Cool Ways of Working with Axios in ReactJS

Axios is a popular JavaScript library used to make HTTP requests from web browsers. It can be used with ReactJS to fetch data from APIs and update the user interface. Here are some cool ways to work with Axios in ReactJS:

1. Use Axios Interceptors

Axios Interceptors allow you to intercept requests or responses before they are handled by .then() or .catch() methods. You can use Axios Interceptors to handle authentication, logging, or error handling in your ReactJS application. Here is an example of how to use Axios Interceptors:

// Add a request interceptor
axios.interceptors.request.use(
  function (config) {
    // Do something before request is sent
    return config;
  },
  function (error) {
    // Do something with request error
    return Promise.reject(error);
  }
);

// Add a response interceptor
axios.interceptors.response.use(
  function (response) {
    // Any status code that lie within the range of 2xx cause this function to trigger
    // Do something with response data
    return response;
  },
  function (error) {
    // Any status codes that falls outside the range of 2xx cause this function to trigger
    // Do something with response error
    return Promise.reject(error);
  }
);

2. Use Async/Await

Async/Await is a modern JavaScript feature that makes it easy to work with promises. You can use Async/Await with Axios to make your code more readable and easier to understand. Here is an example of how to use Async/Await with Axios:

async function getData() {
  try {
    const response = await axios.get('https://api.example.com/data');
    console.log(response.data);
  } catch (error) {
    console.error(error);
  }
}

3. Use Axios Cancel Tokens

Axios Cancel Tokens allow you to cancel a request before it is completed. This can be useful if the user navigates away from a page or if the user performs another action before the request is completed. Here is an example of how to use Axios Cancel Tokens:

const CancelToken = axios.CancelToken;
const source = CancelToken.source();

axios
  .get('/user/12345', {
    cancelToken: source.token,
  })
  .catch(function (thrown) {
    if (axios.isCancel(thrown)) {
      console.log('Request canceled', thrown.message);
    } else {
      // handle error
    }
  });

axios.post(
  '/user/12345',
  {
    name: 'new name',
  },
  {
    cancelToken: source.token,
  }
);

// cancel the request (the message parameter is optional)
source.cancel('Operation canceled by the user.');

4. Use Axios Instances

Axios Instances allow you to create multiple instances of Axios with different configurations. This can be useful if you need to make requests to different APIs with different headers or authentication methods. Here is an example of how to use Axios Instances:

const instance = axios.create({
  baseURL: 'https://api.example.com',
  headers: {
    'X-Custom-Header': 'foobar',
  },
});

instance
  .get('/data')
  .then((response) => {
    console.log(response.data);
  })
  .catch((error) => {
    console.error(error);
  });

Conclusion

Axios is a powerful library that can help you make HTTP requests from your ReactJS application. By using these cool ways of working with Axios, you can improve the performance, readability, and reliability of your code.
