Upgrade VB to Spring Boot using Vite.js and React in Project | Remove User | Part 12

In this tutorial, we will go through the process of migrating a Visual Basic (VB) project to Spring Boot with Vite.js and React, focusing on the functionality of deleting a user from the system. This is part 12 of the series, so if you haven’t already, make sure to check out the previous parts to get a better understanding of the overall migration process.

1. Set up the project: Before we begin with the migration process, make sure you have a working Spring Boot project set up with Vite.js and React. If you haven’t done this yet, you can refer to the previous parts of this series for detailed instructions on how to set up the project.

2. Implement the Delete User functionality: Now that our project is set up, let’s move on to implementing the Delete User functionality. In the VB project, there might have been a button or a link to delete a user. We need to replicate this functionality in our React component.

3. Create a DeleteUser component: Create a new component called DeleteUser.js in the components folder of your React project. This component will contain the logic for deleting a user.

import React from 'react';

const DeleteUser = ({ userId, onDelete }) => {
  const handleDelete = () => {
    // Perform the delete operation here
    onDelete(userId);
  };

  return (
    <button onClick={handleDelete}>Delete User</button>
  );
};

export default DeleteUser;

1. Connect the component to the API: In the DeleteUser component, we need to send a request to the Spring Boot backend to delete the user. You can use Axios or any other HTTP client library to make API requests.

import axios from 'axios';

const handleDelete = () => {
  axios.delete(`http://localhost:8080/api/users/${userId}`)
    .then(() => {
      // Handle successful deletion
      onDelete(userId);
    })
    .catch((error) => {
      // Handle error
      console.error(error);
    });
};

1. Update the main App component: In the main App.js component of your React project, import the DeleteUser component and use it to delete a user.

import React, { useState } from 'react';
import DeleteUser from './components/DeleteUser';

const App = () => {
  const [users, setUsers] = useState([]);

  const handleDelete = (userId) => {
    // Update the list of users after deletion
    setUsers(users.filter(user => user.id !== userId));
  };

  return (
    <div>
      {users.map(user => (
        <div key={user.id}>
          <p>{user.name}</p>
          <DeleteUser userId={user.id} onDelete={handleDelete} />
        </div>
      )}
    </div>
  );
};

export default App;

1. Test the functionality: Finally, test the Delete User functionality in your React application. Clicking on the "Delete User" button should send a request to the Spring Boot backend to delete the user, and update the list of users displayed in the UI.

2. Conclusion: In this tutorial, we discussed how to migrate a Visual Basic project to Spring Boot with Vite.js and React, focusing on the functionality of deleting a user. By following these steps, you should now have a working Delete User functionality in your migrated project. Feel free to explore more advanced features and functionalities to further enhance your application.
