Add AxiosException class

BC?: no

Does anyone know if this is going to move forward ?

It would be really nice to be able to do a

instanceof 

... check in typesript

For now, we use this:

import { AxiosError, AxiosInstance, AxiosRequestConfig, AxiosResponse, default as Axios } from 'axios';

export class AxiosException<T = any> extends Error implements AxiosError {
    config: AxiosRequestConfig;
    code?: string;
    request?: any;
    response?: AxiosResponse<T>;
    isAxiosError: boolean;

    constructor(error: Partial<AxiosError>) {
        const responseMessage: string = error.response && error.response.data ? `Response: ${JSON.stringify(error.response.data)}` : '';
        const errorMessage: string = responseMessage ? `${error.message} ${responseMessage}` : error.message || '';

        super(errorMessage);

        Object.assign(this, error);
        this.message = errorMessage;

        this.name = error.constructor.name;
        this.code = error.code;

        if (Error.captureStackTrace) {
            Error.captureStackTrace(this, AxiosException);
        }
    }
}

export function createAxiosInstance(config: AxiosRequestConfig = {}): AxiosInstance {
    Axios.defaults.timeout = 15000;
    const axios: AxiosInstance = Axios.create(config);

    // Convert axios error object to AxiosException class
    axios.interceptors.response.use(
        (response: AxiosResponse) => {
            return response;
        },
        async (error: any) => {
            return Promise.reject(new AxiosException(error));
        },
    );

    return axios;
}
