Vue.js PWA/SPA template configured for SEO


Vue.js PWA/SPA template configured for SEO (initially scaffolded with vue-cli). You can find the React version here: react-seo-friendly-spa-template.




General Overview

This template reflects some of the setup I went through when experimenting with the creation of my own static front-end personal site that was to be hosted on Netlify (using GitHub as a repository/pipeline). You can find that experiment live here. After playing around with this process I figured I’d build a higher-level abstraction of that project for quick re-use in the future.

Technology Stack Overview


initial scaffolding


vue-meta - plugin that allows you to manage your app’s meta information, much like react-helmet does for React. However, instead of setting your data as props passed to a proprietary component, you simply export it as part of your component’s data using the metaInfo property.

I have it configured to use a readonly objects of type MetaInfo (defined in @/config/metaInfo.config.ts) - in the component options of the component, you must declare the metaInfo prop, which takes the object as its value:


import { MetaInfo } from 'vue-meta';

export const MetaInfoAbout = Object.freeze<MetaInfo>({
  title: 'About',
  titleTemplate: '%s | VueSeoFriendlySpaTemplate',
  meta: [
      property: 'og:title',
      content: 'About',
      vmid: 'og:title',
      property: 'og:description',
      content: 'About page description - limit of 160 characters (try for 150-155).',
      vmid: 'og:description',
      name: 'description',
      content: 'About page description - limit of 160 characters (try for 150-155).',


<script lang="ts">
import { Component, Vue } from "vue-property-decorator";
import { MetaInfoAbout } from "@/config/metaInfo.config";

  metaInfo: MetaInfoAbout
export default class About extends Vue {}


vue-analytics - Google Analytics manager plugin. The plugin isn’t just a wrapper of the Google Analytics API, but provides a solution to issues that most of the time you don’t want to deal with or you not even know you have to deal with.

My preferred configuration:

  • id: replace with your GA tracking code
  • checkDuplicatedScript: checks if the GA script has already been added/loaded before injecting - this is especially useful when you are using prerendering or SSR. You wont need to worry about removing a duplicate script tag or delaying the injection.
  • router (pass the vue-router object and the plugin will handle route tracking/collection automatically).
  • debug/sendHitTask: this controls when to actually fire GA collection requests - I configure it to only fire in production builds.


import Vue from 'vue';
import router from '@/router';
import VueAnalytics from 'vue-analytics';

const isProd = (process.env.NODE_ENV === 'production');

Vue.use(VueAnalytics, {
  id: 'UA-xxxxxxxxx-x',
  checkDuplicatedScript: true,
  debug: {
    enabled: !isProd,
    sendHitTask: isProd,


prerender-spa-plugin - Prerenders static HTML in a single-page application. This is a more straightforward substitue for SSR (Server Side Rendering) and the primary benefit is SEO.

Configured in the app as follows:

main.ts - need to fire an event after the app is mounted to let the prerenderer know when to pick up from. vue.config.js - add the renderAfterDocument property to the renderer (value matching the event name dispatched in main.ts).

Note: renderAfterDocument is only needed if you need to await the result of an async request and/or any of the prerendered markup relies on javascript. In the default state of this app, it is not needed, but I left it in just in case as the impact to load time is minimal. I also found in more complex applications that the mounted() callback fires prematurely before some of the more deeply nested child components finish rendering - making use of $nextTick here solves this issue.


import Vue from "vue";
import App from "@/App.vue";
import router from "@/router";

const prerenderEventName = 'prerender-event';

// In the mounted callback dispatch the event telling prerendered app when to pick up from.
// Wrap in this.$nextTick callback to ensure all components/child components have finished mounting/rendering.
new Vue({
  render: (h) => h(App),
  mounted: function () {
    this.$nextTick(function () {
      document.dispatchEvent(new Event(prerenderEventName));


const path = require("path");
const cheerio = require("cheerio");
const PrerenderSPAPlugin = require("prerender-spa-plugin");

module.exports = {
  configureWebpack: (config) => {
    if (process.env.NODE_ENV !== "production") {
      return {};

    return {
      plugins: [
        new PrerenderSPAPlugin({
          staticDir: config.output.path,
          routes: ["/", "/about", "/404"],
          renderAfterDocumentEvent: 'prerender-event',
          renderer: new PrerenderSPAPlugin.PuppeteerRenderer({}),
          postProcess(context) {
            if (context.route === "/404") {
              context.outputPath = path.join(config.output.path, "/404.html");

            // Remove google analytics script (will be readded by client)
            // Add data-server-rendered="true" to #app (dynamically add here rather than hard code in index.html)
            const $ = cheerio.load(context.html);
            $('#app').attr('data-server-rendered', 'true');
            context.html = $.html();

            return context;

Remainder of the configuration takes place in vue.config.js file where the plugin is added and configured. In the postProcess callback I am editing the prerendered content using cheerio so you can load the raw prerendered html string into a usable document and modify it using JQuery-like syntax, rather than parsing a long string and calling .replace.

Note: I found that dynamically adding the data-server-rendered='true' attribute in the postProcess (rather than hard-coding in the index.html file) seems to work well - this lets the client know that this nodes contents was served as prerendered content and to hydrate the HTML with updates, rather than re-render/replace.


npm install

After cloning the repo, run this command. This will:

  • Install Node dependencies from package.json

npm run serve

To start the app (development build), run this command. This will:

  • Compile the app and run on the development server

npm run lint

  • Run the linter (configured in the tslint.json file found in the root of this project)

npm run sitemap

  • This command will execute code in the sitemap-generator.js. Using the sitemapUrl parameter defined in that file (should reflect your registered domain name) a sitemap.xml is generated and persisted under the ‘public’ folder - this file is referenced in the robots.txt file. This uses the sitemap-generator package.

npm run build

This script will:

  • Build release Webpack bundles
