Getting Started

Prerequisites

Make sure you have the following installed on your machine:

  • Node.js (v14 or later)
  • npm (or yarn)

Installation

  1. Clone the repository:

    git clone https://github.com/your-username/your-repo.git

  2. Navigate to the project directory:

    cd your-repo

  3. Install the dependencies:

    npm install

  4. Copy the .env.template:

    cp .env.template .env

  5. Start the development server:

    npm run dev

The application should now be running at http://localhost:3000.

Folder Structure

This project follows a modular file structure based on Next.js v14's src/app directory layout. Here's an overview:

src/
├── app/
│   ├── some-page/
│   │   ├── page.tsx       # Corresponds to the URL /some-page
│   │   └── __tests__/
│   │       └── some-page.test.tsx
│   ├── layout.tsx         # Main layout for the application
│   ├── theme.ts           # Material UI theme configuration
│   └── page.tsx           # Homepage (URL: /)
│
├── Components/
│   ├── __tests__/
│   │   └── Header.test.tsx # Unit tests for the Header component
│   └── Header.tsx          # Header component
│
└── store/
    └── useStore.ts         # Zustand store for state management

Running the Project

To start the development server:

npm run dev

This will launch the application at http://localhost:3000.

To build the application for production:

npm run build

To start the production build:

npm run start

Testing

We use Jest and React Testing Library to test components and application logic.

Running Tests

To run all tests:

npm run test

Tests are located in the __tests__ directories adjacent to the components or pages they test.

Theming

This project uses Material UI for theming. The theme is configured in the src/app/theme.ts file.

To apply the theme globally in your application, you can use the ThemeProvider component provided by Material UI in your src/app/layout.tsx file.

Applying the Theme

In your layout.tsx:

// src/app/layout.tsx
import { ThemeProvider } from '@mui/material/styles';
import CssBaseline from '@mui/material/CssBaseline';
import theme from './theme'; // Import your custom theme

export default function Layout({ children }: { children: React.ReactNode }) {
  return (
    <ThemeProvider theme={theme}>
      <CssBaseline /> {/* This resets browser default styling */}
      {children}
    </ThemeProvider>
  );
}

Using the Theme in Components

You can access the theme inside any component using Material UI’s useTheme hook or by applying the theme values directly through the MUI components.

Example using useTheme:

// src/Components/Header.tsx
import { useTheme } from '@mui/material/styles';
import Typography from '@mui/material/Typography';

const Header = () => {
  const theme = useTheme();

  return (
    <header style={{ backgroundColor: theme.palette.primary.main, padding: '1rem' }}>
      <Typography variant="h4" color="secondary">
        Welcome to the Application
      </Typography>
    </header>
  );
};

export default Header;

In this example, the Header component uses the primary color from the theme for the background and the secondary color for the text. You can access any part of the theme (e.g., spacing, typography) in a similar way with useTheme.


State Management

We use Zustand for lightweight state management. The store is located in the src/store/useStore.ts file.

Example store setup:

// src/store/useStore.ts
import create from "zustand";

interface StoreState {
  counter: number;
  increment: () => void;
}

const useStore = create<StoreState>((set) => ({
  counter: 0,
  increment: () => set((state) => ({ counter: state.counter + 1 })),
}));

export default useStore;
