In development, I would like to replace localhost:3000 to something like "domain.com:3000" or "domain.com". I can achieve this by adding alias to /etc/hosts file, for ex: 

# /etc/hosts
127.0.0.1   domain.com

^^^ this one works, i can now view my site locally using domain.com.

The problem is that rails itself still uses localhost:3000, for example when generating urls via router methods. I feel that there should be some config for this.

You have to set:

Rails.application.routes.default_url_options[:host] = 'domain.com:3000'

in your development environment.

Custom domain name for your IP Address can be created. First of all find your IP Address using ifconfig. Then open /etc/hosts file with sudo.

/etc/hosts file is in readonly, so need to open with sudo

sudo vi /etc/hosts

There you will find at least two entries for 127.0.0.1 and 127.0.1.1, below this, create your own domain name

<IP_Address> domain.com

Save the file. Then start your rails server and bind with your IP Address.

rails s -b <IP_Address>

And you are done.

In browser, <IP_Address>:3000 will be same as domain.com:3000
