How to send axios delete in JavaScript to backend ReactJS

What is Send Axios Delete?

Removing data from the backend using ReactJS and Axios can be a challenging task. However, with the right approach and knowledge, you can accomplish this task easily. In this article, we will explore how to send an Axios delete request to the backend in ReactJS using JavaScript. We'll walk through two different approaches with code and explanations, as well as two working examples. So, let’s get started!

algorithm

Before we begin our discussion, it is crucial to understand the process of sending an Axios delete request to the backend when using ReactJS. Here are the steps -

• Merge Axios - Must include Axios, a popular library for forging HTTP petitions.

• Building a Clear Request - You will then use Axios to initiate a clear request. This requires specifying the Uniform Resource Locator (URL), headers (if any), and any data that needs to be transferred to the server.

• Send Request - In summary, you will use Axios to send a clear request to the server.

Method 1: Use axios deletion method

The first method involves using the Axios delete method. This is the code -

import axios from 'axios';
const deleteData = async (id) => {
   try {
      const response = await axios.delete(`https://example.com/api/data/${id}`);
      console.log(response.data);
   } catch (error) {
      console.error(error);
   }
};

In the above code, we define a function called deleteData, which takes an id parameter. Inside the function, we use the delete method of axios to send a delete request to the server. The URL we target contains the id parameter, which represents the data we want to delete. If the request is successful, we log the response data to the console. If an error occurs, we log the error to the console.

Example

In this example, we will create a delete button that can be clicked to delete the data. This is the code -

import React from 'react';
import axios from 'axios';
const DeleteButton = ({ id }) => {
   const handleDelete = async () => {
      try {
         const response = await axios.delete(`https://example.com/api/data/${id}`);
         console.log(response.data);
      } catch (error) {
         console.error(error);
      }
   };
   return (
      <button onClick={handleDelete}>
         Delete
      </button>
   );
};
export default DeleteButton;

The above code illustrates a component called "DeleteButton" that allows accepting the id attribute to build a delete request URL. When the delete button is clicked, the handleDelete function will be called, which uses the Axios delete method to send a delete request to the server and specifies the relevant id. After the request is successful, the response data will be logged in the console. Instead, if any error occurs, that error is also logged in the console.

Method 2: Use axios request method

The alternative requires using the Axios request procedure and the "delete" attribute setting of the method attribute. The following is the corresponding code snippet -

// Import Axios library
const axios = require('axios');

// Define a function to delete data
async function deleteData(id) {
   try {
   
      // Make a DELETE request to the API with the given ID
      const response = await axios({
         url: 'https://example.com/api/data/' + id,
         method: 'delete'
      });
      console.log(response.data);
   } catch (error) {
   
      // Log any errors that occur
      console.error(error);
   }
}

In this code, we define the same deleteData function as the first method. However, instead of using the Axios delete method, we use the Axios request method and set the method attribute to "Delete". If the request is successful, we log the response data to the console. If an error occurs, we log the error to the console.

Now that we've covered both methods with code and explanations, let's look at two working examples of how to send an Axios delete request to the backend in ReactJS.

Example: Delete confirmation mode

In this example, we will create a delete confirmation mode to delete the data after confirmation. Here is the code.

import React, { useState } from 'react';
import axios from 'axios';
const DeleteConfirmationModal = ({ id }) => {
   const [isOpen, setIsOpen] = useState(false);
   const handleDelete = async () => {
      try {
         const response = await axios.delete(`https://example.com/api/data/${id}`);
         console.log(response.data);
      } catch (error) {
         console.error(error);
      }
      setIsOpen(false);
   };

   return (
      <>
      <button onClick={() => setIsOpen(true)}>
         Delete
      </button>
      {isOpen && (
         <div>
            <p>Are you sure you want to delete this data?</p>
            <button onClick={handleDelete}>
               Yes, delete it
            </button>
            <button onClick={() => setIsOpen(false)}>
               Cancel
            </button>
         </div>
      )}
      </>
   );
};

export default DeleteConfirmationModal;

Output

The code above contains a component called DeleteConfirmationModal, which accepts the id attribute. When you click the delete button, a confirmation mode will appear. If the user confirms the deletion, the handleDelete function is executed. This function uses the axios delete method to send a delete request to the server and specifies the id. After the request is successful, response data will be logged to the console. Instead, if any error occurs, that error is also logged in the console. In short, the isOpen state is set to false, thus turning off confirmation mode.
