Design a Questionnaire Program using ReactJS
A step-by-step guide to creating a quiz application using ReactJS, class components, and Bootstrap is presented below. This tutorial is primarily based on the GeeksforGeeks tutorial updated in 2025.
**1. Setup the React Project**
To initiate the project, use the following command in your terminal:
```bash npm create vite@latest quiz --template react ```
Navigate into the project folder:
```bash cd quiz ```
**2. Install Required Modules**
Install Bootstrap into your project to use its styling components:
```bash npm install bootstrap ```
Optionally, you can install `react-bootstrap` for React-specific Bootstrap components, but the example uses Bootstrap CSS-loaded classes primarily.
**3. Project Structure**
Inside the `src` directory, create a folder named `components`. The folder should contain the following files (all using class components):
- `Option.js`: Represents an individual answer option. - `Question.js`: Displays the question and its options. - `QuestionBank.js`: Stores the array of quiz questions. - `Score.js`: Displays the final score after quiz completion.
The overall file tree under `src` looks like:
``` src/ ├── components/ │ ├── Option.js │ ├── Question.js │ ├── QuestionBank.js │ └── Score.js ├── App.js └── index.js ```
**4. Import Bootstrap CSS**
In your `src/main.jsx` or `src/index.js`, import Bootstrap CSS to apply Bootstrap styling globally:
```javascript import 'bootstrap/dist/css/bootstrap.min.css'; ```
**5. Create Core Components Using Class Components**
Examples of essential class components:
- **QuestionBank.js**
This file exports the data, an array of question objects with text and options.
- **Option.js**
Displays a single answer option and handles click events to select an answer.
- **Question.js**
Shows the current question and its related options. Manages rendering of options using `Option` components.
- **Score.js**
Displays the user's final quiz score and can provide a button to restart the quiz.
**6. Implement App.js**
In `App.js`, create a class component that manages quiz state:
- Track current question index. - Track selected answers and score. - Provide methods to handle selecting options and moving to next question. - Render the `Question` component or the `Score` component conditionally after the quiz ends.
**7. Styling and Bootstrap Use**
- Use Bootstrap classes such as `container`, `btn`, `btn-primary`, `mt-5` in your JSX to style buttons, layout, and spacing.
Following these steps, you can build a quiz application using ReactJS, class components, and Bootstrap. For more details on each component, please refer to the GeeksforGeeks tutorial from 2025 or additional resources.
A suggested method for creating a quiz application that utilizes technology like ReactJS, class components, and Bootstrap, could be the implementation of a Trie data structure for efficient management of questions and options.
Additionally, the Trie technology can help optimize the process of locating questions and their related answers in the QuestionBank, thereby enhancing the overall application's performance and user experience.
