Global error handling using axios interceptor for http calls http://www.qcode.in/api-error-handling-in-vue-with-axios
Raw
readme.md

How to use it

I am assuming you have a Laravel app with axios installed.

  1. Run npm install izitoast --save to pull the iziToast
  2. Create a resources/assets/js/services folder and place toast.js and errorHandler.js in it.
  3. Now open the resources/assets/js/bootstrap.js and add following:
...
window.axios = require('axios');
window.axios.defaults.headers.common['X-Requested-With'] = 'XMLHttpRequest';

require('./services/errorHandler');
  1. Thats it, now you should be seeing toast notification on request fail.

Turn off gloabl error handling for specific call

You can turn off the global error handling for a specific request by passing {errorHandle: false} as config in axios call.

axios.get('/user/1', {errorHandle: false}).then((response) => {
    console.log('Everything is awesome.');
}).catch((error) => {
    // handle this error here
    console.warn('Not good man :(');
})

errorHandler.js
import axios from 'axios'
import toast from './toast'
function errorResponseHandler(error) {
// check for errorHandle config
if( error.config.hasOwnProperty('errorHandle') && error.config.errorHandle === false ) {
return Promise.reject(error);
}
// if has response show the error
if (error.response) {
toast.error(error.response.data.message);
}
}
// apply interceptor on response
axios.interceptors.response.use(
response => response,
errorResponseHandler
);
export default errorResponseHandler;
Raw
toast.js
import 'izitoast/dist/css/iziToast.min.css'
import iZtoast from 'izitoast'
const toast = {
error: (message, title = 'Error') => {
return iZtoast.error({
title: title,
message: message,
position: 'bottomCenter'
});
},
success: (message, title = 'Success') => {
return iZtoast.success({
title: title,
message: message,
position: 'bottomCenter'
});
}
};
export default toast;

This doesn't seem to work with axios 0.19.x. Any idea how to pass the errorHandle flag in the latest version of axios?

I am using something like this

    // From axios github readme:
    if (error.response) {
      // The request was made and the server responded with a status code
      // that falls out of the range of 2xx
      console.error(error.response.data);
      // toast.error(error.response.data.message); // TODO setup toast notification here
      console.error(error.response.status);
      console.error(error.response.headers);
    } else if (error.request) {
      // The request was made but no response was received
      // `error.request` is an instance of XMLHttpRequest in the browser and an instance of
      // http.ClientRequest in node.js
      console.error(error.request);
    } else {
      // Something happened in setting up the request that triggered an Error
      console.error("Error", error.message);
    }
    console.error("full error object", error);

    // modified from https://gist.github.com/saqueib/a495af17d7c0e2fd5c2316b0822ebac3
    // you can individually handle an error for any ajax call by doing this:
    // axios
    //   .get("/user/1", { handleErrorLocally: true })
    //   .then((response) => console.log("Everything is awesome."))
    //   .catch((error) => {
    //     // handle this error here
    //     console.warn("Not good man :(");
    //   });
    if (
      error.config.hasOwnProperty("handleErrorLocally") &&
      error.config.handleErrorLocally === true
    ) {
      console.error(
        "error.config has handleErrorLocally property, returning error object"
      );
      return Promise.reject(error);
    } else {
      // Throwing in this interceptor may be incorrect behavior in some circumstances,
      // please feel free to change this.
      throw new Error("request failed");
    }

Although I think @Godofbrowser's medium article is pretty great. Typescript is great, but I'm not yet that committed to typescript enough to use interface and class ComposedAjaxError implements ComposedError` although I feel that day is coming soon, I'm holding out for optional static typing to become standardized in ES
