Vue.js 3 Cookbook

By: Heitor Ramon Ribeiro

Overview of this book

Vue.js is a progressive web framework for building professional user interfaces for your web applications. With Vue.js 3, the frontend framework is reinforced with architectural enhancements, new base languages, new render processes, and separated core components. The book starts with recipes for implementing Vue.js 3’s new features in your web development projects and migrating your existing Vue.js apps to the latest version. You will get up and running with TypeScript with Vue.js and find succinct solutions to common challenges and pitfalls faced in implementing components, derivatives, and animation, through to building plugins, adding state management, routing, and developing complete single-page applications (SPAs). As you advance, you'll discover recipes to help you integrate Vue.js apps with Nuxt.js in order to add server-side rendering capabilities to your SPAs. You'll then learn about the Vue.js ecosystem by exploring modern frameworks such as Quasar, Nuxt.js, Vuex, and Vuetify in your web projects. Finally, the book provides you with solutions for packaging and deploying your Vue.js apps. By the end of this Vue.js book, you'll be able to identify and solve challenges faced in building Vue.js applications and be able to adopt the Vue.js framework for frontend web projects of any scale.

How to do it...

First, we need to create our Vue CLI project. We can use the one we created in the last recipe or start a new one. To find how to create a Vue CLI project with TypeScript, please check the 'Adding TypeScript to a Vue CLI project' recipe.

Now, follow these steps to add custom hooks to your Vue project using TypeScript and vue-class-component:

  1. We need to add vue-router to the project. This can be done with the Vue CLI project creation or in the Vue UI interface after the project has been created.
If prompted about the mode, the vue-router should run. Take note that selecting the History option will require special server configuration when it's time to deploy.
  1. Open Terminal (macOS or Linux) or Command Prompt/PowerShell (Windows) and execute the npm run serve command, and you will see that the vue-router is working and that there are two working routers: home and about.
  1. Let's start creating and naming our hooks to register on the main application. To do this, we need to create a vue-router.js file inside the src/classComponentsHooks folder:
import Component from 'vue-class-component';

  1. We need to import this file to the main.ts file as it needs to be called before the application final build:
import './classComponentsHooks/vue-router';

import Vue from 'vue';
import App from './App.vue';
import router from './router';

Vue.config.productionTip = false;

new Vue({
render: h => h(App),
  1. We now have the hooks registered on the vue-class-component and they can be used inside the TypeScript components.
  1. We need to create a new router location called Secure.vue in the src/views folder. The secure page will have a password to enter, vuejs. When the user enters this password, the router guard will grant permission, and the user can see the page. If the password is wrong, the user will be taken back to the home page. When they leave the page, an alert will show a message to the user:
<div class="secure">
<h1>This is an secure page</h1>

<script lang="ts">
import { Component, Vue } from 'vue-property-decorator';
import { Route, RawLocation } from 'vue-router';

type RouteNext = (to?: RawLocation | false | ((vm: Vue) => any) |
void) => void;

export default class Home extends Vue {
beforeRouteEnter(to: Route, from: Route, next: RouteNext) {
const securePassword = 'vuejs';

const userPassword = prompt('What is the password?');

if (userPassword === securePassword) {
} else if (!userPassword) {

beforeRouteLeave(to: Route, from: Route, next: RouteNext) {
  1. Now with our page done, we need to add it to the router.ts file to be able to call it in the Vue application:
import Vue from 'vue';
import Router from 'vue-router';
import Home from './views/Home.vue';


export default new Router({
routes: [
path: '/',
name: 'home',
component: Home,
path: '/about',
name: 'about',
component: () => import('./views/About.vue'),
path: '/secure',
name: 'secure',
component: () => import('./views/Secure.vue'),
  1. With the route added and the view created, the final step is to add the link to the main App.vue file, and we will have a component with an integrated hook on it:
<div id="app">
<div id="nav">
<router-link to="/">Home</router-link> |
<router-link to="/about">About</router-link> |
<router-link to="/secure">Secure</router-link>
