Differences between Spring/JSP and React/TypeScript for CRUD Operations

Differences between Spring/JSP and React/TypeScript for CRUD Operations: Language and Type-Checking: With Spring/JSP, you would typically use Java for the server-side logic. Java is a statically typed language which means you have to define the types of your variables when you declare them. However, with React, you are typically using JavaScript (or TypeScript in your case). JavaScript is a dynamically typed language. When using TypeScript, though, you get the advantage of static typing in a JavaScript environment, making your code less prone to runtime errors due to type mismatch. View Rendering: Spring MVC with JSP typically involves server-side rendering, where the HTML is constructed on the server and sent to the client. React, on the other hand, is a client-side library, so it manipulates the DOM directly in the browser. This leads to better performance and a more interactive user experience. Data Flow: In a Spring/JSP app, you would usually submit forms to send data to the server and reload the page to get updated data. With React, you can update the view in real time without a page reload, making the user experience smoother. State Management: In a traditional Spring/JSP application, the state of the application is typically managed by the server and each page reload could mean a state reset. React, on the other hand, is designed to manage state on the client side, which makes handling user input and feedback on the client side much easier and efficient. Easiest Way to Make CRUD Function Using React: Building CRUD functionality in React involves setting up components that handle the different parts of the CRUD functionality: Create, Read, Update, and Delete. Here's a general step-by-step guide: Setup your environment: Create a new React project using create-react-app with the TypeScript template. Create a List Component: This component will fetch and display a list of data from your API. You can use the fetch API to get the data.

import React, { useEffect, useState } from 'react';

const List = () => {
    const [data, setData] = useState([]);

    useEffect(() => {
        fetch('/api/data')
            .then(response => response.json())
            .then(data => setData(data));
    }, []);

    return (
        <div>
            {data.map(item => (
                <div key={item.id}>
                    {/* Display your data here */}
                </div>
            ))}
        </div>
    );
};

export default List;

3. Create a Form Component: This component will handle both creation of new items and updating existing ones. It should have form controls for all the fields of your data, and it should use controlled components to handle form state. 4. Handle Create and Update: You'll need to have functions to handle the form submissions. They should prevent the default form submission, take the data from the state, and then use fetch to send the data to the server. Depending on whether you're creating a new item or updating an existing one, you'll send a POST or PUT request. 5. Handle Delete: This could be a button next to each item in your list. When clicked, it should use fetch to send a DELETE request to the server with the id of the item to delete. 6. State and Props: Use the state in your components to hold and manage data, and pass down functions as props to handle the Create, Update, and Delete operations. Remember to use TypeScript to type your props, state, and events. This will provide you with autocompletion and help catch errors before they happen. React with TypeScript can be challenging at first but it is worth it in the long term for maintainability and reliability of the code. Also note that in real-world scenarios, you might want to consider using a state management library (like Redux or MobX) for better state management and a library like react-query or SWR for data fetching, but these aren't strictly necessary for smaller applications.
