@nodifier/errvo

Utils for handling error coming from http requests/responses

How to use?

You can import the module to your code as follows:

import { HttpError } from "@nodify/errvo";

Throwing http request error

throw new HttpError(error);

Expected output from the thrown object would be the same as the standard Error object with some preconfigured value tailored to http request errors.

It will also logs the error with the error log level.

• InternalServerError
• BadGatewayError
• TimeoutError
• OtherError

Supports

1. Native NodeJS http/https request
2. Axios request module

NodeJS native http/https

import http from 'http';
import { HttpError } from '@nodifier/errvo';

const options: http.RequestOptions = {
hostname: 'api.example.com',
port: 443,
path: '/users',
method: 'POST',
headers: {
'Content-Type': 'application/json',
'Authorization': 'Bearer your_token' // Replace with your actual token
}
};

const postData = JSON.stringify({
name: 'John Doe',
email: '[email address removed]'
});

const req = http.request(options, (res) => {
    res.on('error', (error) => {
        /**
         * Throwing a http response error and logging it
         * 
        */
        throw new HttpError(error);
    });

/**

*/
req.on('error', (error) => {
 throw new HttpError(error);
});

req.write(postData);

import axios from 'axios';
import { HttpError } from '@nodifier/errvo';

axios
    .request(options)
    .then((response) => {
        if(response.status && response.status >= 400) {
            throw new HttpError(response);
        }
    })
    .catch((error) => {
