by Didin J. on Nov 04, 2025 Build a Realtime Voting App in Vue 3 with Pusher or Socket.IO

Real-time user experiences feel snappy and modern — they keep users engaged by showing live state changes as they happen. In this tutorial, you’ll build a complete Realtime Voting App with a Vue 3 frontend and two interchangeable realtime backends: a self-hosted Socket.IO server (Node + Express) and a managed Pusher integration. By following the hands‑on steps, you’ll learn not only how to wire up real-time events, but also best practices for optimistic UI, simple persistence, and making the app robust enough for production.

by Didin J. on Nov 04, 2025 Build a Realtime Voting App in Vue 3 with Pusher or Socket.IO

Why this tutorial

Practical & deployable: both server implementations are ready to run locally and are easy to deploy. Pick the approach that fits your constraints: Socket.IO if you want control and self‑hosting; Pusher if you prefer a managed service with less operational overhead.

Full stack coverage: we cover backend event design, frontend wiring (socket.io-client and pusher-js), state management with Pinia (or plain composables), optimistic updates, and error handling.

Real-world concerns: the guide includes notes on persistence, scaling (Redis/adapter), authentication, and security patterns such as rate limiting and channel auth for Pusher.

What you’ll learn (learning outcomes)

By the end of this tutorial, you will be able to:

Create a real-time Node server with Socket.IO and a Pusher-backed server.

Integrate real-time events into a Vue 3 + Vite application and update UI in real time.

Implement optimistic voting UX and rollback on failures.

Design simple persistence for polls and scale the real-time layer using Redis adapters or a managed provider.

Secure vote endpoints and protect private/presence channels.

Who this is for

This tutorial is suitable for intermediate JavaScript developers who know basic Vue 3 concepts and Node.js. If you’re new to Vue, you can still follow along — but you may want to skim the Vue 3 + Vite quickstart (links included later) before proceeding.

Time & difficulty

Estimated time to complete: 60–120 minutes to build the demo and run locally (longer if you add persistence or deploy).

Difficulty: Intermediate — you should be comfortable with Node.js, npm, and basic Vue 3 concepts.

What you’ll build

In this tutorial, you’ll create a fully functional Realtime Voting App — a web application where users can view polls, create new ones, and cast votes that update instantly across all connected clients. You’ll learn how the backend and frontend work together to deliver real-time interactivity and smooth user experiences.

Key Features

Live Poll Creation and Updates: Whenever a user creates a new poll, it instantly appears for everyone connected. 1.

Instant Vote Broadcasting: Votes update live across all clients with no need to refresh the page. 1.

Optimistic UI: The vote count increases immediately on the client while awaiting server confirmation for a smooth UX. 1.

Dual Backend Options:

Socket.IO (Self-Hosted): Ideal for developers who want full control and flexibility.

Pusher (Managed): Perfect for those who prefer a plug-and-play, real-time infrastructure. 1.

Simple Persistence: Polls are stored in memory for the demo, but can easily be extended to use databases like MongoDB or Postgres. 1.

Scalable Architecture: Includes notes on scaling with Redis adapters (Socket.IO) or managed channels (Pusher).

Application Flow

Frontend (Vue 3 + Vite): Users can create polls and cast votes through a simple UI built with Vue 3. It subscribes to real-time events using either Socket.IO Client or Pusher JS. 1.

Backend: Handles real-time event broadcasting, poll management, and optional persistence.

For Socket.IO, the server listens for vote events and emits updates to all clients.

For Pusher, the server triggers events through Pusher’s API to broadcast updates. 1.

Realtime Sync: All users connected to the app will see changes reflected instantly.

What You’ll See in Action

A minimalistic dashboard showing a list of active polls.

The ability to create a new poll by entering a question and possible choices.

The ability to vote and see the results update in real time.

A live demo environment that can be deployed easily to Render, Railway, or Netlify.

Preview of the Final App

The final interface will feature:

A poll creation form with dynamic input fields for choices.

A poll list view that shows all current polls.

Vote buttons that instantly update the vote count.

Real-time updates are reflected across multiple open browser tabs.

