Get Client IP Address from HTTP Server Request. How?

[suchislife801]

Using Deno's http server example, each request made returns the following request object about the client.

Where do I get the Client's request IP number from?

Thank you,

Ahhh... ok.

So it's stored in the headers but to obtain it, you must use more than just dot notation.

Example: const clientIPAddress: string = httpRequest.headers.get('host')

It can easily get more complicated than that. For example here is the logic from oak: https://github.com/oakserver/oak/blob/main/request.ts#L40-L59

There is remoteAddr in Deno.Conn

conn.remoteAddr
