带有 laravel 混合的 vuejs 的大 app.js 文件大小（13 MB）

Question

I am using vuejs with blade file in larvel 5.8. Means i am not using vue router but laravel view. Recently i am facing a big problem that my public/js/app.js file size is about 13 MB,. When i deploye to live, user face slowness when login! I can't even alnalyze as i don't see any config file named webpack.config shown here

My 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));
    }
});

N>B: all my component are injected here (mentioned 2 only for precise)

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

Answer 1

• Note that this is the development build, the production build size would be much smaller and it's what your users would have to download and run

npm run prod

• You can extract vendor assets into a separate file that would be cached longer

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

From the Laravel Mix Docs

• You may also want to installImport Cost extension for Visual Studio Code as it will show you the size of every ES6 module you import or require

And you can instruct Webpack to compile pages specific javascript and vue components so you can include them separately on blade view, see this answer

Please consider this series of articles about Vue.js App Performance Optimization , that really helped me a lot, in understanding lazy-loading, shrinking the size and reducing the load time of my app.
