vue服務端渲染——Nuxt.js全面配置

Nuxt.js 全面配置(持續更新中)

其餘系列

★ vue-cli3 全面配置

☞ 初始化項目

npx create-nuxt-app <項目名>
或
npx create-nuxt-app <項目名>

☞ 環境變量配置

  能夠配置在客戶端和服務端共享的環境變量

module.exports = {
  env: {
    baseUrl: process.env.BASE_URL || 'http://localhost:3000'
  }
}

  經過如下兩種方式來使用 baseUrl 變量

1. 經過 process.env.baseUrl
2. 經過 context.baseUrl，請參考context api

☞ 打包分析

  package.json 中添加 analyze 命令

"analyze": "nuxt build --analyze"

  修改 nuxt.config.js

export default {
  build: {
    analyza: {
      analyzeMode: 'static'
    }
  }
}

☞ 提供全局 scss 變量

• 方法一：

npm i -S @nuxtjs/style-resources
npm i -D sass-loader node-sass

  修改 nuxt.config.js

export default {
  modules: [
    '@nuxtjs/style-resources',
  ],
  styleResources: {
    scss: '~/assets/scss/variable.scss'
  }
}

• 方法二：

npm i -D nuxt-sass-resources-loader sass-loader node-sass

  修改 nuxt.config.js

export default {
  modules: [
    ['nuxt-sass-resources-loader', ['~/assets/scss/variable.scss']]
  ],
  styleResources: {
    scss: '~/assets/scss/variable.scss'
  }
}

☞ 按需引入 element-ui

npm i -D babel-plugin-component
// or
yarn add -D babel-plugin-component

  修改 nuxt.config.js

module.exports = {
  plugins: ['@/plugins/element-ui'],
  build: {
    babel: {
      plugins: [
        [
          'component',
          { libraryName: 'element-ui', styleLibraryName: 'theme-chalk' }
        ]
      ]
    }
  },
}

  修改 plugins/element-ui.js

import Vue from 'vue'
import {
  Button, Loading, Notification, Message, MessageBox
} from 'element-ui'

import lang from 'element-ui/lib/locale/lang/zh-CN'
import locale from 'element-ui/lib/locale'

// configure language
locale.use(lang)

// set
Vue.use(Loading.directive)
Vue.prototype.$loading = Loading.service
Vue.prototype.$msgbox = MessageBox
Vue.prototype.$alert = MessageBox.alert
Vue.prototype.$confirm = MessageBox.confirm
Vue.prototype.$prompt = MessageBox.prompt
Vue.prototype.$notify = Notification
Vue.prototype.$message = Message

// import components
Vue.use(Button);
// or
// Vue.component(Button.name, Button)

☞ 配置 hard-source-webpack-plugin

npm i -D hard-source-webpack-plugin

  修改 nuxt.config.js

module.exports = {
  build: {
    extractCSS: true,
    extend(config, ctx) {
      if (ctx.isDev) {
        config.plugins.push(
          new HardSourceWebpackPlugin({
            cacheDirectory: '.cache/hard-source/[confighash]'
          })
        )
      }
    }
  }
}

☞ 去除多餘 css

npm i --D glob-all purgecss-webpack-plugin

  若安裝失敗,請先用管理員身份安裝如下全局依賴

npm install --global windows-build-tools
或
yarn global add windows-build-tools

  修改 nuxt.config.js

const PurgecssPlugin = require('purgecss-webpack-plugin')
const glob = require('glob-all')
const path = require('path')
const resolve = dir => path.resolve(__dirname, dir);

module.exports = {
  build: {
    extractCSS: true,
    extend(config, ctx) {
      if (!ctx.isDev) {
        config.plugins.push(
          new PurgecssPlugin({
            paths: glob.sync([
              resolve('./pages/**/*.vue'),
              resolve('./layouts/**/*.vue'),
              resolve('./components/**/*.vue')
            ]),
            extractors: [
              {
               extractor: class Extractor {
                  static extract(content) {
                    const validSection = content.replace(
                      /<style([\s\S]*?)<\/style>+/gim,
                      ""
                    );
                    return validSection.match(/[A-Za-z0-9-_:/]+/g) || [];
                  }
                },
                extensions: ['vue']
              }
            ],
            whitelist: ['html', 'body', 'nuxt-progress']
          })
        )
      }
    }
  }
}

☞ Brotli 壓縮

npm i shrink-ray-current

  若安裝失敗,請先用管理員身份安裝如下全局依賴

npm install --global windows-build-tools
或
yarn global add windows-build-tools

  修改 nuxt.config.js

export default {
  render: {
    http2: {
      push: true
    },
