How to implement drag and drop functionality in Vue?
Jul 27, 2025 am 02:36 AM
Use native HTML5 drag and drop for simple cases by setting draggable="true", handling dragstart to set data via event.dataTransfer.setData(), and preventing default in dragover to allow dropping; 2. For lists or complex interactions, use vue-draggable-next with SortableJS, install via npm, bind v-model to the list, use item-key with objects, and leverage built-in events like @start and @end for drag lifecycle; 3. Always prevent default in dragover, store data properly using setData/getData, and avoid direct mutation of dataTransfer, as small errors can break functionality, making native suitable for basics and vue-draggable-next ideal for advanced use cases like Kanban boards or multi-list reordering.
Implementing drag and drop in Vue depends on whether you're using vanilla HTML5 drag and drop APIs or a third-party library. Here’s how to do it both ways — from basics to practical usage.
? Using Native HTML5 Drag and Drop (No Dependencies)
This approach uses the browser’s built-in drag, dragover, drop, etc., events. It works well for simple use cases.
1. Make an Element Draggable
Set the draggable attribute and handle the dragstart event:
<template>
<div>
<!-- Draggable Item -->
<div
class="draggable"
draggable="true"
@dragstart="onDragStart($event, item)"
>
{{ item.text }}
</div>
<!-- Drop Zone -->
<div
class="drop-zone"
@dragover.prevent
@drop="onDrop($event)"
>
Drop here
</div>
</div>
</template>
<script>
export default {
data() {
return {
item: { id: 1, text: 'Drag me!' },
draggedItem: null
}
},
methods: {
onDragStart(event, item) {
event.dataTransfer.setData('item', JSON.stringify(item));
this.draggedItem = item;
},
onDrop(event) {
const item = JSON.parse(event.dataTransfer.getData('item'));
console.log('Dropped:', item);
// Handle logic here (e.g., add to list, reorder, etc.)
}
}
}
</script>
<style>
.draggable {
padding: 10px;
background: #007bff;
color: white;
border-radius: 4px;
cursor: move;
}
.drop-zone {
margin-top: 20px;
padding: 40px;
background: #f0f0f0;
border: 2px dashed #ccc;
text-align: center;
}
</style>? Note:
@dragover.preventis crucial — without it, thedropevent won’t fire because the default behavior (no drop allowed) is not prevented.
? Using a Library: vue-draggable-next (Recommended for Lists)
For reordering lists or complex drag-and-drop interactions, use SortableJS via vue-draggable-next, which works with Vue 3 (also has Vue 2 support).
Install
npm install vue-draggable-next
Use in Component
<template>
<div>
<h3>Draggable List</h3>
<draggable
v-model="items"
tag="ul"
item-key="id"
@start="dragStart"
@end="dragEnd"
>
<template #item="{ element }">
<li>{{ element.text }}</li>
</template>
</draggable>
</div>
</template>
<script setup>
import { ref } from 'vue';
import draggable from 'vue-draggable-next';
const items = ref([
{ id: 1, text: 'Item 1' },
{ id: 2, text: 'Item 2' },
{ id: 3, text: 'Item 3' }
]);
function dragStart() {
console.log('Drag started');
}
function dragEnd() {
console.log('Drag ended');
// items are automatically reordered due to v-model binding
}
</script>
<style scoped>
ul {
list-style: none;
padding: 0;
}
li {
padding: 10px;
margin: 5px 0;
background: #eee;
cursor: move;
}
</style>? Benefits:
- Reordering lists with smooth animation
- Supports drag between multiple lists
- Touch support for mobile
- Works with Vue transitions
? Key Tips
- Always use
event.preventDefault()indragoverto allow dropping. - Store data in
dataTransferusingsetData()andgetData(). - For complex UIs (like Kanban boards),
vue-draggable-nextsaves time. - You can combine native drag for custom behavior and libraries for lists.
? Common Pitfalls
- Forgetting
@dragover.prevent→ drop won’t work. - Not setting
item-keyin<draggable></draggable>when usingv-modelwith objects. - Trying to mutate
dataTransferdirectly — only usesetData/getData.
Basically, go native for simple cases, use vue-draggable-next for lists or advanced interactions. It’s not complex, but small mistakes break the whole flow.

