Headless UI in Vue

Introduction

Headless UI is a library designed to help developers create accessible UI components without worrying about styling. This lesson will explore how to integrate Headless UI with Vue.js, allowing for the development of modern, flexible applications.

What is Headless UI?

Headless UI provides a set of unstyled, fully accessible UI components that can be styled according to your design system. This approach separates the logic of the component from its presentation, enabling greater flexibility in design.

Key Concepts

• Accessibility: Components are designed with accessibility in mind.
• Separation of Concerns: Logic and styling are decoupled.
• Reusability: Components can be reused across projects with different styles.

Benefits of Headless UI

• Enhanced Accessibility: Built-in ARIA attributes.
• Customizable Styles: Style components as per your requirements.
• Improved Developer Experience: Focus on functionality rather than styling.

Setting Up Headless UI in Vue

Step 1: Install Headless UI

Use npm or yarn to install the Headless UI package.

npm install @headlessui/vue

Step 2: Create a Component

Here's an example of how to create a dropdown component using Headless UI in Vue:

<template>
  <Listbox v-model="selected">
    <ListboxButton>{{ selected.name }}</ListboxButton>
    <ListboxOptions>
      <ListboxOption v-for="option in options" :key="option.id" :value="option">
        {{ option.name }}
      </ListboxOption>
    </ListboxOptions>
  </Listbox>
</template>

<script>
import { Listbox } from '@headlessui/vue';

export default {
  components: { Listbox },
  data() {
    return {
      selected: { id: 1, name: 'Option 1' },
      options: [
        { id: 1, name: 'Option 1' },
        { id: 2, name: 'Option 2' },
        { id: 3, name: 'Option 3' },
      ],
    };
  },
};
</script>
