Perl Catalyst is an "Elegant MVC Web Application Framework", used by lots of sites.

Catalyst::Controller::REST makes RESTful services easy. (Caveat: learning Catalyst is not trivial.)

Good examples exist to help flatten the learning curve.

Is Mojo mature enough to be used for mission-critical applications or what other framework could you recommend?

Yes, it is mature enough

:) For other recommendations see the "SEE ALSO" or "Comparison" pages on these websites http://www.cgi-app.org, http://www.catalystframework.org/, http://mojolicio.us/

Example REST in Dancer:

get  '/service/items' => sub {
  content_type 'application/json' ;
  my $items = $dbh->selectall_arrayref(...) ;
  return to_json($items) ;
} ;

post '/service/items/:item_id' => sub {
  content_type 'application/json' ;
  $dbh->do(...) ;
  return to_json({updated => 1}) ;
} ;

put  '/service/items' => sub {
  content_type 'application/json' ;
  $dbh->do(...) ;
  return to_json({added => 1}) ;
} ;

del  '/service/items/:item_id' => sub {
  content_type 'application/json' ;
  $dbh->do(...) ;
  return to_json({deleted => 1}) ;
} ;

CGI::Application::Dispatch also provides REST dispatching for the CGI::Application platform.

Hi,

I've got the following problems by using perl for a rest/json api:

1. What framework should I use?
2. Is it usefull to integrate it to apache (Loadbalancing)?
3. Loadbalancing for the REST API ... HOWTO?
4. I want to create an API with special pathes and methods:

I need the following structure (examples):
/user/123 -> lists the user details of user 123
/user/all -> the complete user List
/user/all/10/20 -> the user List beginning at 10 to 20
/user/all/sorted/asc
/user/123/roles -> the roles of user 123

Can anybody help me?
