React: Slideshow App | Fresco Play Hackerrank

Why React Slideshow Apps Matter

In the ever-evolving landscape of web development, React has become the go-to library for building scalable, user-friendly applications. From enterprise dashboards to lightweight interactive apps, React powers a massive portion of the modern internet.

One exciting beginner-friendly project that highlights React’s versatility is the Slideshow App, a Hackerrank-style challenge also seen in Fresco Play assignments. It’s simple to build but provides developers with hands-on experience in state management, UI navigation, and component design.

This tutorial not only explains how to build a React Slideshow App step by step but also explores its real-world applications, how enterprises can extend such apps, and why projects like this improve a developer’s problem-solving and coding skills.

What is a React Slideshow App?

A Slideshow App in React is a lightweight application where users can cycle through slides containing titles and text. Navigation is handled using Next, Prev, and Restart buttons, with built-in logic to disable buttons when not needed.

This project demonstrates key React principles:

• State management with useState
• Conditional rendering
• Reusable components
• Interactive user experience

Business and Learning Relevance

Why should you care about a Slideshow App? Beyond being a coding exercise, this app has multiple implications:

• Enterprise Use Cases: Training apps, onboarding flows, presentations, product tours.
• Hackerrank/Fresco Play Practice: Perfect for clearing React coding assessments.
• IT Infrastructure Teams: Can integrate with AI-driven content personalization.
• Cloud Optimization: Hosting React apps on AWS Amplify or Azure Static Web Apps helps reduce cloud cost.

Environment Setup

Before coding, ensure the following versions are installed:

• React Version: 16.13.1 (stable and Hackerrank-compatible)
• Node Version: ^12.18.3
• Package Manager: npm or yarn

You’ll also need basic familiarity with React hooks (useState) and JSX.

Project Requirements (Hackerrank/Fresco Play Specs)

The Slideshow App requirements are usually defined as follows:

1. The Slides component takes an array of slides as a prop.
2. The first slide loads by default.
3. The Next button moves forward but is disabled at the last slide.
4. The Prev button moves backward but is disabled at the first slide.
5. The Restart button resets the slideshow to the first slide.
6. At least one slide must always be present.

This ensures structured navigation logic and clean user experience.

Code Implementation

1. Slides.js Component

This is the core logic of the Slideshow App.

import React, { useState } from 'react';
function Slides({ slides }) {
  const [currentSlideIndex, setCurrentSlideIndex] = useState(0);
  const goToNextSlide = () => {
    if (currentSlideIndex < slides.length - 1) {
      setCurrentSlideIndex(currentSlideIndex + 1);
    }
  };
  const goToPrevSlide = () => {
    if (currentSlideIndex > 0) {
      setCurrentSlideIndex(currentSlideIndex - 1);
    }
  };
  const restartSlides = () => setCurrentSlideIndex(0);
  const { title, text } = slides[currentSlideIndex];
  return (
    <div>
      <div id="navigation" className="text-center">
        <button
          data-testid="button-restart"
          className="small outlined"
          onClick={restartSlides}
          disabled={currentSlideIndex === 0}
        >
          Restart
        </button>
        <button
          data-testid="button-prev"
          className="small"
          onClick={goToPrevSlide}
          disabled={currentSlideIndex === 0}
        >
          Prev
        </button>
        <button
          data-testid="button-next"
          className="small"
          onClick={goToNextSlide}
          disabled={currentSlideIndex === slides.length - 1}
        >
          Next
        </button>
      </div>
      <div id="slide" className="card text-center">
        <h1 data-testid="title">{title}</h1>
        <p data-testid="text">{text}</p>
      </div>
    </div>
  );
}
export default Slides;

2. App.js Component

This file integrates the Slides component with app-level logic.

import React from 'react';
import './App.css';
import 'h8k-components';
import Slides from './components/Slides';
const title = "Slideshow App";
function App({ slides }) {
  return (
    <div>
      <h8k-navbar header={title}></h8k-navbar>
      <div className="App">
        <Slides slides={slides} />
      </div>
    </div>
  );
}
export default App;

3. Index.js Component

Here, we define our slides dataset and render the app.

import React from 'react';
import ReactDOM from 'react-dom';
import './index.css';
import App from './App';
import registerServiceWorker from './registerServiceWorker';
import { applyPolyfills, defineCustomElements } from 'h8k-components/loader';
const SLIDES = [
        {
            title: "Welcome to Slideshow App",
            text: "Slideshow App, a simple yet impactful application that allows users to navigate through a collection of slides."
        },
        {
            title: "The project requirements outline.",
            text: "The Slides component should take an array of slides as a prop. Each slide is represented by an object with two properties: title (string) and text (string)."
        },
        {
            title: "Clicking the 'Next' button",
            text: "Clicking the 'Next' button should display the next slide. This button should be disabled when the current slide is the last one."
        },
        {
            title: "Clicking the 'Prev' button",
            text: "Clicking the 'Prev' button should display the previous slide. This button should be disabled when the current slide is the first one."
        },
        {
            title: "Clicking the 'Restart' button",
            text: " Clicking the 'Restart' button should return the app to the first slide. This button should be disabled when the current slide is the first one."
        },
        {
            title: "Great job!",
            text: "You made it, have a nice day and see you next time!"
        }
    ];
ReactDOM.render(<App slides={SLIDES} />, document.getElementById('root'));
registerServiceWorker();
applyPolyfills().then(() => {
  defineCustomElements(window);
});
