How to Make Single Page App Using React and Node.js

Building application Single Page Application (SPA) Use React and Node.js usually requires frontend, backend, API integration and database settings. This can be time consuming, but low-code platforms with AI, accelerate this process by automating generation, deployment and scaling.

This manual passes you by manually creating a MERN-based SPA and how FAB Builder can simplify this process.

What is Single Page Application(SPA)?

A Single Page Application (SPA) loads one HTML page and dynamically updates content using JavaScript instead of re-loading the entire page. This results in faster performance, smoother navigation and more user experience.

Favorite SPAs include Gmail, Facebook, Trello and Google Docs.

Why use React and Node.js for SPA Development?

• React effectively updates the user interface using virtual house, which makes the bath fast and sensitive.
• Node.js with express hands backend API, verification and database operations.
• Both use JavaScript, causing trouble-free development of a full stack.
• SPAS works well with real-time features (eg chat applications, dashboards).

How to Set the MERN stack for a SPA?

Step 1: Create a Backend using Node.js and express

Install addictions and initialize the backend first:

mkdir mern-spa && cd mern-spa
mkdir backend && cd backend
npm init -y
npm install express mongoose cors dotenv nodemon

Create server.js insidebackend/and set the API:

Javascript
const express = require("express");
const mongoose = require("mongoose");
const cors = require("cors");
require("dotenv").config();

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

mongoose
  .connect(process.env.MONGO_URI, { useNewUrlParser: true, useUnifiedTopology: true })
  .then(() => console.log("MongoDB Connected"))
  .catch((err) => console.log(err));

app.get("/", (req, res) => {
  res.send("Welcome to the SPA Backend!");
});

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

Create a file .env:

bash
MONGO_URI=mongodb+srv://your_db_user:[e-mail]/myDatabase

Start the backend:

SH
node server.js

How to Build a Frontend with React?

Go back to the project folder and create React:

SH
npx create-react-app frontend
cd frontend
npm install axios react-router-dom

How to Enable Routing on the Client Side in React?

Edit app.js for use React Router:

Javascript
import React from "react";
import { BrowserRouter as Router, Routes, Route } from "react-router-dom";
import Home from "./pages/Home";
import About from "./pages/About";

function App() {
  return (
    <Router>
      <Routes>
        <Route path="/" element={<Home />} />
        <Route path="/about" element={<About />} />
      </Routes>
    </Router>
  );
}

export default App;

Create Home.js inside pages/:

Javascript
Import React from "React";

Const Home = () => {
  Return  Welcome to Spa's homepage! ;
};

exports of the default house;

Create About.js inside pages/:

Javascript
import React from "react";

const Home = () => {
  return <h1>Welcome to the SPA Home Page!</h1>;
};

export default Home;

Start the frontend:

SH
npm start

How to Connect the React Frontend with Node.js Backend?

Edit API.JS InsideServices/ to process the API requirements:

Javascript
import axios from "axios";

const API_URL = "http://localhost:5000";

export const fetchWelcomeMessage = async () => {
  const response = await axios.get(`${API_URL}/`);
  return response.data;
};

Edit Home.js to view the backend response:

Javascript
import React, { useEffect, useState } from "react";
import { fetchWelcomeMessage } from "../services/api";

const Home = () => {
  const [message, setMessage] = useState("");

  useEffect(() => {
    fetchWelcomeMessage().then((data) => setMessage(data));
  }, []);

  return <h1>{message}</h1>;
};

export default Home;

How to Put on MERN-based SPA?

Option 1: Deploying Backend on render or Heroku

1. Push Backend into GitHub.
2. Deployment on Render or Heroku.

Option 2: Deploying Frontend on Vercel or Netlify

1. Press frontend to GitHub.
2. Deployment on Vercel or Netlify.
