzle APIs to handle user input and update the DOM dynamically.

With Requizzle, web development becomes intuitive and efficient, thanks to its comprehensive API coverage and simplicity.
