Mastering Vue.js 3

We, as experienced frontend developers, acknowledge the complexity behind mastering Vue.js 3. This refined guide demystifies this JavaScript framework empowering you to leverage Vue.js 3 for development of scalable, efficient applications.

Deep Dive into Vue.js 3

Before delving further into the Mastering Vue.js 3 journey, it’s crucial to have a solid foundation of this robust JavaScript framework. The introduction of Vue.js 3 has rendered this framework more dynamic, amalgamating new features and upgrades that bolster its performance, security, and usability.

“Vue.js 3”, the recent version of Vue.js that officially debuted in September 2020, stands as a revolutionary JavaScript framework recognized for its simplicity and flexibility.

Advancing to Vue.js 3 Installation

Before one can jump-start on any software or framework, understanding its installation is critical. Let’s navigate through the Vue.js 3 installation process.

Prime your local environment by installing the latest Node.js version. Following this, initiate Vue CLI installation – a standard tool for Vue.js development. Run the command given below:

npm install -g @vue/cli

If you aim to upgrade from Vue.js 2 to Vue.js 3, run the command:

vue upgrade --next

Stitching a Sample Vue.js 3 Application

Armed with a clear understanding of Vue.js 3, let’s proceed to build a rudimentary blog post viewer application. This app will fetch blog posts from an API and present them on a webpage, with detailed views available per post. Through this exercise, we will explore core aspects of Vue.js 3, touching upon the new Composition API, Teleport component, enhanced reactivity system, performance improvements, and TypeScript support.

To fetch and display blog posts, we’ll utilize Vue.js 3’s Composition API and develop a ‘fetchPosts’ method within the setup() function of our ‘PostListComponent’.

import { ref, reactive, toRefs } from "@vue/composition-api";
import axios from "axios";

export default {
  setup() {
    const state = reactive({
      posts: []

    const fetchPosts = async () => {
      const res = await axios.get("https://jsonplaceholder.typicode.com/posts");
      state.posts = res.data;

    return {

When a user wishes to view a specific Blog Post’s details, we can optimize Vue.js 3’s Suspense and Teleport components. The Suspense component handles async operations inside the setup function, while Teleport enables us to render content differently within the DOM.
