Registration Form

A dynamic User Registration Form built with React, utilizing async/await and promises for seamless data handling. Users can register with their name and email, and view a real-time list of registered users, showcasing modern front-end development practices.

Overview Of What I Built

The User Registration Form is a React application designed to allow users to register by entering their name and email. The application captures user data asynchronously, leveraging promises and async/await for a smooth user experience. It provides immediate feedback on registration success and displays a list of registered users.

App Features

• User Registration: Users can enter their name and email to register.
• Asynchronous Submission: The registration process simulates a delay, ensuring that users can see a loading indicator while their data is processed.
• Success Message: Upon successful registration, a confirmation message is displayed.
• User List: Registered users can be viewed dynamically without page reloads.
• Responsive Design: The application is designed to work seamlessly across various devices.

Implementations

Asynchronous Data Handling

The app uses asynchronous JavaScript to handle form submissions effectively. The main components that enable this functionality are:

1. Promises: The handleSubmit function uses a promise to simulate a network request when submitting user data. This mimics real-world scenarios where data is often sent to a server and awaits a response.
2. Async/Await: The async keyword is used in the handleSubmit function, allowing the code to pause execution until the promise resolves. This creates a more readable and manageable way to handle asynchronous operations compared to traditional callback methods.

User Form Component

The UserForm component handles user input and form submission. It manages the form state (name and email) using React's useState hook.

• Input Handling: The component captures user input in real-time and updates the state accordingly.
• Form Submission: On submission, the user data is processed, and a success message is displayed if registration is successful.

User List Component

The UserList component displays a list of registered users. It receives the users' data as props and dynamically renders them based on the state in the parent App component.

Main Application Logic

The App component is the central hub of the application. It maintains the state of registered users and controls the visibility of the user list.

• State Management: The app uses useState to manage user data and the visibility of the user list.
• Add User Functionality: When a new user is added, the app updates the state and toggles the visibility of the user list.

How the App Works

1. User Input: The user fills out the registration form with their name and email.
2. Form Submission: Upon clicking the submit button, the handleSubmit function is invoked.
   • The function prevents the default form submission behavior and sets a loading state.
   • A promise simulates the processing of user data, mimicking a network request.
   • Once the promise resolves successfully, the user data is captured and added to the user list.
   • A success message is displayed, and the input fields are cleared for new entries.
3. View Registered Users: The user can click the "View Registered Users" button to toggle the visibility of the registered users list.
