3. User interaction handling: Manages user interactions like input, paste, and keyboard events for smooth navigation and value management within the input boxes.
4. Focus management: Automatically focuses on the appropriate input box based on user actions.
5. Clear function: Clears all input boxes and resets the internal state.
6. Destroy function: Removes the OTP field element from the DOM.

Installation

• Install the package via npm:

  npm i @satyam-seth/otp-field

• Install the package via npm:

  yarn add @satyam-seth/otp-field

Usage

1. Import the OTPField class:

import { OTPField } from 'otp-field';

2. Define the configuration for your OTP field:

const otpFieldConfig = {
  namespace: 'otp', // Namespace for IDs (used for styling)
  boxCount: 6, // Number of input boxes
  // valueType: OTPValueType.NUMERIC, // Input type (numeric, alphabetic, alphanumeric)
  // customRegex: /your_custom_regex/, // Custom validation regex
  // onPasteBlur: true, // Blur the input box after pasting (default: true)
};

3. Create an instance of the OTPField class with the configuration:

const otpField = new OTPField(otpFieldConfig);

4. Build the OTP field and append it to the desired element in your DOM:

const containerElement = document.getElementById('otp-container');
otpField.build(containerElement);

5. Access the current OTP value entered by the user:

const otpValue = otpField.value;

6. SCSS import for styling:

@import '../../node_modules/@satyam-seth/otp-field/src/scss/field';

@include otp-field;

• Note: You can apply CSS classes like error, success, and warning to the div.otp-field container for state-specific theming.
