Ladder Summary
- file The module exports a single **default async function `isUp(url)`** that checks whether a given website is reachable. It extracts the hostname from the provided URL, queries the `https://isitup.org/<hostname>.json` API via `got`, throws an error if the API reports an invalid domain, and otherwise returns `true` when the site’s status code indicates it is up (and `false` when it is down).
'use strict';
const got = require('got');
const statusCodes = {
isUp: 1,
isDown: 2,
invalidDomain: 3
};
module.exports = async url => {
- url = new URL(url);
- url = encodeURIComponent(url.host);
+ const hostname = encodeURIComponent((new URL(url)).hostname);
- const {body} = await got(`https://isitup.org/${url}.json`, {
- json: true,
+ const {status_code: statusCode} = await got(`https://isitup.org/${hostname}.json`, {
headers: {
'user-agent': 'https://github.com/sindresorhus/is-up'
}
- });

if (statusCode === statusCodes.invalidDomain) {
