VanillaJS Smart Wizard is a step wizard plugin that does not require jQuery and is written in pure JavaScript. Its purpose is to provide a clean, elegant, and functional user interface for processes such as forms, checkouts, and registrations.

The project has been completely rewritten to remove the jQuery dependency, making it lighter, faster, and more modern. It supports ESM and CommonJS and works in all modern browsers. Additionally, it is designed with a responsive approach and is compatible with Bootstrap.

The plugin is compatible with the main JavaScript module systems, making it easy to integrate into any modern project. Below are initialization examples for ESM (ECMAScript Modules) and CommonJS.

#### Initialization with ES Modules (ESM)

For projects using a bundler like Vite, Webpack, or Rollup, the ESM approach is the most common. First, make sure the plugin is installed in your project.

``javascript
import SmartWizard from 'vanillajs-smartwizard';
import 'vanillajs-smartwizard/css'; // Or the direct path depending on the bundler

// Wizard initialization
const wizard = new SmartWizard('#smartwizard', {
selected: 0,
theme: 'arrows', // Example custom theme
toolbar: {
position: 'bottom',
},
// Other options...
});

// Example of using a public method
document.getElementById('nextButton').addEventListener('click', () => {
wizard.next();
});
`

#### Initialization with CommonJS

`javascript
/ Common JS /
const SmartWizard = require('vanillajs-smartwizard');
/**
*
* Remember, you must import de CSS file
*
*
*/
// Make sure the HTML is loaded before initializing
document.addEventListener('DOMContentLoaded', () => {
// Wizard initialization
const wizard = new SmartWizard('#smartwizard', {
selected: 0,
theme: 'arrows',
});

// Example of use
document.getElementById('prevButton').addEventListener('click', () => {
wizard.prev();
});
});
`