What is headless UI in Vue?
Jul 08, 2025 am 01:38 AM
HeadlessUIinVue refers to a library of UI components that provide no preset styles and only contains core logic and behavior. Its features include: 1. No style restrictions, developers can customize the design; 2. Focus on barrier-free and interactive logic, such as keyboard navigation, state management, etc.; 3. Support Vue framework integration, exposing the control interface through combinable functions or components. Reasons for use include: maintaining design consistency, built-in accessibility, strong component reusability, and lightweight library size. In practical applications, developers need to write HTML and CSS themselves. For example, when building a drop-down menu, the library handles state and interaction, while developers decide on visual presentation. Mainstream libraries include HeadlessUI and RadixVue for TailwindLabs, suitable for
How to watch nested properties in Vue 3?
Jul 07, 2025 am 12:51 AM
In Vue3, there are three ways to monitor nested properties using the watch function: 1. Use the getter function to accurately monitor specific nested paths, such as watch(()=>someObject.nested.property,callback); 2. Add the {deep:true} option to deeply monitor changes within the entire object, which is suitable for situations where the structure is complex and does not care about which property changes; 3. Return an array in the getter to listen to multiple nested values ??at the same time, which can be used in combination with deep:true; in addition, if ref is used, the nested properties in its .value need to be tracked through getter.

Building a Vue component library requires designing the structure around the business scenario and following the complete process of development, testing and release. 1. The structural design should be classified according to functional modules, including basic components, layout components and business components; 2. Use SCSS or CSS variables to unify the theme and style; 3. Unify the naming specifications and introduce ESLint and Prettier to ensure the consistent code style; 4. Display the usage of components on the supporting document site; 5. Use Vite and other tools to package as NPM packages and configure rollupOptions; 6. Follow the semver specification to manage versions and changelogs when publishing.
Key differences between Vue 2 and Vue 3?
Jul 09, 2025 am 01:29 AM
Vue3 has improved in many key aspects compared to Vue2. 1.Composition API provides a more flexible logical organization method, allowing centralized management of related logic, while still supporting Vue2's Options API; 2. Better performance and smaller package size, the core library is reduced by about 30%, the rendering speed is faster and supports better tree shake optimization; 3. The responsive system uses ES6Proxy to solve the problem of unable to automatically track attribute addition and deletion in Vue2, making the responsive mechanism more natural and consistent; 4. Built-in better support for TypeScript, support multiple node fragments and custom renderer API, improving flexibility and future adaptability. Overall, Vue3 is a smooth upgrade to Vue2,

It is recommended to use Vite to create Vue3 projects because it uses the browser's native ES module support and has a fast startup speed in development mode. 1. Make sure to install Node.js (16.x or higher) and npm/yarn/pnpm; 2. Run npmcreatevite@latestmy-vue-app--templatevue initialization project; 3. Follow the prompts to select TypeScript, VueRouter and other configurations; 4. Execute cdmy-vue-app and npminstall installation dependencies; 5. Use npmrundev to start the development server. Optional configurations include automatic browser opening, proxy settings, alias paths, and packaging optimizations. Recommended insurance
How to define routes in vue router?
Jul 05, 2025 am 12:58 AM
Defining routes in Vue projects requires understanding the structure and configuration. The steps are as follows: 1. Install and introduce vue-router, create a routing instance, and pass in a routes array containing path and component; 2. Use dynamic routing matching such as /user/:id to obtain parameters; 3. Use children attribute to implement nested routes; 4. Name the routes with the name attribute for jumping; 5. Use redirect for path redirect. After mastering these core points, you can configure routing efficiently.
Benefits of using ?
Jul 08, 2025 am 12:20 AM
? in regular expressions are used to convert greedy matches to non-greedy, achieving more accurate matches. 1. It makes the content as little as possible to match as little as possible to avoid mismatch across tags or fields; 2. It is often used in scenarios such as HTML parsing, log analysis, URL extraction, etc. that require precise control of the scope; 3. When using it, it is necessary to note that not all quantifiers are applicable. Some tools need to manually enable non-greedy mode, and complex structures need to be combined with grouping and assertions to ensure accuracy. Mastering this technique can significantly improve text processing efficiency.
