It’s no doubt, React Hooks have revolutionized the way developers manage state and lifecycle in React applications. Combined with the Fetch API, developers can implement powerful CRUD (Create, Read, Update, Delete) operations within their applications seamlessly.

In this comprehensive guide, we will dive deep into building a CRUD lab using React Hooks and Fetch API. By the end of this tutorial, you’ll have a solid understanding of how to implement CRUD operations in your React projects efficiently.

Prerequisites:

Before we dive into the implementation, ensure you have the following prerequisites installed:

  • Node.js and npm

  • Basic understanding of React.js

  • Familiarity with JavaScript ES6 syntax

Setting Up the Project:

Let’s kick things off by setting up our React project. Open your terminal and follow these steps:

Create a new React project using Create React App:

npx create-react-app react-hooks-crud-lab

Navigate to the project directory

cd react-hooks-crud-lab

Install Axios for making HTTP requests:

npm install axios

Once installed,you’re ready to start implementing the CRUD operations in your React application.

Creating Components:

We’ll create four components for our CRUD operations: Create, Read, Update, and Delete. Let’s start with the Create component.

Create Component:

Inside the src folder, create a new file named Create.js. Add the following code:

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

const Create = () => {
  const [data, setData] = useState({
    title: '',
    description: ''
  });

  const handleChange = (e) => {
    setData({ ...data, [e.target.name]: e.target.value });
  };

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      await axios.post('API_ENDPOINT', data);
      alert('Data created successfully!');
      setData({ title: '', description: '' });
    } catch (error) {
      console.error('Error creating data:', error);
    }
  };

  return (
    <div>
      <h2>Create Data</h2>
      <form onSubmit={handleSubmit}>
        <input
          type="text"
          name="title"
          placeholder="Title"
          value={data.title}
          onChange={handleChange}
        />
        <textarea
          name="description"
          placeholder="Description"
          value={data.description}
          onChange={handleChange}
        ></textarea>
        <button type="submit">Submit</button>
      </form>
    </div>
  );
};

export default Create;

Replace ‘API_ENDPOINT’ with the actual endpoint where you’ll be sending your HTTP requests.
