url-exists-deep

A deeper node library to determine if a url exists.

url-exists-deep was developed for performance and accuracy. To check whether a url exists or not a HEAD request is sent, because this is much faster then a GET. Most hosts are responding correct. If the host responses with a 403 Forbidden a GET request with User-Agent and Accept header is sent.

Usage

var urlExists = require('url-exists-deep');
var url = 'https://www.google.com';
urlExists(url)
  .then(function(response){
    if (response) {
      console.log("Url exists", response.href);
    } else {
      console.log("Url does not exists!");
    }
  });

Makes a deeper determination if a url exists or not. To reduce false negative responses.

Rewrites 301

If url redirects with 301 url-exists-deep follows the redirect and returns the destination url if exists.