This small but powerful app demonstrates all the core principles behind building interactive, event-driven applications that stay live and responsive.

Tech Stack & Prerequisites

Before diving into the code, let’s review the tools and technologies you’ll use to build this real-time voting application. Each component of the stack has been carefully chosen for simplicity, modern best practices, and strong community support.

Frontend

Vue 3: The modern version of the Vue framework, featuring the Composition API and reactivity system that make it easy to build fast and dynamic UIs.

Vite: A lightning-fast development server and build tool optimized for Vue 3. It provides instant hot-module replacement and efficient bundling.

Pinia: The official state management library for Vue 3, replacing Vuex with a simpler and more intuitive API.

Axios: For making REST API calls when interacting with the backend (used in the Pusher implementation).

socket.io-client / pusher-js: The real-time client libraries for each respective backend.

UUID: A simple way to generate unique identifiers for polls and choices.

Backend (Option A: Socket.IO)

Node.js + Express: Provides a flexible and fast HTTP + WebSocket server foundation.

Socket.IO: Enables real-time bidirectional communication between clients and the server.

CORS & Body Parser: Middleware for handling cross-origin requests and parsing incoming JSON payloads.

(Optional) Redis: For scaling across multiple server instances and persisting vote counts.

Backend (Option B: Pusher)

Pusher: A managed WebSocket service that abstracts the complexity of scaling and delivering real-time messages. No custom socket server setup is required.

Express: Handles REST API endpoints for creating polls and recording votes.

Pusher Node SDK: For server-side event triggering.

(Optional) Webhooks: Can be used to validate or sync events between Pusher and your backend.

Environment & Tools

Node.js 18+ is installed on your system.

npm, yarn, or pnpm package manager.

A modern browser (Chrome, Firefox, or Edge) for testing.

A code editor such as VS Code with the Vue and ESLint extensions for the best developer experience.

Optional Add-ons

Redis or MongoDB/Postgres: For persistent poll data and horizontal scaling.

Docker: If you want to containerize your backend services.

Ngrok or LocalTunnel: To expose your local backend for remote testing or webhook verification.

Prerequisite Knowledge

You should already have a working understanding of:

JavaScript ES6 syntax (arrow functions, destructuring, modules).

Basic Node.js and Express setup.

Vue 3 fundamentals — components, props, reactivity, and event handling.

If you’re new to any of these, you can still follow along by focusing on one backend implementation first (Socket.IO is recommended for beginners).

Project Structure

To keep this tutorial organized and easy to follow, we’ll separate the backend and frontend into different folders. This allows you to run and deploy them independently while sharing common logic if needed later.

Below is the recommended structure for your project:

realtime-voting/
├── server-socketio/ # Socket.IO-based backend (Node + Express)
│   ├── index.js # Main server entry point
│   ├── package.json # Backend dependencies
│   └── .env.example # Environment variable template (optional)
│
├── server-pusher/ # Pusher-based backend (Node + Express)
│   ├── index.js # Main server entry point for Pusher implementation
│   ├── package.json # Backend dependencies for Pusher
│   └── .env.example # Pusher credentials (App ID, Key, Secret, Cluster)
│
└── client-vue/ # Vue 3 frontend

└── src/
├── main.js # App entry point
├── App.vue # Root component
├── components/ # Vue components (PollList, PollItem, NewPollForm)
├── stores/ # Pinia stores for managing poll state
├── realtime/ # Connection setup for Socket.IO or Pusher
└── assets/ # Optional styling, icons, or images

Directory Breakdown

server-socketio/ — The self-hosted backend option using Socket.IO for real-time communication. This folder includes the Express setup, socket event definitions, and an optional in-memory or persistent store.

server-pusher/ — A managed alternative backend using Pusher. This implementation focuses on broadcasting events to clients through Pusher channels.

client-vue/ — The Vue 3 single-page application (SPA) that interacts with one of the two backends. It manages the UI, state, and real-time connections.

Benefits of This Structure

Modular: You can swap between Socket.IO and Pusher without touching the frontend logic.

Scalable: Each server can evolve independently (e.g., add databases, Docker containers, or new services).

