主要记录Vant的一些配置，关于vue怎么安装、更新、创建项目等问题可以直接看官方文档，而且3.0是有UI控制台的，创建项目都是可视化的，很方便。
安装Vant
Vant - 轻量、可靠的移动端 Vue 组件库
npm i vant -S主要说下按需引用、REM适配、定制主题，因为官网的描述感觉还是太简单了，对于刚开始用还是需要一点时间的。
按需引用
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 babel-plugin-import 插件
npm i babel-plugin-import -D然后打开项目，对 babel.config.js 进行修改
module.exports = {
plugins: [
['import', {
libraryName: 'vant',
libraryDirectory: 'es',
style: true //上图中我是配置了定制主题的
}, 'vant']
]
};然后就可以在组件中使用了
import { Button, Cell, NavBar } from "vant";
export default {
components: {
[Button.name]: Button,
[Cell.name]: Cell,
[NavBar.name]: NavBar
}
};Rem 适配
Vant 中的样式默认使用px作为单位，如果需要使用rem单位，推荐使用以下两个工具
postcss-pxtorem 是一款 postcss 插件，用于将单位转化为 rem
lib-flexible 用于设置 rem 基准值
安装插件
//postcss-pxtorem
npm install postcss-pxtorem --save-dev
//lib-flexible
npm i -S amfe-flexible修改babel.config.js文件
module.exports = {
presets: ["@vue/app"],
plugins: [
[
"import",
{
libraryName: "vant",
libraryDirectory: "es",
style: name => `${name}/style/less`
},
"vant"
]
]
};修改vue.config.js文件，没有这个文件就新建一个
const autoprefixer = require("autoprefixer");
const pxtorem = require("postcss-pxtorem");
module.exports = {
// outputDir: "docs",
// publicPath: process.env.NODE_ENV === "production" ? "/vant-demo/" : "/",
css: {
loaderOptions: {
postcss: {
plugins: [
autoprefixer(),
pxtorem({
rootValue: 37.5,
propList: ["*"]
})
]
}
}
}
};修改main.js文件
import "amfe-flexible";查看效果，页面中都变成了rem
定制主题
modifyVars: {
red: '#03a9f4',
blue: '#3eaf7c',
orange: '#f08d49',
'text-color': '#111'
}所有可用的颜色变量请参考官方的配置文件 配置文件。
这里我是把modifyVars的值放在了单独的文件中，这里随便你怎么做都可以,下面是我的van-custom-theme.js文件内容，这样方便点，要改什么直接改就好了。
