I can't understand one thing- does NodeJS allow to listen to custom hostname? Not localhost. Because when I listen to my website url (example.com), I'm getting the following error:

Error: listen EADDRNOTAVAIL example.com ip-address:1000 at Object.exports._errnoException (util.js:1022:11) at exports._exceptionWithHostPort (util.js:1045:20) at Server._listen2 (net.js:1246:19) at listen (net.js:1295:10) at net.js:1405:9 at _combinedTickCallback (internal/process/next_tick.js:77:11) at process._tickCallback (internal/process/next_tick.js:98:9) at Module.runMain (module.js:606:11) at run (bootstrap_node.js:394:7) at startup (bootstrap_node.js:149:9)

Why does it happend? And can I listen for POST messages from external site URL?

If example.com resolves to the IP of the machine you are running this server, then you should be able to listen on example.com. Please check which address example.com resolves to in your case. – volatilevar
It isn't. Ip of example.com and Ip of my machine are different. So there is no way to listen to example.com from my local machine? – user7248306
then no. You can only listen to an address (or a domain name pointing to an address) that is on your machine. – volatilevar
you only needed this for your local testing ? – Renjith Thankachan

Why does it happend?

This happens because the hostname and port you requested isn't available to you.

can I listen for POST messages from external site URL?

No, You can't. server.listen() accepts hostname and port

Begin accepting connections on the specified port and hostname. If the hostname is omitted, the server will accept connections on any IPv6 address (::) when IPv6 is available, or any IPv4 address (0.0.0.0) otherwise. Omit the port argument, or use a port value of 0, to have the operating system assign a random port, which can be retrieved by using server.address().port after the 'listening' event has been emitted.

And further digging into list of Node.js Common System Errors docs and exhaustive list, It is clear that, Address not available was the case.

EADDRNOTAVAIL Address not available (POSIX.1).
