Vue 3 for Beginners

If you’ve already read our Node.js for Beginners guide, you now understand how JavaScript can run outside the browser to power servers, APIs, and backend logic. Node.js is what lets JavaScript handle requests, talk to databases, and return data to users.

But that leads to an important next question:

How do we build the part users actually see and interact with?

That’s where Vue 3 comes in.

In this article, we’ll introduce Vue 3 from a beginner’s perspective and show how it naturally complements Node.js to create modern, interactive web applications.

What Is Vue 3?

Vue 3 is a JavaScript framework for building user interfaces, especially for web pages that update dynamically as data changes.

While Node.js runs on the server, Vue 3 runs in the browser.

Think of it like this:

Node.js → is the engine behind the scenes. It runs on the server, handles data request, powers APIs, and business logic
Vue 3 → Displays that data and responds to user actions. It is the brain of the interface, decides what the user sees and keeps the page in sync when data changes.
Tailwind CSS → is the styling toolkit. It lets you design layouts and components quickly using simple utility classes instead of writing lots of custom CSS.
TypeScript → is the safety net - it adds structure and type checking to JavaScript, helping you catch mistakes early as your app grows.

Together, they form a powerful full‑stack JavaScript setup. Forming a modern JavaScript stack where Node.js provides the data, Vue 3 displays it, Tailwind CSS styles it, and TypeScript keeps everything organized and reliable.

How Vue 3 Fits With Node.js

In our Node.js beginner guide, we talked about creating servers and APIs. Most real applications don’t just return raw text or JSON — they send data to a frontend that users can interact with.

A common flow looks like this:

A user opens a web page in their browser
Vue 3 renders the page
Vue sends a request to a Node.js API
Node.js returns data (for example: products, blog posts, or user info)
Vue automatically updates the page with the new data

This separation keeps your app clean:

Node.js focuses on logic and data
Vue focuses on presentation and interaction

Why Vue 3 Is Beginner‑Friendly

Vue 3 is often recommended for beginners because it balances power and simplicity.

1. It Uses Plain HTML, CSS, and JavaScript

Vue doesn’t replace the basics — it builds on them.

If you already know:

HTML for structure
CSS for styling
JavaScript for logic

…then Vue feels familiar right away.

2. Vue Is Reactive (It Updates Automatically)

One of Vue’s biggest advantages is reactivity.

Instead of manually updating the page when data changes, Vue does it for you.

Example:

A value changes in JavaScript
Vue automatically updates the HTML
No page refresh needed

This makes Vue ideal for dashboards, forms, and dynamic content.

3. Vue Uses Components

Vue apps are built from components — small, reusable pieces of the UI.

Examples of components:

A product card
A navigation bar
A blog post preview
A shopping cart

Each component contains:

HTML (template)
JavaScript (logic)
CSS (styles)

This keeps code organized and easier to maintain.

Check node.js installed

In the PowerShell terminal type:

PS C:\GISE\GIS Engineering\GISE - Documents\ProjectsComputer\vue3\vtson> node -v
v24.13.1

How to Check in VS Code If Vue 3 Is Installed (And Install It If Not)

When people ask “Is Vue 3 installed in VS Code?”, what they usually mean is: Does the project I opened in VS Code already have Vue 3 set up? Vue is typically installed per project (in node_modules), not “inside VS Code.”

1) Open the project folder in VS Code

In VS Code, go to File → Open Folder… and open the folder that contains your project (the one with package.json in the root).

2) Quick check: look for Vue in `package.json`

In the VS Code Explorer, open package.json and look for a dependency like:

"vue": "^3.x.x" (or similar)

If you see vue listed under dependencies, your project is using Vue (likely Vue 3). One of the simplest ways to verify a project’s Vue version is checking package.json.

3) Terminal check (recommended): run `npm list vue`

In VS Code, open the integrated terminal: Terminal → New Terminal

Run:

Shell

npm list vue

This prints the Vue package and version installed in your current project. This is a commonly used way to check the Vue version in a project. [stackoverflow.com]

Tip: Make sure you run the command in the project root (the folder where package.json lives).

