Quickstart

Install

npm

# Install vant 2.x for Vue 2 project
npm i vant -S

# Install vant 3.x 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.

<!-- import style -->
<link
  rel="stylesheet"
  href="https://cdn.jsdelivr.net/npm/vant@2.10/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@2.10/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>

CLI

We recomment to use Vue Cli to create a new project.

# 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 to import components on demand.

# Install plugin
npm i babel-plugin-import -D

// 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']
  ]
};

// Then you can import components from vant
import { Button } from 'vant';

If you are using TypeScript，please use ts-import-plugin instead.

2. Manually import

import Button from 'vant/lib/button';
import 'vant/lib/button/style';

3. Import all components

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.

Other

Rem units

Vant use px as size units by default，you can use tools such as postcss-pxtorem to transform units to rem.

PostCSS Config

postcss config example:

module.exports = {
  plugins: {
    autoprefixer: {
      browsers: ['Android >= 4.0', 'iOS >= 8'],
    },
    'postcss-pxtorem': {
      rootValue: 37.5,
      propList: ['*'],
    },
  },
};
