DEMO CRUD USE DATA ARRAY ON REACT WITH NEXT JS
React.js and Next.js are popular JavaScript libraries for building user interfaces and web applications. In this article, we will demonstrate how to perform CRUD operations using data arrays in a React application built with Next.js. This will give you a better understanding of how to manage and manipulate data in a React application using Next.js.

Setting Up the Project
First, make sure you have Node.js and npm installed on your machine. Then, create a new Next.js project by running the following commands:
npx create-next-app demo-crud-app
cd demo-crud-app
npm run dev
This will create a new Next.js project and start the development server. You can then open your browser and navigate to http://localhost:3000 to see the default Next.js starter application.
Implementing CRUD Operations
Now that we have our Next.js project set up, let’s start implementing the CRUD operations using data arrays in a React component. We will create a simple todo list application to demonstrate this.
First, create a new file called Todos.js inside the pages directory. Here’s an example of how you can implement CRUD operations in this file:
import React, { useState } from 'react';
const Todos = () => {
const [todos, setTodos] = useState([
{ id: 1, text: 'Learn React' },
{ id: 2, text: 'Build a Next.js app' },
]);
const addTodo = (text) => {
const newTodo = {
id: todos.length + 1,
text,
};
setTodos([...todos, newTodo]);
};
const removeTodo = (id) => {
setTodos(todos.filter((todo) => todo.id !== id));
};
return (
Todo List
-
{todos.map((todo) => (
- {todo.text}
))}
);
};
export default Todos;
This is a simple example of implementing CRUD operations in a React component using data arrays. You can now use this Todos component in your Next.js application to manage a list of todos.
Conclusion
In this article, we have demonstrated how to perform CRUD operations using data arrays in a React application built with Next.js. You can use these concepts to create more complex web applications with Next.js that involve managing and manipulating data.
