Plug into middleware?

[seivan]

How would one go through to plug this into middleware without using the Rails 3 routes?
Because using the routes would put it at th bottom of the stack.
Would save me time from implementing my own dsl... again.

You don't need to use rails3 routes. Grape is a rack application and should be loaded alongside your rails application.

Stick something like this in your config.ru

run Rack::Cascade.new([
   YourAppname::Application,
   YourAppname::API
])

Cool, how would that work with using models and helpers and how would the routes look like?

[benschwarz]

Forget routes!

This is a rack middleware that constructs its own routes using the DSL (much like a sinatra application would).

Perhaps you should create a pretend API outside of your rails application to better understand how middleware works.

Yeah I figured that out. But how would interacting with Rails models, gems and helpers work.
Could it share the Gemfile with a rails application? Could I plug in Devise into it?

[benschwarz]

If you keep it within your rails application, and load it alongside the rails environment (also add it to your config.ru) you'll have access to the core classes (your models).

Devise would just sit over the top—although I'd look into the authenticated examples that are in the sinatra demo app that intridea created for you :)