Clean separation of concerns: Frontend and backend remain isolated for easier debugging and deployment.

Development Workflow

Choose one backend to start with (Socket.IO is simpler for local testing). 1.

Run the backend server on port 4000 (Socket.IO) or 5000 (Pusher). 1.

Start the Vue frontend with Vite (default port 5173). 1.

Update the environment variables in client-vue/.env to point to your chosen backend. 1.

Open multiple browser tabs to observe real-time updates when creating polls or voting.

Backend A — Socket.IO (Node + Express)

In this section, you’ll build a simple backend using Node.js, Express, and Socket.IO to handle real-time communication between connected clients. The backend will manage poll creation, vote submission, and broadcasting of updates to all clients instantly.

Step 1: Initialize the Project

Open your terminal and create a new backend folder:

mkdir server-socketio
cd server-socketio
npm init -y

Then install the required dependencies:

npm install express socket.io cors dotenv

Step 2: Create the Server Entry File

Inside the server-socketio folder, create a new file called index.js:

import express from "express";
import { createServer } from "http";
import { Server } from "socket.io";
import cors from "cors";
import dotenv from "dotenv";

dotenv.config();

const app = express();
const httpServer = createServer(app);
const io = new Server(httpServer, {
cors: {
origin: "*", // Allow frontend connections (configure properly in production)
methods: ["GET", "POST"]
}
});

app.use(cors());
app.use(express.json());

// In-memory storage for polls
let polls = [];

// Socket.IO event handlers
io.on("connection", socket => {
console.log("Client connected:", socket.id);

// Send current polls when a client connects
socket.emit("polls", polls);

// Handle new poll creation
socket.on("createPoll", poll => {
const newPoll = {
id: Date.now(),
question: poll.question,
options: poll.options.map(o => ({ text: o, votes: 0 }))
};
polls.push(newPoll);
io.emit("polls", polls); // Broadcast update to all clients
});

// Handle voting
socket.on("vote", ({ pollId, optionIndex }) => {
const poll = polls.find(p => p.id === pollId);
if (poll && poll.options[optionIndex]) {
poll.options[optionIndex].votes += 1;
io.emit("polls", polls); // Broadcast new results
}
});

socket.on("disconnect", () => {
console.log("Client disconnected:", socket.id);
});
});

const PORT = process.env.PORT || 4000;
httpServer.listen(PORT, () => {
console.log(`✅ Socket.IO server running on port ${PORT}`);
});

Step 3: Run the Server

Update the package.json to use module instead of commonjs.

"type": "module",

Start the server by running:

node index.js

You should see:

✅ Socket.IO server running on port 4000

Step 4: Test the Realtime Events (Optional)

You can test the Socket.IO connection using a tool like Socket.IO Tester or by opening multiple browser tabs once the frontend is ready.

Step 5: Environment Variables (Optional)

If you want to configure the port dynamically, create a .env file:

PORT=4000

Then update your script in package.json:

"scripts": {
"test": "echo \"Error: no test specified\" && exit 1",
"start": "node index.js"
},

Run it using:

npm start

With the Socket.IO backend up and running, you now have a real-time server ready to handle voting events. Next, we’ll build Backend B — Pusher (Node + Express) as an alternative managed solution.

Backend B — Pusher (Node + Express)

For those who prefer a managed solution, Pusher provides a simple way to broadcast real-time events without maintaining your own WebSocket server. In this section, we’ll set up a backend that creates polls and broadcasts votes using Pusher channels.

Step 1: Initialize the Project

Create a new backend folder:

mkdir server-pusher
cd server-pusher
npm init -y

Install the required dependencies:

npm install express pusher cors dotenv body-parser

Step 2: Create the Server Entry File

Create index.js in the server-pusher folder:

import express from "express";
import Pusher from "pusher";
import cors from "cors";
import dotenv from "dotenv";
dotenv.config();

const app = express();
app.use(cors());
app.use(express.json());

// Configure Pusher
const pusher = new Pusher({
appId: process.env.PUSHER_APP_ID,
key: process.env.PUSHER_KEY,
secret: process.env.PUSHER_SECRET,
cluster: process.env.PUSHER_CLUSTER,
useTLS: true
});

