Vue is a popular JavaScript framework, and Vant is a mobile UI framework based on Vue. Its use is very convenient for Vue developers. In this article, we will explore how to use Vant.

1. Installing Vant

First, you need to install Vant in the project. This can be installed via the npm package manager. An initialized Vue project is defined. You can use the following command to install Vant:

npm install vant --save

2. Reference Vant

After completing the installation of Vant, we need to reference it in the Vue project it. In the main.js file, add the following code:

import Vue from 'vue';
import Vant from 'vant';
import 'vant/lib/index.css';

Vue.use(Vant);

This code snippet will import the Vant library from Vant's npm package and register it as a Vue plug-in, so that we can use Vant in the Vue program All components.

3. Using Vant components

After completing the installation and reference of Vant, you can start using all the UI components we provide. The following is an example:

<template>
  <van-button type="primary">Primary Button</van-button>
  <van-button type="info">Info Button</van-button>
</template>

<script>
  export default {
    name: 'MyComponent'
  }
</script>

<style>
  /* 添加需要的 style ，如需全局引入，可在 main.js 中 import */
  .van-button {
    margin-right: 10px;
  }
</style>

The above code defines a Vue component. The van-button component is used twice in the template. The type attribute of each component is set to primary and info to generate buttons respectively. At the same time, we also specified the style rules of the .van-button style in the style sheet.

4. Customize the theme

Vant provides us with a very simple way to customize the theme. Just define a new SCSS file (for example "my-theme.scss") and use it in your Vue project. The following code:

// 自定义颜色
$--color-primary: #f00;
$--color-success: #0f0;
$--color-warning: #ff0;
$--color-danger: #f50;
$--color-text-base-inverse: #fff;

// 引入 Vant 样式
@import '~vant/lib/index';

// 添加自己的样式
.my-button {
  background-color: $--color-primary;
  border-radius: 20px;
}

This file defines some custom styles and then uses the Vant style. At the same time, our style sheet also defines style rules.my-button. This rule specifies a background color and a 20-pixel rounded corner via $--color-primary.
