The Ultimate Guide to Building an Efficient Monolith Starter Project Structure for Express.js REST API and Next.js SSR Client

Introduction

Are you tired of juggling multiple projects and struggling to maintain a cohesive codebase for your Express.js REST API and Next.js SSR client? Look no further! In this comprehensive guide, we’ll walk you through the most efficient monolith starter project structure that allows you to seamlessly integrate both technologies and create a robust, scalable, and maintainable application.

Why a Monolith Starter Project?

A monolith starter project is an excellent way to kick-start your development journey, especially when working with multiple technologies like Express.js and Next.js. By having a single project structure, you can:

• Simplify project management and maintenance
• Reduce overhead and improve development speed
• Enhance collaboration and teamwork
• Streamline deployment and testing processes

Project Structure Overview

Before we dive into the nitty-gritty, let’s take a high-level look at the project structure we’ll be creating:

PROJECT_ROOT
app
express
api
routes
controllers
models
utils
next
client
components
pages
public
styles
utils
package.json

Step 1: Setting Up the Project

Let’s start by creating a new project folder and initializing a new Node.js project using npm:

mkdir monolith-starter
cd monolith-starter
npm init -y

Step 2: Installing Dependencies

Install the required dependencies for Express.js and Next.js:

npm install express next react react-dom

Step 3: Creating the Express.js REST API

Create a new folder for the Express.js API and add the following files:

app/express/api/
index.js
routes/
user.js
product.js
...
controllers/
user.js
product.js
...
models/
user.js
product.js
...
utils/
logger.js

Index.js (API Entry Point)

const express = require('express');
const app = express();
const routes = require('./routes');

app.use(express.json());
app.use('/api', routes);

const PORT = 3000;
app.listen(PORT, () => console.log(`API listening on port ${PORT}`));

Routes

Create separate files for each route, e.g., user.js and product.js:

// user.js
const express = require('express');
const router = express.Router();

router.get('/', async (req, res) => {
  // logic for retrieving users
});

router.post('/', async (req, res) => {
  // logic for creating a new user
});

module.exports = router;

Step 4: Creating the Next.js SSR Client

Create a new folder for the Next.js client and add the following files:

app/next/
client/
components/
Header.js
Footer.js
...
pages/
index.js
about.js
...
public/
images/
styles/
globals.css
components/
header.css
...
utils/
logger.js

next.config.js

Create a next.config.js file to configure Next.js:

module.exports = {
  target: 'serverless',
};

pages/_app.js

Create a _app.js file to setup the client-side app:

import App from 'next/app';
import Head from 'next/head';
import {AuthProvider} from '../context/AuthContext';

function MyApp({ Component, pageProps }) {
  return (
    
      
        
      
      
    
  );
}

export default App(MyApp);

Step 5: Integrating Express.js and Next.js

Create a new file, server.js, at the project root to integrate Express.js and Next.js:

const express = require('express');
const next = require('next');
const app = next();
const expressApp = express();

app.prepare().then(() => {
  expressApp.use('/api', require('./app/express/api'));
  expressApp.use((req, res) => {
    return app.render(req, res);
  });

  const PORT = 3000;
  expressApp.listen(PORT, () => console.log(`Server listening on port ${PORT}`));
});

Step 6: Running the Application

Finally, update the scripts section in package.json to run the application:

"scripts": {
  "dev": "node server.js"
}

Run the application using:

npm run dev

Conclusion

Congratulations! You now have a fully functional monolith starter project structure that combines the power of Express.js and Next.js. This setup provides a solid foundation for building robust, scalable, and maintainable applications. Remember to keep your project organized, follow best practices, and continuously refactor and improve your codebase.

Bonus: Tips and Best Practices

Here are some additional tips and best practices to keep in mind:

1. Keep your project organized: Use a clear and consistent folder structure, and keep related files and components together.
2. Separate concerns: Keep your Express.js API and Next.js client separate, and avoid mixing responsibilities.
3. Use environment variables: Use environment variables to configure your application, and avoid hardcoding values.
4. Implement authentication and authorization: Use a robust authentication and authorization system to secure your API and client.
5. Monitor and log errors: Use a logging library and monitoring tools to track errors and performance issues.
6. Test and deploy regularly: Regularly test and deploy your application to catch issues early and ensure smooth operations.

Folder/File	Description
app/express/api	Express.js API folder
app/next/client	Next.js client folder
server.js	Integration file for Express.js and Next.js
package.json	Project configuration file
