VueJS - Making API Calls with Axios

Making API Calls with Axios in VueJS

Axios is a popular HTTP client library that allows you to make API calls in a VueJS application. This guide covers how to use Axios to perform GET, POST, PUT, and DELETE requests in VueJS.

Installing Axios

To use Axios in your VueJS project, you need to install it via npm or yarn:

# Install Axios via npm
$ npm install axios

# Install Axios via yarn
$ yarn add axios
                

Basic API Calls

GET Request

Perform a GET request to retrieve data from an API:

// APIComponent.vue



                

POST Request

Perform a POST request to send data to an API:

// APIComponent.vue



                

Advanced API Calls

PUT Request

Perform a PUT request to update data on an API:

// APIComponent.vue



                

DELETE Request

Perform a DELETE request to remove data from an API:

// APIComponent.vue



                

Interceptors

Axios interceptors allow you to intercept requests or responses before they are handled by then or catch:

// axios.js
import axios from 'axios';

// Request interceptor
axios.interceptors.request.use(config => {
  console.log('Request:', config);
  // Add authorization token or other headers here
  return config;
}, error => {
  return Promise.reject(error);
});

// Response interceptor
axios.interceptors.response.use(response => {
  console.log('Response:', response);
  return response;
}, error => {
  return Promise.reject(error);
});

export default axios;
                

Best Practices

Follow these best practices when making API calls in VueJS:

• Handle Errors Gracefully: Always handle errors to provide a better user experience and prevent application crashes.
• Use Environment Variables: Store API endpoints and other configuration in environment variables to keep your code clean and secure.
• Organize API Calls: Organize your API calls in a separate service or module to keep your components clean and maintainable.
• Use Interceptors: Use Axios interceptors to handle common tasks such as setting headers and logging requests/responses.
• Cache Responses: Cache API responses where appropriate to improve performance and reduce unnecessary network requests.

Summary

This guide provided an overview of making API calls with Axios in VueJS, including how to perform GET, POST, PUT, and DELETE requests, use interceptors, and follow best practices. By understanding and utilizing these techniques, you can effectively interact with RESTful services in your VueJS application.
