Hey guys! Let's dive into how to implement the individual zone page for our awesome exhibition navigation app. This page is super important because it's where users will find all the cool stalls and areas within a specific zone. So, let's make it user-friendly and visually appealing!

Overview

What's the Goal?

The main goal of this page is to display all the stalls available in a selected zone in a clear and organized manner. Users should be able to easily navigate and find the stalls they are interested in. Think of it as a virtual directory for each zone.

Key Features

  • Stall Cards: Display each stall as a card, following the design provided in Figma. This will give users a visual representation of each stall.
  • Scan QR Button: Place a prominent scan QR button at the top of the page. This allows users to quickly scan QR codes and get more information about a stall.
  • Navigation: Clicking on a stall card should navigate the user to the relevant stall page.

Design Reference

Make sure to refer to the Figma design to ensure the page looks consistent with the overall app design. You can find the design here.

Detailed Implementation Steps

1. Setting Up the Page Structure

First, let's set up the basic structure of the individual zone page. This involves creating the necessary components and layout.

  • Create a New Component: If you're using React, create a new component called ZonePage. For other frameworks, create a similar component or page.
  • Basic Layout: Set up a basic layout with a header, a section for the scan QR button, and a section for displaying the stall cards. Use CSS or your framework's styling system to create a visually appealing layout. Think about using grid or flexbox to arrange the stall cards neatly.
  • Import Necessary Components: Import any necessary components, such as the StallCard component (which we'll create later) and any UI elements you need.

2. Implementing the Scan QR Button

The scan QR button is a crucial element for quick access to stall information. Let's implement it.

  • Add the Button: Add a button element to the top of the page. Style it according to the design.
  • Functionality: Implement the functionality for scanning QR codes. You might need to use a library for QR code scanning. When the user scans a QR code, navigate them to the appropriate stall page based on the QR code data. For now, you can simulate this functionality with a simple alert or console log.

3. Creating the Stall Card Component

Each stall should be displayed as a card. Let's create a StallCard component.

  • Create a New Component: Create a new component called StallCard. This component will be responsible for displaying the information for a single stall.
  • Props: Define the props for the StallCard component. These props should include the stall name, description, image, and any other relevant information.
  • Display Information: Use the props to display the stall information in the card. Style the card according to the design. Make sure the card is visually appealing and easy to read.

4. Fetching and Displaying Stall Data

Now, let's fetch the stall data and display it on the page. Since the backend is not ready yet, we'll use mock data.

  • Create Mock Data: Create a JSON file or a JavaScript object with mock data for the stalls. Each stall object should include the stall name, description, image URL, and any other relevant information. Example Mock Data:
[
 {
 "id": "1",
 "name": "Awesome Stall 1",
 "description": "This is a description for Awesome Stall 1.",
 "image": "https://example.com/stall1.jpg"
 },
 {
 "id": "2",
 "name": "Amazing Stall 2",
 "description": "This is a description for Amazing Stall 2.",
 "image": "https://example.com/stall2.jpg"
 }
]
  • Fetch Data: In the ZonePage component, fetch the mock data. You can use the fetch API or any other method to load the data.
  • Display Stall Cards: Map over the stall data and create a StallCard component for each stall. Pass the stall data as props to the StallCard component.
import React from 'react';
import StallCard from './StallCard';
import mockData from './mockData.json';

function ZonePage() {
 return (
 <div>
 {/* Scan QR Button */}
 <button>Scan QR Code</button>
 {/* Stall Cards */}
 {mockData.map(stall => (
 <StallCard key={stall.id} stall={stall} />
 ))}
 </div>
 );
}

export default ZonePage;

5. Implementing Navigation

When a user clicks on a stall card, they should be navigated to the relevant stall page. Let's implement this functionality.

  • Add Click Handler: Add a click handler to the StallCard component. When the card is clicked, navigate the user to the stall page.
  • Navigation: Use your framework's navigation system to navigate to the stall page. Pass the stall ID or any other relevant information as a parameter in the URL.
import React from 'react';
import { useNavigate } from 'react-router-dom';

function StallCard({ stall }) {
 const navigate = useNavigate();

 const handleClick = () => {
 navigate(`/stall/${stall.id}`);
 };

 return (
 <div onClick={handleClick}>
 <h3>{stall.name}</h3>
 <p>{stall.description}</p>
 <img src={stall.image} alt={stall.name} />
 </div>
 );
}

export default StallCard;

Acceptance Criteria

To ensure the individual zone page is implemented correctly, make sure to meet the following acceptance criteria:

  • Navigation: When a stall card is clicked, the user should be navigated to the relevant stall page.
  • Data Display: The stalls related to each zone should be obtained from the backend (using mock data for now).
  • Visual Design: The page should follow the design provided in Figma.

Tips and Best Practices

  • Use Reusable Components: Create reusable components for the stall cards and other UI elements. This will make your code more maintainable and easier to update.
  • Optimize Performance: Optimize the performance of the page by using techniques such as lazy loading images and virtualizing long lists.
  • Test Thoroughly: Test the page thoroughly to ensure it works correctly on different devices and browsers.
  • Error Handling: Implement proper error handling to handle cases where the data cannot be loaded or the navigation fails.

Conclusion

Implementing the individual zone page involves setting up the page structure, creating the stall card component, fetching and displaying stall data, and implementing navigation. By following these steps and best practices, you can create a user-friendly and visually appealing page that helps users navigate the exhibition effectively. Remember to refer to the Figma design and test your implementation thoroughly. Good luck, and have fun coding!
