带有laravel混合的vuejs的大app.js文件大小（13 MB）

Question

我在larvel 5.8中将vuejs与刀片文件一起使用。意味着我没有使用vue路由器，而是laravel视图。最近我面临一个大问题，我的public / js / app.js文件大小约为13 MB！当我部署到生活中时，用户登录时会变慢！我什至无法分析，因为我看不到任何名为webpack.config shown here

的配置文件

我的app.js：

        import Vue from "vue"; 
    window.Vue = Vue;
    window.axios = require("axios");
    window.axios.defaults.headers.common["X-Requested-With"] = "XMLHttpRequest";
    require("promise.prototype.finally").shim();

    import { Form, HasError, AlertError } from "vform";
    window.Form = Form;

    Vue.component(HasError.name, HasError);
    Vue.component(AlertError.name, AlertError);

    Vue.component("pagination", require("laravel-vue-pagination"));

    //sweet alert 2

    import swal from "sweetalert2";
    window.swal = swal;
    const toast = swal.mixin({
        toast: true,
        position: "top-end",
        showConfirmButton: false,
        timer: 15000
    });
    window.toast = toast;

    //vue lang

    import VueInternationalization from "vue-i18n";
    import Locale from "./vue-i18n-locales.generated";

    Vue.use(VueInternationalization);

    const lang = document.documentElement.lang.substr(0, 2);
    // or however you determine your current app locale

    const i18n = new VueInternationalization({
        locale: lang,
        messages: Locale
    });

    //vue lang end

    //https://hamed-ehtesham.github.io/pretty-checkbox-vue/#installation

    import PrettyCheckbox from "pretty-checkbox-vue";
    Vue.use(PrettyCheckbox);

    //vue autocomplete

    //ckeditor

    import CKEditor from "@ckeditor/ckeditor5-vue";
    Vue.use(CKEditor);

    /**
     * Next, we will create a fresh Vue ap
     *
     *
     * plication instance and attach it to
     * the page. Then, you may begin adding components to this application
     * or customize the JavaScript scaffolding to fit your unique needs.
     */

    // dash board

    Vue.component(
        "dashboard-site-employee-attendance-list",
        require("./components/dashboard/site/employeeAttendanceListComponent.vue")
    );
    Vue.component(
        "employee-attendance-master-component",
        require("./components/dashboard/site/latestAttendanceListComponent.vue")
    );
Vue.filter("round", function(value) {
    return parseFloat(value).toFixed(0);
});

const app = new Vue({
    el: "#app",
    i18n,
    components: {},

    methods: {},
    mounted() {
        console.log("d" + document.documentElement.lang.substr(0, 2));
    }
});

Webpack.mix.js

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css');

我的package.json文件

EDit

Answer 1

• 请注意，这是开发版本，生产版本的大小要小得多，这是用户必须下载并运行的版本

npm run prod

• 您可以将供应商资产提取到一个单独的文件中，该文件将被缓存更长的时间

mix.js('resources/js/app.js', 'public/js')
   .sass('resources/sass/app.scss', 'public/css')
   .extract();

从Laravel Mix Docs开始

• 您可能还想为Visual Studio Code安装Import Cost扩展名，因为它将显示您导入或需要的每个ES6模块的大小

并且您可以指示Webpack编译页面特定的javascript和vue组件，以便可以将它们分别包含在刀片视图中，请参见this answer

Answer 2

请考虑有关Vue.js应用程序性能优化的系列文章，这对理解延迟加载，缩小大小和减少应用程序的加载时间确实有很大帮助。

1. Lazy loading and code splitting in Vue.js
2. Vue.js Router Performance
3. Lazy Loading Individual Vue Components and Prefetching

主要内容：

• 性能优化和延迟加载简介。
• 延迟加载路线和供应商捆绑包反模式。
• 延迟加载Vuex模块
• 提供良好的等待体验并延迟加载单个组件
• 延迟加载库并找到较小的等效项
• UI库的性能友好用法
• 使用Service Worker缓存
• 预取
