Multiple Sinatra apps using rack-mount

I have a question regarding using rack-mount with Sinatra. I've got two classic-style Sinatra apps. Let's call one App defined in app.rb and the other API defined in api.rb.

I would like it so that api.rb handles all routes beginning with '/api' and app.rb ha开发者_开发百科ndles all other requests including the root ('/').

How would I set this up with rack-mount? Or is there a better solution than that?


I think you'll prefer Rack::URLMap - it will probably look something like this:

run Rack::URLMap.new("/" => App.new, 
                     "/api" => Api.new)

That should go in your config.ru file.


I had a similar issue and I am not very familiar with Rack. I could not figure out what to do based on the answers above. My final solution was to have the following in config.ru.

This works perfectly for me.

# Main Ramaze site
map "/" do

    Encoding.default_external = Encoding::UTF_8
    Encoding.default_internal = Encoding::UTF_8

    require ::File.expand_path('../app', __FILE__)

    Ramaze.start(:root => __DIR__, :started => true)
    run Ramaze

end

# Sinatra & Grape API
map "/api" do

    use Rack::Static, :urls => ["/stylesheets", "/images", "/javascripts"], :root => "public"
    use Rack::Session::Cookie

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

end


In config.ru you could also take advantage of Sinatra's middleware feature. If you have several Sinatra apps, each with its own routes, and want to run them simultaneously, you can arrange them in the order you want them found, e.g.

# config.ru
...
use MyAppA
use MyAppB
use MyAppC
run MyAppD


I had the same problem once and so I came up with this template: sinatra-rspec-bundler-template which is layed out for multiple apps.

It may have more features than you need but it should help you when you need something "a bit more" complex.