// In-memory storage for polls
let polls = [];

// Create a new poll
app.post("/polls", async (req, res) => {
const { question, options } = req.body;
const newPoll = {
id: Date.now(),
question,
options: options.map(o => ({ text: o, votes: 0 }))
};
polls.push(newPoll);

try {
await pusher.trigger("polls", "poll-created", newPoll);
res.status(201).json(newPoll);
} catch (err) {
res.status(500).json({ error: String(err) });
}
});

// Vote on a poll
app.post("/polls/:id/vote", async (req, res) => {
const pollId = parseInt(req.params.id);
const { optionIndex } = req.body;
const poll = polls.find(p => p.id === pollId);
if (!poll || !poll.options[optionIndex])
return res.status(400).json({ message: "Invalid poll or option" });

poll.options[optionIndex].votes += 1;

try {
await pusher.trigger("polls", "poll-voted", { pollId, optionIndex, poll });
res.json(poll);
} catch (err) {
res.status(500).json({ error: String(err) });
}
});

// List all polls
app.get("/polls", (req, res) => res.json(polls));

const PORT = process.env.PORT || 5000;
app.listen(PORT, () => console.log(`✅ Pusher server running on port ${PORT}`));

Step 3: Configure Environment Variables

Create a .env file:

PUSHER_APP_ID=your_app_id
PUSHER_KEY=your_key
PUSHER_SECRET=your_secret
PUSHER_CLUSTER=your_cluster
PORT=5000

Replace placeholders with your Pusher credentials from your Pusher dashboard.

Step 4: Run the Server

Update the package.json to use module instead of commonjs.

"type": "module",

Start the backend:

node index.js

You should see:

✅ Pusher server running on port 5000

Step 5: Notes on Security & Presence Channels

For production, secure Pusher private or presence channels with server-side authentication.

Implement rate limiting to prevent vote spamming.

You can use webhooks to validate events or sync votes to a database.

With the Pusher backend ready, you can now move to building the Vue 3 frontend that connects to either Socket.IO or Pusher to provide a live voting experience.

Frontend — Vue 3 App

In this section, we’ll build the Vue 3 frontend using Vite. The app will connect to either the Socket.IO or Pusher backend to provide real-time poll updates and voting.

Step 1: Set up the Project

Create the Vue project using Vite:

npm create vite@latest client-vue -- --template vue
cd client-vue
npm install

Install additional dependencies:

npm install socket.io-client pusher-js axios pinia uuid

Step 2: Project Layout

client-vue/
├── index.html
├── package.json
├── vite.config.js
└── src/
├── main.js # App entry
├── App.vue # Root component
├── components/ # PollList.vue, PollItem.vue, NewPollForm.vue
├── stores/ # Pinia store
└── realtime/ # socket.js, pusher.js

Step 3: Set up Realtime Connections

Socket.IO client:

import { io } from 'socket.io-client';

const SOCKET_URL = import.meta.env.VITE_SOCKET_URL || 'http://localhost:4000';

export const socket = io(SOCKET_URL);

Pusher client:

import Pusher from 'pusher-js';

const KEY = import.meta.env.VITE_PUSHER_KEY;
const CLUSTER = import.meta.env.VITE_PUSHER_CLUSTER;

export function createPusher() {
return new Pusher(KEY, { cluster: CLUSTER });
}

Step 4: Create Pinia Store

src/stores/polls.js

import { defineStore } from "pinia";
import { ref } from "vue";

export const usePollStore = defineStore("polls", () => {
const polls = ref([]);

function setPolls(list) {
polls.value = list;
}
function addOrReplacePoll(poll) {
const idx = polls.value.findIndex(x => x.id === poll.id);
if (idx === -1) polls.value.push(poll);
else polls.value[idx] = poll;
}

return { polls, setPolls, addOrReplacePoll };
});

Step 5: Connect Socket.IO in Components

src/components/PollList.vue (simplified)

<template>
<div>
<h1>Polls</h1>
<PollItem v-for="poll in polls" :key="poll.id" :poll="poll" />
</div>
</template>


