JS redirect to provided http url and possibly open native app.

Imagine you want to redirect user to https://vk.com/buzovaofficial, but if possible open it in native VK app.

1. Get corresponding deeplink urls from here: https://app.urlgeni.us/

• ios: vk://vk.com/buzovaofficial
• android: intent://vk.com/buzovaofficial#Intent;package=com.vkontakte.android;scheme=vkontakte;end

2. Build redirector url:

   const url = 'https://vitalets.github.io/redirector' +
    '?web=' + encodeURIComponent('https://vk.com/buzovaofficial') +
    '&ios=' + encodeURIComponent('vk://vk.com/buzovaofficial') +
    '&android=' + encodeURIComponent('intent://vk.com/buzovaofficial#Intent;package=com.vkontakte.android;scheme=vkontakte;end');

   Result:

   https://vitalets.github.io/redirector?web=https%3A%2F%2Fvk.com%2Fbuzovaofficial&ios=vk%3A%2F%2Fvk.com%2Fbuzovaofficial&android=intent%3A%2F%2Fvk.com%2Fbuzovaofficial%23Intent%3Bpackage%3Dcom.vkontakte.android%3Bscheme%3Dvkontakte%3Bend
   

3. Open this link on ios, android or desktop
