Lesson 2 - Build Form Profile App Using Multi-input Form Data

Building Form Profile App

Step-by-Step Procedure to Implement React Form Profile App

1. Setting Up the Project

Create a New React Project: Run the following command to create a new React project:
```
npx create-react-app react-formProfile-app
cd react-formProfile-app
```
Install Bootstrap CSS: Install Bootstrap using npm:
```
npm install bootstrap
```
Import Bootstrap in the main.jsx file:
```
import 'bootstrap/dist/css/bootstrap.min.css';
```
Setup Folder Structure: Create a components folder inside the src directory:
```
src/
|-- components/
    |-- FormProfile.jsx
|-- AppFormProfile.jsx
```

2. Implement the Parent Component: `AppFormProfile.jsx`

The parent component manages the state for the form data and profiles, and passes the necessary props to the child component.

Code for AppFormProfile.jsx:

import React, { useState } from 'react';
import FormProfile from './components/FormProfile';
import 'bootstrap/dist/css/bootstrap.min.css';

function AppFormProfile() {
  const [formData, setFormData] = useState({
    userImage: './src/assets/IMG_0003.JPG', // Replace with a real image URL,
    name: '',
    email: '',
    profession: ''
  });

  const [profiles, setProfiles] = useState([]);

  const handleChange = (event) => {
    const { name, value } = event.target;
    setFormData({
      ...formData,  // create a copy of the formData array.
      [name]: value
    }); //update form data input
  };

  const handleSubmit = (event) => {
    event.preventDefault();
    setProfiles([...profiles, formData]);
    setFormData({ userImage: '', name: '', email: '', profession: '' });
  }; //clear form inputs

  return (
    <div className="container mt-5">
      <h1 className="text-center">React Profile App</h1>
      <form onSubmit={handleSubmit} className="mb-4">
        <div className="mb-3">
          <input
            type="text"
            name="userImage"
            value={formData.userImage}
            onChange={handleChange}
            placeholder="Image URL"
            className="form-control"
          />
        </div>
        <div className="mb-3">
          <input
            type="text"
            name="name"
            value={formData.name}
            onChange={handleChange}
            placeholder="Name"
            className="form-control"
          />
        </div>
        <div className="mb-3">
          <input
            type="email"
            name="email"
            value={formData.email}
            onChange={handleChange}
            placeholder="Email"
            className="form-control"
          />
        </div>
        <div className="mb-3">
          <input
            type="text"
            name="profession"
            value={formData.profession}
            onChange={handleChange}
            placeholder="Profession"
            className="form-control"
          />
        </div>
        <button type="submit" className="btn btn-primary">Add Profile</button>
      </form>
      <div className="profile-container d-flex flex-wrap gap-4">
        {profiles.map((profile, index) => (
          <FormProfile
            key={index}
            userImage={profile.userImage}
            name={profile.name}
            email={profile.email}
            profession={profile.profession}
          />
        ))}
      </div>
    </div>
  );
}

export default AppFormProfile;

3. Implement the Child Component: `FormProfile.jsx`

The child component receives props from the parent and renders the user profile.

Code for FormProfile.jsx:

import React from 'react';
import PropTypes from 'prop-types';

function FormProfile({ userImage, name, email, profession }) {
  return (
    <div className="user-profile d-flex border p-3 rounded">
      <div className="left-item me-3">
        <img src={userImage} alt={name} className="img-fluid rounded" style={{ width: '100px', height: '100px' }} />
      </div>
      <div className="right-item d-flex flex-column">
        <h5>{name}</h5>
        <p>{email}</p>
        <p>{profession}</p>
      </div>
    </div>
  );
}

FormProfile.propTypes = {
  userImage: PropTypes.string.isRequired,
  name: PropTypes.string.isRequired,
  email: PropTypes.string.isRequired,
  profession: PropTypes.string.isRequired,
};

export default FormProfile;

4. Styling with Bootstrap

Leverage Bootstrap classes for styling. Use d-flex, flex-row, and flex-column for layouts. Add custom styles in App.css if necessary.

5. Run the Application

Start the application using the following command:

npm run dev

Final Output

The app will display a form at the top for adding profiles. Below the form, profiles will be displayed in a flexbox layout with images on the left and details on the right.

Summary

This walkthrough demonstrates how to:

Lift state up in the parent component.
Pass props to child components.
Use Bootstrap for responsive styling.
Manage forms and lists dynamically in React.
