Installation

1. Clone the Repository

   First, clone the repository to your local machine:

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

2. Navigate to the Project Directory

   cd your-repo-name

3. Install Dependencies

   Make sure you have all necessary dependencies installed by running:

   npm install

   or

   yarn install

4. Run the Development Server

   Start the Next.js development server to see the component in action:

   npm run dev

   or

   yarn dev

5. Access the Development Server

   Open your browser and navigate to:

   http://localhost:3000
   

Usage

To use the carousel component in your project, follow these steps:

1. Import and Wrap with Provider

   Make sure to wrap your component with the CarouselProvider at the top level where you want the carousel to be rendered. This will provide access to the carousel context throughout the component tree.

   import React from "react";
   import { CarouselProvider } from "./src/app/ui/projects/carouselContext";
   import Carousel from "./src/app/ui/projects/Carousel";
   
   const App = () => (
     <CarouselProvider>
       <div>
         <h1>My Carousel App</h1>
         <Carousel />
       </div>
     </CarouselProvider>
   );
   
   export default App;

2. Structure the Component

   The carousel will automatically load the predefined images and handle the transitions. The main carousel component is located at:

   src/app/ui/projects/Carousel
   

3. Customize with Props

   You can pass props to the <Carousel /> component if additional customization is needed (refer to the Props section).

Props

Currently, the carousel component does not require any external props for its basic usage. However, you can extend its functionality by adding new props based on your requirements.

For example, you can control the following properties via the CarouselProvider:

• Transition Duration: The time it takes for slides to move.
• Image Width: The image width to be translated vertically.
• Auto-play: Start and stop automatic transitions between slides.

State Management

The carousel uses a context-based state management system. The CarouselProvider component wraps the entire carousel application and provides a global state. This state can be accessed using the useCarousel hook.

Example State and Functions

• State Variables:

  • images: The array of images to be displayed.
  • currentIndex: The index of the currently visible image.
  • isTranslating: Boolean indicating if a transition is in progress.
  • isPlaying: Boolean indicating if auto-play is enabled.

• Functions:

  • handleNext(): Move to the next image.
  • handlePrev(): Move to the previous image.
  • handleStepClick(stepIndex): Jump to a specific image.

Accessing State

To access and use the carousel state and functions, use the useCarousel hook as shown below:

import React from "react";
import { useCarousel } from "./src/app/ui/projects/carouselContext";

const CarouselController = () => {
  const { handleNext, handlePrev, isPlaying, setIsPlaying } = useCarousel();

  return (
    <div>
      <button onClick={handlePrev}>Previous</button>
      <button onClick={handleNext}>Next</button>
      <button onClick={() => setIsPlaying(!isPlaying)}>
        {isPlaying ? "Pause" : "Play"}
      </button>
    </div>
  );
};

Customization

The carousel is designed to be easily customized:

1. Change Images: Replace the images in the modelSources array within the carousel context (carouselContext.js) to display different images.

   const modelSources = [
     "/path/to/your/image1.jpg",
     "/path/to/your/image2.jpg",
     // Add more images here...
   ];

2. Update Styles: The carousel is styled using CSS-in-JS (e.g., Tailwind CSS or standard CSS). Modify the styles in the Carousel component to achieve your desired look and feel.

3. Modify Transitions: Adjust the transition duration or easing function inside the context file to alter the speed and smoothness of image transitions.
