Axios API

Introduction:

àIn the world of web development, communication between the front-end and back-end is crucial. Axios is a popular JavaScript library used for making HTTP requests from the browser., We will explore how to use Axios to interact with APIs, catering to beginners at the engineer level.

Step1: Installing Axios

àWe need to install Axios in our project. We can do this easily using npm (Node Package Manager) or yarn. Open your terminal and type:

npm install axios

Step 2: Importing Axios

àOnce Axios is installed, we need to import it into our project. In your JavaScript file, import Axios like this:

import axios from 'axios';

Step 3: Making GET Requests

Now that Axios is set up, let's start making HTTP requests. To make a GET request to an API endpoint, use the following syntax:

axios.get('https://api.example.com/data')

  .then(response => {

    console.log(response.data);

  })

  .catch(error => {

    console.error('Error fetching data:', error);

  });

Step 4: Making POST Requests

àPOST requests are used to send data to the server. Here's how you can make a POST request with Axios:

axios.post('https://api.example.com/post-data', { key: 'value' })

  .then(response => {

    console.log('Data sent successfully:', response.data);

  })

  .catch(error => {

    console.error('Error sending data:', error);

  });

Step 5: Handling Responses

àAxios provides a convenient way to handle responses using promises. You can access the response data inside the .then() block and handle errors in the .catch() block.

Step 6:

àInterceptors (Optional) Interceptors are functions that Axios calls for every request and response. They can be used for tasks like logging requests or modifying headers. Here's an example of adding a request interceptor

axios.interceptors.request.use(config => {

  // Do something before request is sent

  console.log('Request sent:', config);

  return config;

}, error => {

  // Do something with request error

  console.error('Error sending request:', error);

  return Promise.reject(error);

});

Step 7: Conclusion

àAfter Completed this steps your Axios APi is integerated in your React-native project.

àAxios is a helpful tool for web developers. It's like a messenger between the front and back ends of a website or web app.

àWith Axios, you can ask for information from other websites or send information to them.

àFor example, if you're building a weather app, Axios can help you ask a weather website for the current weather information.
