In modern web development, RESTful APIs are widely used for communication between frontend and backend systems. One common task is performing update operations, where we need to update data on the server. In this blog post, we’ll explore how to perform update operations with RESTful APIs using JavaScript.

Introduction to RESTful APIs

RESTful APIs follow a set of principles for building web services. They are based on the HTTP protocol methods, where each method has a specific purpose. In the context of update operations, the PUT or PATCH method is commonly used.

The PUT method is used to completely replace an existing resource, while the PATCH method is used to partially update an existing resource. Both methods require sending the updated data to the server.

Update Operations with Axios

Axios is a popular JavaScript library for making HTTP requests. It provides a simple and intuitive API for performing various HTTP methods, including PUT and PATCH.

To perform an update operation with Axios, we need to make a PUT or PATCH request with the updated data. Here’s an example:

import axios from 'axios';

const updateData = async (id, updatedData) => {
  try {
    const response = await axios.put(`/api/resource/${id}`, updatedData);
    console.log(response.data);
  } catch (error) {
    console.error(error);
  }
};

// Call the updateData function
const id = '12345';
const updatedData = { name: 'John Doe', age: 30 };
updateData(id, updatedData);

In the example above, we import Axios and define an updateData function that takes the resource id and updated data as parameters. We then make a PUT request to the server with the specified resource ID and updated data. Finally, we log the response data if the request is successful or log any errors encountered.

Update Operations with Fetch API

The Fetch API is a newer and native JavaScript API for making HTTP requests. It provides a more modern and streamlined approach compared to traditional methods like XMLHttpRequest.

To perform an update operation with the Fetch API, we need to make a PUT or PATCH request with the updated data. Here’s an example:

const updateData = async (id, updatedData) => {
  try {
    const response = await fetch(`/api/resource/${id}`, {
      method: 'PUT', // or 'PATCH'
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify(updatedData),
    });

    const data = await response.json();
    console.log(data);
  } catch (error) {
    console.error(error);
  }
};

// Call the updateData function
const id = '12345';
const updatedData = { name: 'John Doe', age: 30 };
updateData(id, updatedData);

In the example above, we define an updateData function that takes the resource id and updated data as parameters. We then use the Fetch API to make a PUT or PATCH request to the server with the specified resource ID and updated data. Finally, we parse the response data as JSON and log it if the request is successful or log any errors encountered.

Conclusion

Performing update operations with RESTful APIs in JavaScript is a common task in web development. In this blog post, we explored how to perform update operations using Axios and the Fetch API. Both options provide convenient ways to make PUT or PATCH requests and handle the response data. Choose the option that best fits your project and coding style.
