Axios handling errors

Solution 1:

Actually, it's not possible with axios as of now. The status codes which falls in the range of 2xx only, can be caught in .then().

A conventional approach is to catch errors in the catch() block like below:

axios.get('/api/xyz/abcd')
  .catch(function (error) {
    if (error.response) {
      // Request made and server responded
      console.log(error.response.data);
      console.log(error.response.status);
      console.log(error.response.headers);
    } else if (error.request) {
      // The request was made but no response was received
      console.log(error.request);
    } else {
      // Something happened in setting up the request that triggered an Error
      console.log('Error', error.message);
    }

  });

Another approach can be intercepting requests or responses before they are handled by then or catch.

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) {
    // Do something with response data
    return response;
  }, function (error) {
    // Do something with response error
    return Promise.reject(error);
  });

Solution 2:

If you want to gain access to the whole the error body, do it as shown below:

 async function login(reqBody) {
  try {
    let res = await Axios({
      method: 'post',
      url: 'https://myApi.com/path/to/endpoint',
      data: reqBody
    });

    let data = res.data;
    return data;
  } catch (error) {
    console.log(error.response); // this is the main part. Use the response property from the error object

    return error.response;
  }

}

Solution 3:

You can go like this: error.response.data
In my case, I got error property from backend. So, I used error.response.data.error

My code:

axios
  .get(`${API_BASE_URL}/students`)
  .then(response => {
     return response.data
  })
  .then(data => {
     console.log(data)
  })
  .catch(error => {
     console.log(error.response.data.error)
  })

Solution 4:

if u wanna use async await try

export const post = async ( link,data ) => {
const option = {
    method: 'post',
    url: `${URL}${link}`,
    validateStatus: function (status) {
        return status >= 200 && status < 300; // default
      },
    data
};

try {
    const response = await axios(option);
} catch (error) {
    const { response } = error;
    const { request, ...errorObject } = response; // take everything but 'request'
    console.log(errorObject);
}
