Axios Interceptor to delay and retry original request for certain status code (polling)

gistfile1.txt

import axios from 'axios';

const instance = axios.create({
    baseURL: 'http://localhost:5000'
});

const sleepRequest = (milliseconds, originalRequest) => {
    return new Promise((resolve, reject) => {
        setTimeout(() => resolve(instance(originalRequest)), milliseconds);
    });
};

instance.interceptors.response.use(response => {
    return response;
}, error => {
    const { config, response: { status }} = error;
    const originalRequest = config;

    if (status === 420) {
        return sleepRequest(1000, originalRequest);
    } else {
        return Promise.reject(error);
    }
});

export default instance;
