Introduction:
In the dynamic world of React development, mastering CRUD (Create, Read, Update, Delete) operations is essential for building interactive and data-driven applications. By combining the capabilities of React with JSON Server and the Fetch API, developers can efficiently manage data manipulation tasks and interact with server-side resources. This article delves into how React developers can leverage JSON Server and the Fetch API to perform CRUD operations effectively, enabling them to create robust and responsive applications. There is alternative to the fetch API which is ‘Axios’ more on that later.

Understanding CRUD Operations in the Context of React:
Before delving into the practical implementation of CRUD operations within a React application, it is crucial to understand the fundamental concepts of CRUD:
?
1. Create (POST): Adding new data entries to a server or database.
2. Read (GET): Retrieving existing data entries from a server or database.
3. Update (PUT/PATCH): Modifying and updating existing data entries on the server.
4. Delete (DELETE): Removing data entries from the server or database.

Mastering CRUD Operations with React and JSON Server:
React's component-based architecture and state management capabilities make it an ideal framework for implementing CRUD operations seamlessly. By integrating JSON Server as a mock API and utilizing the Fetch API within React components, developers can create dynamic and interactive applications. Here's how you can master CRUD operations with React and JSON Server:
?
1. Setting Up JSON Server in a React Project:
?? - Install JSON Server using npm:
????
bash
???? npm install -g json-server
????
?? - Create a JSON file with sample data and define routes:
????
json
???? {
?????? "users": [
???????? { "id": 1, "name": "Garnacho" },
???????? { "id": 2, "name": "Rashford" }
?????? ]
???? }
????
?? - Start the JSON Server:
????
Bash/terminal
???? json-server --watch db.json
????

2. Implementing CRUD Operations with Fetch API in React Components:
?? - Fetching Data (GET) ‘Read in our CRUD’ within a React component:
????
javascript
???? fetch('https://localhost:3000/users')
?????? .then(response => response.json())
?????? .then(data => console.log(data));
????
?? - Adding Data (POST) from a React form submission:
????
javascript
???? fetch('https://localhost:3000/users', {
?????? method: 'POST',
?????? headers: { 'Content-Type': 'application/json' },
?????? body: JSON.stringify({ name: Macguire })
???? });
????
?? - Updating Data (PUT/PATCH) ‘Update in our CRUD’ based on user interactions:
????
javascript
???? fetch('https://localhost:3000/users/1', {
?????? method: 'PUT',
?????? headers: { 'Content-Type': 'application/json' },
?????? body: JSON.stringify({ name: Onana })
???? });
????
?? - Deleting Data (DELETE) ‘Delete in our CRUD’ based on user actions:
????
javascript
???? fetch('https://localhost:3000/users/2', {
?????? method: 'DELETE'
???? });
????
Conclusion:
By harnessing the power of React, JSON Server, and the Fetch API, developers can elevate their CRUD operations within React applications to create responsive and data-driven user experiences. Understanding the principles of CRUD operations and integrating them seamlessly within a React project empowers developers to build robust and efficient applications. Embrace the potential of React for managing data interactions and take your development skills to new heights with seamless CRUD operations integration.