If Vue 3 Is NOT Installed: Two Beginner-Friendly Ways to Install It

Option A (Recommended): Create a new Vue 3 project (best for beginners)

Vue’s official quick start recommends scaffolding a new project with:

Shell

npm create vue@latest
Show more lines

This uses the official tool to generate a Vue 3 + Vite project and prompts you for features like TypeScript. [vuejs.org], [npmjs.com]

Steps:

In VS Code Terminal:

Shell

npm create vue@latest
Show more lines

Answer the prompts (you’ll be asked about TypeScript and other options). [vuejs.org]
Then follow the standard start commands:

Shell

cd <your-project-name>

npm install

npm run dev
Show more lines

These are the official “install dependencies and start dev server” steps after scaffolding. [vuejs.org]

Option B: Install Vue into an existing project

If you already have a project folder and just need Vue added, you can install it with npm:

Shell

npm install vue
Show more lines

(After this, you’ll typically configure a build tool like Vite, but for beginners, Option A is usually much simpler and less error‑prone.)

VS Code Setup Tip (Highly Recommended): Install the Vue 3 Extension

To make sure .vue files work nicely in VS Code (syntax highlighting, autocomplete, TypeScript hints), install:

Vue (Official) (formerly “Volar”) from the VS Code Marketplace. [marketplac...studio.com], [vuejs.org]

In VS Code:

Open Extensions (Ctrl/Cmd + Shift + X)
Search “Vue (Official)”
Install it

Vue’s TypeScript guide explicitly recommends VS Code + Vue – Official for the best Vue 3 + TypeScript experience. [vuejs.org]

If you have the older Vue extension “Vetur” installed, Vue’s docs note that Vue – Official replaces it for Vue 3 projects. [vuejs.org]

Troubleshooting (Common Beginner Issues)

npm list vue shows nothing / errors: You may not be in the project root. Open the folder containing package.json and try again. [stackoverflow.com]
npm create vue@latest not working: Make sure Node.js and npm are installed; Vue’s quick start lists Node as a prerequisite. [vuejs.org]
.vue files look like plain text: Install Vue (Official) extension.

A Simple Vue 3 Example

Let’s look at a very basic Vue 3 example that shows how data connects to the page.

<div id="app">
  <h1>{{ message }}</h1>
  <button @click="changeMessage">
    Click Me
  </button>
</div>

<script src="https://unpkg.com/vue@3"></script>
<script>
  const app = Vue.createApp({
    data() {
      return {
        message: "Hello from Vue 3!"
      }
    },
    methods: {
      changeMessage() {
        this.message = "You clicked the button!"
      }
    }
  })

  app.mount("#app")
</script>

What’s happening here?

data() stores the app’s state
{{ message }} displays data in the HTML
Clicking the button updates the data
Vue automatically updates the page

No manual DOM updates required.

Vue 3 vs Traditional JavaScript

Without Vue, you might write code that:

Finds elements manually
Updates text with document.querySelector
Keeps track of state yourself

With Vue:

You describe what the UI should look like
Vue handles how it updates

This declarative approach is one reason frameworks like Vue are so popular for modern web apps.

How Vue 3 and Node.js Work Together (Real‑World Example)

Imagine building a simple blog:

Node.js
- Stores blog posts
- Exposes an API like /api/posts
Vue 3
- Fetches posts from the API
- Displays them on the page
- Updates automatically when new posts are added

Node handles the data, Vue handles the experience.

Why Vue 3 Instead of Other Frameworks?

Vue 3 is often chosen because:

It’s easier to learn than many alternatives
It scales from small projects to large apps
It has excellent performance
It works well with Node.js and modern tooling

For beginners, Vue offers a smoother learning curve without sacrificing capability.

What You Should Learn Next

If you’re following a Node.js → Vue path, a good progression is:

JavaScript fundamentals
Node.js basics (servers, APIs)
Vue 3 basics
- Components
- Reactive data
- Event handling
Connecting Vue to a Node API
Building full applications

This path lets you use JavaScript on both the backend and frontend, making development faster and more consistent.

Final Thoughts
