Nuxt 使用 create-nuxt-app 创建项目时,选择使用 Element-UI 为默认组件库,发现 Nuxt 没有开启 Element-UI 的按需引入配置,需要自行配置。安装依赖安装依赖安装依赖在 create-nuxt-app 中没有选择 Element-UI 的先安装。
npm install element-ui --save
npm install element-ui --save或者
yarn add element-ui
yarn add element-uiElement-UI 开启按需引入,必须安装 babel-plugin-component 插件。
npm install babel-plugin-component --save-dev
npm install babel-plugin-component --save-dev或者
yarn add babel-plugin-component
yarn add babel-plugin-component安装完成后,在文件根目录创建(或已经存在) plugins/ 目录下创建相应的插件文件,创建名为:element-ui.js 的文件。
// element-ui.js
import Vue from 'vue'
import {
Container,
Header,
Aside,
Main,
Menu,
MenuItem,
Button,
Form,
FormItem,
Input
} from 'element-ui'
import locale from 'element-ui/lib/locale/lang/en'

const components = [
Container,
Header,
Aside,
Main,
Menu,
MenuItem,
Button,
Form,
FormItem,
Input
];

const Element = {
install (Vue) {
components.forEach(component => {

Vue.component(component.name, component)
})
}
}

Vue.use(Element, { locale })
// element-ui.js
import Vue from 'vue'
import {
Container,
Header,
Aside,
Main,
Menu,
MenuItem,
Button,
Form,
FormItem,
Input
} from 'element-ui'
import locale from 'element-ui/lib/locale/lang/en'

const components = [
Container,
Header,
Aside,
Main,
Menu,
MenuItem,
Button,
Form,
FormItem,
Input
];

const Element = {
install (Vue) {
components.forEach(component => {

Vue.component(component.name, component)
})
}
}

Vue.use(Element, { locale })配置 plugins 选项配置 plugins 选项配置 plugins 选项在 nuxt.config.js 文件中,配置 plugins 选项。
module.exports = {
/*
** Plugins to load before mounting the App
** https://nuxtjs.org/guide/plugins
*/
plugins: ["@/plugins/element-ui"],
}
module.exports = {
/*
** Plugins to load before mounting the App
** https://nuxtjs.org/guide/plugins
*/
plugins: ["@/plugins/element-ui"],
}Nuxt 默认为开启 SSR,采用服务端渲染,也可以手动配置关闭 SSR,配置为:
module.exports = {
/*
** Plugins to load before mounting the App
** https://nuxtjs.org/guide/plugins
*/
plugins: [
{

src: "@/plugins/element-ui",

ssr: false // 关闭ssr
}
],
}
module.exports = {
/*
** Plugins to load before mounting the App
** https://nuxtjs.org/guide/plugins
*/
plugins: [
{

src: "@/plugins/element-ui",

ssr: false // 关闭ssr
}
],
}如果在 create-nuxt-app 中默认选了 Element-UI 的,还需要将 Element-UI 的全局样式去掉,即在 nuxt.config.js 中:
module.exports = {
/*
** Global CSS
*/
css: ['element-ui/lib/theme-chalk/index.css'],
}
module.exports = {
/*
** Global CSS
*/
css: ['element-ui/lib/theme-chalk/index.css'],
}删除 'element-ui/lib/theme-chalk/index.css' 作为全局样式的打包配置,改为
module.exports = {
/*
** Global CSS
*/
css: [],
}
module.exports = {
/*
** Global CSS
*/
css: [],
}配置 babel 选项配置 babel 选项配置 babel 选项在 nuxt.config.js 文件中,在选项 build 中配置 babel 选项:
module.exports = {
/*
** Build configuration
** See https://nuxtjs.org/api/configuration-build/
*/
build: {
babel: {

"plugins": [

[

"component",

{

"libraryName": "element-ui",

"styleLibraryName": "theme-chalk"

}

]

]
}
}
}
module.exports = {
/*
** Build configuration
** See https://nuxtjs.org/api/configuration-build/
*/
build: {
babel: {

"plugins": [

[

"component",

{

"libraryName": "element-ui",

"styleLibraryName": "theme-chalk"

}

]

]
}
}
}到此,Element-UI 按需引入配置完成。总结总结总结