<script setup>
import { onMounted, onBeforeUnmount } from 'vue';
import { usePollStore } from '../stores/polls';
import { socket } from '../realtime/socket';

const store = usePollStore();

onMounted(() => {
socket.on('polls', (list) => store.setPolls(list));
});

onBeforeUnmount(() => {
socket.off('polls');
});
</script>

Step 6: Connect Pusher in Components

import { createPusher } from '../realtime/pusher';

const store = usePollStore();
const pusher = createPusher();
const channel = pusher.subscribe('polls');

channel.bind('poll-created', (poll) => store.addOrReplacePoll(poll));
channel.bind('poll-voted', ({ poll }) => store.addOrReplacePoll(poll));

Step 7: Optimistic Voting

When a user votes, immediately increment the vote count locally for a snappy UX, then send the event to the backend. Roll back if the server returns an error:

async function vote(pollId, optionIndex) {
const poll = store.polls.find(p => p.id === pollId);
const choice = poll.options[optionIndex];
choice.votes += 1; // optimistic

try {
// Socket.IO
socket.emit('vote', { pollId, optionIndex });
// Or Pusher via HTTP POST
// await axios.post(`${API}/polls/${pollId}/vote`, { optionIndex });
} catch (err) {
choice.votes -= 1; // rollback
alert('Vote failed: ' + (err?.message || 'unknown'));
}
}

Authentication & Security Notes

Although this tutorial focuses on real-time features, it’s important to consider authentication and security before deploying your voting app to production. Here are the best practices to keep your app safe and reliable.

1. Backend Authentication

JWT Tokens: Use JSON Web Tokens (JWT) to authenticate users and protect API endpoints.

Middleware: In Express, create middleware to verify JWTs for creating polls, voting, or accessing private channels.

Role-based Access: Optionally implement roles (admin, user) to control who can create polls or view sensitive data.

2. Socket.IO Security

Authorization Middleware: Authenticate sockets during connection:

io.use((socket, next) => {
const token = socket.handshake.auth.token;
if (isValidToken(token)) next();
else next(new Error('Unauthorized'));
});

Rate Limiting: Prevent abuse by limiting the number of votes per user per time window.

Input Validation: Always validate poll questions and choices to prevent injection attacks.

3. Pusher Security

Private/Presence Channels: Use Pusher private or presence channels to ensure only authenticated users can join.

Server-side Authentication: Implement an auth endpoint on your backend to provide temporary credentials to the client.

Webhook Verification: If using Pusher webhooks, verify requests using HMAC signatures.

4. General Security Practices

CORS Configuration: Restrict allowed origins to your frontend URLs.

HTTPS: Always use HTTPS for production deployments to encrypt traffic.

Environment Variables: Store sensitive keys (Pusher credentials, JWT secrets) in environment variables, never in source code.

Logging & Monitoring: Track suspicious activity, vote spikes, and failed authentication attempts.

5. Optional Enhancements

Database Persistence: Move from in-memory storage to a database to prevent data loss.

Vote Throttling: Limit users to one vote per poll or per IP address.

Captcha Verification: Use Google reCAPTCHA to prevent automated spam voting.

Frontend UI — Poll Components & Styling

A polished and intuitive UI improves the user experience. In this section, we’ll build the key Vue components for your Realtime Voting App and apply minimal styling for clarity.

Step 1: Create Components Directory

mkdir src/components

Step 2: PollList Component

src/components/PollList.vue

<template>
<div class="poll-list">
<NewPollForm />
<PollItem v-for="poll in polls" :key="poll.id" :poll="poll" />
</div>
</template>


<script setup>
import { usePollStore } from '../stores/polls';
import { computed } from 'vue';
import PollItem from './PollItem.vue';
import NewPollForm from './NewPollForm.vue';

const store = usePollStore();
const polls = computed(() => store.polls);
</script>


<style scoped>
.poll-list {
max-width: 600px;
margin: 0 auto;
padding: 1rem;
}
</style>

Step 3: PollItem Component

src/components/PollItem.vue

<template>
<div class="poll-item">
<h3>{{ poll.question }}</h3>
<ul>
<li v-for="(option, index) in poll.options" :key="index">
<button @click="vote(index)">{{ option.text }} ({{ option.votes }})</button>
</li>
</ul>
</div>
</template>


