Pros of vue-select

• Lighter weight and simpler API, making it easier to integrate and use
• More customizable appearance through scoped slots and CSS variables
• Better TypeScript support with full type definitions

Cons of vue-select

• Fewer built-in features compared to vue-multiselect (e.g., no tagging or grouping options)
• Less extensive documentation and examples
• Smaller community and fewer updates/maintenance

Code Comparison

vue-select:

<v-select
  v-model="selected"
  :options="options"
  :reduce="option => option.code"
  label="name"
/>

vue-multiselect:

<multiselect
  v-model="selected"
  :options="options"
  :custom-label="option => option.name"
  track-by="code"
  :multiple="true"
/>

Both libraries offer similar core functionality for creating select components in Vue applications. vue-select focuses on simplicity and customization, while vue-multiselect provides more built-in features out of the box. The choice between them depends on the specific requirements of your project, such as the need for advanced features, TypeScript support, or a lighter-weight solution.

Pros of Keen-UI

• Offers a comprehensive set of UI components beyond just multiselect
• Provides a consistent design language across all components
• Includes accessibility features out of the box

Cons of Keen-UI

• Larger bundle size due to the full UI component library
• May require more setup and configuration for simple use cases
• Less focused on optimizing the multiselect component specifically

Code Comparison

Keen-UI multiselect usage:

<template>
  <ui-select
    v-model="selectedItems"
    :options="options"
    multiple
    placeholder="Select items"
  ></ui-select>
</template>

Vue-multiselect usage:

<template>
  <multiselect
    v-model="selectedItems"
    :options="options"
    :multiple="true"
    placeholder="Select items"
  ></multiselect>
</template>

Both libraries offer similar syntax for basic multiselect functionality. However, Keen-UI uses the ui-select component name, while Vue-multiselect uses multiselect. Keen-UI's approach is consistent with its other UI components, while Vue-multiselect focuses solely on the multiselect functionality.

Pros of vue-virtual-scroller

• Optimized for rendering large lists with improved performance
• Supports dynamic item heights and horizontal scrolling
• Provides smooth scrolling experience for large datasets

Cons of vue-virtual-scroller

• More complex implementation compared to vue-multiselect
• Requires additional setup for custom item rendering
• May have a steeper learning curve for beginners

Code Comparison

vue-virtual-scroller:

<template>
  <RecycleScroller
    class="scroller"
    :items="list"
    :item-size="32"
    key-field="id"
    v-slot="{ item }"
  >
    <div class="user">{{ item.name }}</div>
  </RecycleScroller>
</template>

vue-multiselect:

<template>
  <multiselect
    v-model="value"
    :options="options"
    :multiple="true"
    :close-on-select="false"
    placeholder="Pick some"
  ></multiselect>
</template>

vue-virtual-scroller is focused on efficiently rendering large lists with virtual scrolling, while vue-multiselect is designed for creating customizable dropdown selection components. The former is better suited for performance-critical applications with extensive data, while the latter offers a more straightforward solution for multi-select functionality.

Pros of Vue.Draggable

• Provides drag-and-drop functionality for list reordering
• Integrates seamlessly with Vue.js components
• Supports touch devices and works well on mobile

Cons of Vue.Draggable

• Limited to drag-and-drop functionality, not a full-featured select component
• May require additional styling and customization for complex use cases

Code Comparison

Vue.Draggable:

<draggable v-model="myArray">
  <div v-for="element in myArray" :key="element.id">
    {{ element.name }}
  </div>
</draggable>

vue-multiselect:

<multiselect
  v-model="value"
  :options="options"
  :multiple="true"
  :close-on-select="false"
  placeholder="Pick some"
></multiselect>

Summary

Vue.Draggable is focused on providing drag-and-drop functionality for list reordering, while vue-multiselect is a feature-rich select component with support for multiple selections, tagging, and searching. Vue.Draggable excels in its specific use case but lacks the versatility of vue-multiselect for complex selection scenarios. The choice between the two depends on the specific requirements of your project, with Vue.Draggable being ideal for sortable lists and vue-multiselect better suited for advanced selection interfaces.

Pros of vee-validate

• More comprehensive form validation solution
• Supports asynchronous and custom validation rules
• Integrates well with various UI frameworks and form inputs

Cons of vee-validate

• Steeper learning curve due to more complex API
• Potentially heavier bundle size for simpler use cases
• May require additional configuration for optimal performance

Code Comparison

vee-validate:

import { defineRule, Form, Field } from 'vee-validate';

defineRule('required', value => {
  if (!value || !value.length) {
    return 'This field is required';
  }
  return true;
});

vue-multiselect:

import Multiselect from 'vue-multiselect';

export default {
  components: { Multiselect },
  data() {
    return { value: null, options: ['Option 1', 'Option 2', 'Option 3'] }
  }
}

While vee-validate focuses on form validation with a more extensive API, vue-multiselect is specifically designed for creating customizable dropdown components. vee-validate offers greater flexibility for complex form scenarios, but vue-multiselect provides a simpler solution for multi-select functionality. The choice between the two depends on the specific requirements of your project, with vee-validate being more suitable for comprehensive form validation needs and vue-multiselect for specialized dropdown implementations.
