    WEBrick is a Ruby library that makes it easy to build an HTTP server with Ruby. 
    It comes with most installations of Ruby by default (it’s part of the standard library),

    The following code creates a generic WEBrick server on the local machine on port 1234,

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
