Vue移动端组件库Vant的快速上手

曾经终败给现在 2023-02-10 05:08 180阅读 0赞

1.   初次创建项目使用此方法

> Vue 官方提供的脚手架 [Vue Cli][] 创建项目

*  安装

npm install -g @vue/cli

运行

vue ui

![format_png][]

2. 已有项目 使用Vant

安装

npm i vant --save

引入组件配置

**方式一. 自动按需引入组件 (推荐)**

> [babel-plugin-import][] 是一款 babel 插件，它会在编译过程中将 import 的写法自动转换为按需引入的方式

# 安装插件
    npm i babel-plugin-import -D

// 在.babelrc 中添加配置
    // 注意：webpack 1 无需设置 libraryDirectory
    {
      "plugins": [
        ["import", {
          "libraryName": "vant",
          "libraryDirectory": "es",
          "style": true
        }]
      ]
    }
    
    // 对于使用 babel7 的用户，可以在 babel.config.js 中配置
    module.exports = {
      plugins: [
        ['import', {
          libraryName: 'vant',
          libraryDirectory: 'es',
          style: true
        }, 'vant']
      ]
    };

// 接着你可以在代码中直接引入 Vant 组件
    // 插件会自动将代码转化为方式二中的按需引入形式
    import { Button } from 'vant';

查看package.json

babel.config.js里

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTIyOTU4OA_size_16_color_FFFFFF_t_70 2][]

使用先注册

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTIyOTU4OA_size_16_color_FFFFFF_t_70 3][]

使用

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTIyOTU4OA_size_16_color_FFFFFF_t_70 4][]

实际页面效果

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MTIyOTU4OA_size_16_color_FFFFFF_t_70 5][]

**方式二. 手动按需引入组件**

> 在不使用插件的情况下，可以手动引入需要的组件

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

**方式三. 导入所有组件**

> 在main.js中导入
> 
> Vant 支持一次性导入所有组件，引入所有组件会增加代码包体积，因此不推荐这种做法

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