Add AxiosException class

Is your feature request related to a problem? Please describe. I use typescript. How to verify that I received exactly axios error?

Describe the solution you’d like Add custom error class: AxiosException, which is inherited from the standard Error class

Example

try {
  axios.get('...')
}
catch(err) {
  if (err instanceof AxiosException) {
      console.error(err.response);
  }
}

You can apply type guards with the isAxiosError helper function.

import axios from 'axios';

if (axios.isAxiosError(error)) {
  // error.response?.data ...
}

@ruscon I think you can use type assertion.

import axios, {AxiosError} from 'axios';

try {
  axios.get('...')
}
catch(err) {
  if ((<any>err).isAxiosError) { // check to make sure type assertion is right
      const e = <AxiosError>error;
      console.error(e.response);
  }
}
