React js CRUD Operation Using Javascript
React.js is a popular JavaScript library for building user interfaces. It is often used to create single-page applications for web and mobile platforms. In this article, we’ll explore how to perform CRUD (Create, Read, Update, Delete) operations in a React.js application using JavaScript.
Setting Up the Environment
To get started, make sure you have Node.js installed on your system. You can download it from the official Node.js website and follow the installation instructions. Once Node.js is installed, you can use npm (Node Package Manager) to install the create-react-app package, which will help you create a new React.js project with a few simple commands:
$ npx create-react-app my-crud-app
$ cd my-crud-app
$ npm start
Creating CRUD Operations
Once your React.js project is set up, you can start building the CRUD operations. You’ll need to create components for each of the CRUD operations, such as Create, Read, Update, and Delete. For example, you can create a form component for creating new items, a list component for displaying existing items, and individual item components for updating and deleting items.
Below is an example of a simple form component for creating new items:
```
import React, { useState } from 'react';
const CreateForm = () => {
const [item, setItem] = useState('');
const handleSubmit = (e) => {
e.preventDefault();
// Add code to save the new item to the database
// ...
}
return (
setItem(e.target.value)} />
)
}
export default CreateForm;
```
Handling State and Data
React.js uses a concept called “state” to manage data within a component. You can use the useState hook to create state variables and the useEffect hook to fetch data from an external API or database. In the above example, we used the useState hook to create a state variable for the new item and the handleSubmit function to handle the form submission.
Conclusion
In this article, we explored how to perform CRUD operations in a React.js application using JavaScript. We covered setting up the environment, creating CRUD components, handling state and data, and more. With this knowledge, you can start building your own CRUD applications in React.js and take your web development skills to the next level.
