Ruby web service with REST support

addis_a · July 5, 2013, 11:50am

Hi All,

I want to develop the webservice in Ruby that will support the REST API
calls.
Can anybody please suggest how to write such a service?

Regards,
Shubhada

I would suggest you install the Sinatra gem, and read the
documentation attached to it. http://www.sinatrarb.com/

Alternatively Webrick which is part of the standard library can be used
to
create HTTP services (including REST) more manually.

Kind regards

Are there any limitations with Webrick? or we can use it for any kind of
REST API request?
Is there any good tutorial for Webrick usage?

Webrick is build in easy to use application server.

I read on the web, Webrick is good for development but not for
production. It has some known memory issues and HTTP parsing problems
also. So,

Is there any alternate for this?
How we can integrate it with Tomcat Apache?

Webrick (I am not sure about it… but I guess this would be required

phusion passenger OR JRuby OR Sinatra (This is also I am not sure

Can anybody help me out to figure it out? Is more explanation is
required to understand the problem?

If you use Sinatra or Webrick there really seems to be no point in
having
Tomcat in between. That just gives you one more step with latency. If
your application is running on JRuby the situation is different: you may
be
able to have JRuby and Tomcat run in the same JVM and communicate via
function / method calls.

Hi,
Basically we want to make our application to be supported with REST
APIs.
We will receive the REST requests to Tomcat application server. And from
there we need to forward it to our application in ruby.

So I want to understand that what the exact things I will need to have
to complete this setup for REST communication. Few things I have listed
down.

The application
Tomcat apache server
Webrick (I am not sure about it… but I guess this would be required
to serve the REST requests.)
phusion passenger OR JRuby OR Sinatra (This is also I am not sure
about. But, for communication between Tomcat and our framework in ruby.)

Can anybody help me out to figure it out? Is more explanation is
required to understand the problem?

I’m going to go out on a limb and make a crazy suggestion: Rails

shubhada_s · July 9, 2013, 7:41pm

Thanks Robert.

It is sure that there is Tomcat server. So I will not use Sinatra or
Webrick. Also my application is pure Ruby based application.

So what is preferable in this case?

Also, when phusion passenger is used?

Shubhada

Do u mean tomcat Apache+ rails+ ruby?

Can be rails integrated with tomcat?

+1 for Rails.

With jRuby, yes, tomcat (or any container) should work fine. Check out
warbler.

They’re orthogonal. Phusion Passenger is an Apache/nginx module which
manages Ruby web applications in a somewhat framework-agnostic manner.

Rails is a framework for building web applications. You can use Phusion
Passenger to serve Rails applications from Apache/nginx.

Hi,
Thank you all for your inputs.

I have a different track now. What is difference between CGI based web
applications and phusion passenger/ sinatra based web applications?

What could be the best option for REST implementation?

Shubhada