<script setup>
import { usePollStore } from '../stores/polls';
import { socket } from '../realtime/socket';

const props = defineProps({ poll: Object });
const store = usePollStore();

function vote(optionIndex) {
// Optimistic update
props.poll.options[optionIndex].votes += 1;
socket.emit('vote', { pollId: props.poll.id, optionIndex });
}
</script>


<style scoped>
.poll-item {
border: 1px solid #ccc;
padding: 0.5rem;
margin-bottom: 1rem;
border-radius: 8px;
}
button {
margin: 0.25rem;
padding: 0.25rem 0.5rem;
cursor: pointer;
}
</style>

Step 4: NewPollForm Component

src/components/NewPollForm.vue

<template>
<form @submit.prevent="submitPoll" class="new-poll-form">
<input v-model="question" placeholder="Poll question" required />
<div v-for="(option, index) in options" :key="index">
<input v-model="options[index]" placeholder="Option" required />
</div>
<button type="button" @click="addOption">Add Option</button>
<button type="submit">Create Poll</button>
</form>
</template>

<script setup>
import { ref } from 'vue';
import { socket } from '../realtime/socket';

const question = ref('');
const options = ref(['', '']);

function addOption() {
options.value.push('');
}

function submitPoll() {
if (question.value.trim() && options.value.every(o => o.trim())) {
socket.emit('createPoll', { question: question.value, options: options.value });
question.value = '';
options.value = ['', ''];
} else {
alert('Please fill in all fields');
}
}
</script>


<style scoped>
.new-poll-form {
display: flex;
flex-direction: column;
gap: 0.5rem;
margin-bottom: 2rem;
}
input {
padding: 0.25rem;
border-radius: 4px;
border: 1px solid #ccc;
}
button {
padding: 0.25rem 0.5rem;
cursor: pointer;
}
</style>

Step 5: Styling Tips

Keep a consistent padding and margin scheme for readability.

Use subtle borders and border-radius for a modern look.

Highlight active votes or recently updated polls with a background animation (optional).

Testing and Benchmarking

Ensuring your Realtime Voting App works reliably is essential. In this section, we’ll cover basic testing strategies and performance considerations.

1. Manual Testing

Multiple Tabs: Open several browser tabs to simulate multiple users voting simultaneously.

Poll Creation: Verify that creating a poll updates all connected clients immediately.

Voting: Check that votes increment in real-time across all clients.

Rollback: Test that optimistic UI updates rollback correctly if the server fails to process a vote.

2. Automated Testing (Optional)

Backend API Testing:

Use tools like Postman or Insomnia to test REST endpoints for the Pusher backend.

Example: Send POST requests to `/polls` and `/polls/:id/vote` and validate responses.

Socket.IO Testing:

Use socket.io-client in Node tests to simulate multiple connections.

Example: Connect multiple clients, emit votes, and verify that polls events are received.

import { io } from 'socket.io-client';
const client = io('http://localhost:4000');
client.on('connect', () => console.log('Connected'));
client.on('polls', data => console.log('Polls update:', data));

3. Load Testing

Tools: Use Artillery or k6 to simulate multiple concurrent connections and vote events.

Metrics: Monitor response time for creating polls and broadcasting votes.

Scalability: For Socket.IO, consider the Redis Adapter if you plan to scale across multiple server instances.

4. Frontend Testing

Unit Tests: Test Vue components with Vue Test Utils and Jest.

State Updates: Ensure Pinia store updates correctly on socket or Pusher events.

User Interactions: Test that button clicks trigger vote events and update UI correctly.

5. Error Handling

Network Failures: Simulate server disconnects and ensure the frontend handles reconnection.

Invalid Inputs: Test creating polls with empty questions or options.

Server Errors: Ensure optimistic UI rolls back votes if the server rejects them.

6. Continuous Integration (CI)

Integrate automated tests into a CI pipeline (GitHub Actions, GitLab CI, or CircleCI).

Run backend API tests and frontend component tests on each push or pull request.
