Scheme

This template is packed with features to support the following:

• Pages Router and App Router
• Static HTML Exports
• API Constructs and Network Requests
• Custom Server configurations
• Authentication and Authorization mechanisms
• Deployment via Docker

File Structures

The basic structure of your project will look like this:

fullstack-nextjs-app-template
├── README.md
├── CHANGELOG.md
├── LICENSE
├── next.config.js
├── server.js
├── ecosystem.config.js
├── middleware.ts
├── tsconfig.json
├── package-lock.json
├── package.json
├── .dockerignore
├── Dockerfile
├── docker-compose.yml
├── out                # Generated HTML/CSS/JS assets
├── server-php.js     # Test server
└── public             # Static resources
```

Getting Started

Before diving in, ensure that Node.js is installed on your computer. Follow the steps below to set everything up:

• Install Dependencies: Run the command npm install to install required libraries.
• Update Next.js: Execute npm i next@latest react@latest react-dom@latest.
• Run Project in Development Mode: Start the server using npm run dev and access it via http://localhost:3000.
• Production Build: Use npm run build to prepare your app for production.

Further Help

When you encounter issues, consider the following troubleshooting methods:

• For instance, if you face the Node.js Port 3000 already in use but it actually isn’t error, run the command killall -9 node.
• To change your site’s favicon, modify the code in pages_document.tsx.
• If you want to customize the menu, simply navigate to src/components/Header and make your modifications.
• Can’t run the application due to installation errors? A common fix is to delete the node_modules folder and reinstall dependencies using npm install.

Understanding the Code Structure

Think of your application as a restaurant. Each component serves a particular dish (functionality), while the underlying file structures provide the kitchen (framework) where the chefs (developers) create their culinary masterpieces (features).

For example:

• Your app folder is akin to the dining area where customers experience the ambiance of your restaurant. This is where user-facing components live.
• The api folder functions as the pantry, stocked with all the ingredients (data) necessary to prepare the dishes (data-fetching tasks).
• The public folder contains static resources, analogous to the menu board visible to customers outside the restaurant.
