Update Data with API in React JS

In this tutorial, we will learn how to update data with an API using React JS and Node. We will create a simple CRUD (Create, Read, Update, Delete) application where we can update existing data using React and Node.js.

Setting up the Project

First, we need to set up our project by creating a new React app and a Node.js server. To create a new React app, run the following command in your terminal:

$ npx create-react-app react-crud

Next, we need to set up a Node.js server to handle our API requests. You can create a new directory for your server and install the necessary dependencies by running the following commands:

$ mkdir node-server
$ cd node-server
$ npm init -y
$ npm install express body-parser cors

Once our project is set up, we can start writing the code to update data with an API in React JS.

Updating Data with an API

In our React app, we will create a form component to update the existing data. We will send a PUT request to the server with the updated data, and the server will handle the request and update the data in the database.

Here’s an example of how you can update data with an API in React JS:

“`jsx
import React, { useState } from ‘react’;
import axios from ‘axios’;

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

const handleSubmit = async (e) => {
e.preventDefault();
try {
const response = await axios.put(‘http://localhost:3001/update’, { data });
console.log(response.data);
} catch (error) {
console.error(error);
}
}

return (

setData(e.target.value)} />
Update Data

);
}

export default UpdateData;
“`

In the above example, we have a form component that takes user input and sends a PUT request to the server using axios. The server will handle the request and update the data in the database.

Conclusion

In this tutorial, we learned how to update data with an API in React JS. We created a simple CRUD application with a form component to update existing data and sent a PUT request to the server to handle the update. This CRUD application allows us to perform all the basic operations on the data, and we can use it as a template for more complex applications.
