# Quickstart
|
||
|
||
## Install
|
||
|
||
### npm
|
||
|
||
```bash
|
||
# Install Vant 2 for Vue 2 project
|
||
npm i vant -S
|
||
|
||
# Install Vant 3 for Vue 3 project
|
||
npm i vant@next -S
|
||
```
|
||
|
||
### CDN
|
||
|
||
The easiest way to use Vant is to include a CDN link in the html file, after which you can access all components via the global variable `vant`.
|
||
|
||
```html
|
||
<!-- import style -->
|
||
<link
|
||
rel="stylesheet"
|
||
href="https://cdn.jsdelivr.net/npm/vant@2.12/lib/index.css"
|
||
/>
|
||
|
||
<!-- import script -->
|
||
<script src="https://cdn.jsdelivr.net/npm/vue@2.6/dist/vue.min.js"></script>
|
||
<script src="https://cdn.jsdelivr.net/npm/vant@2.12/lib/vant.min.js"></script>
|
||
|
||
<script>
|
||
// Render the Button component
|
||
new Vue({
|
||
el: '#app',
|
||
template: `<van-button>Button</van-button>`,
|
||
});
|
||
|
||
// Call function component
|
||
vant.Toast('Message');
|
||
|
||
// Register Lazyload directive
|
||
Vue.use(vant.Lazyload);
|
||
</script>
|
||
```
|
||
|
||
#### Free CDN
|
||
|
||
You can use Vant through these free CDN services:
|
||
|
||
- [jsdelivr](https://www.jsdelivr.com/package/npm/vant)
|
||
- [cdnjs](https://cdnjs.com/libraries/vant)
|
||
- [unpkg](https://unpkg.com/)
|
||
|
||
Note: Free CDN is generally used for making prototypes or personal projects. It is not recommended to use free CDN in production environment.
|
||
|
||
For enterprise developers, we recommend:
|
||
|
||
- install with npm, use build tools to bundle it
|
||
- download the scripts, host it on your own server
|
||
|
||
### CLI
|
||
|
||
We recommend to use [Vue Cli](https://cli.vuejs.org/) to create a new project.
|
||
|
||
```bash
|
||
# Install Vue Cli
|
||
npm install -g @vue/cli
|
||
|
||
# Create a project
|
||
vue create hello-world
|
||
|
||
# Open GUI
|
||
vue ui
|
||
```
|
||
|
||
|
||
|
||
In the GUI, click on 'Dependencies' -> `Install Dependencies` and add `vant` to the dependencies.
|
||
|
||
## Usage
|
||
|
||
### 1. Import on demand
|
||
|
||
Use [babel-plugin-import](https://github.com/ant-design/babel-plugin-import) to import components on demand.
|
||
|
||
```bash
|
||
# Install plugin
|
||
npm i babel-plugin-import -D
|
||
```
|
||
|
||
```js
|
||
// set babel config in .babelrc or babel-loader
|
||
// Note: Don't set libraryDirectory if you are using webpack 1.
|
||
{
|
||
"plugins": [
|
||
["import", {
|
||
"libraryName": "vant",
|
||
"libraryDirectory": "es",
|
||
"style": true
|
||
}]
|
||
]
|
||
}
|
||
|
||
// For users who use babel7, that can be configured in babel.config.js
|
||
module.exports = {
|
||
plugins: [
|
||
['import', {
|
||
libraryName: 'vant',
|
||
libraryDirectory: 'es',
|
||
style: true
|
||
}, 'vant']
|
||
]
|
||
};
|
||
```
|
||
|
||
```js
|
||
// Then you can import components from vant
|
||
import { Button } from 'vant';
|
||
```
|
||
|
||
> If you are using TypeScript，please use [ts-import-plugin](https://github.com/Brooooooklyn/ts-import-plugin) instead.
|
||
|
||
### 2. Manually import
|
||
|
||
```js
|
||
import Button from 'vant/lib/button';
|
||
import 'vant/lib/button/style';
|
||
```
|
||
|
||
### 3. Import all components
|
||
|
||
```js
|
||
import Vue from 'vue';
|
||
import Vant from 'vant';
|
||
import 'vant/lib/index.css';
|
||
|
||
Vue.use(Vant);
|
||
```
|
||
|
||
> If you configured babel-plugin-import, you won't be allowed to import all components.
