PostCompanyExample.rb

# For a given company id, update the company's location and website 
post '/company' do

  # ... process the request ...

  "id = #{params[:companyId]}, location = #{params[:location]}, website = #{params[:website]}" # echo back the params
end

PostCompanyExample2.rb

post '/company' do

  # Fetch the current member's profile and group data in parallel from two Frontier Content Services
  member, groups = assemble {
    GET resource(:profile, :v0), {:memberId => session[:memberId]}
    GET resource(:group, :v0), {:memberId => session[:memberId]}
  }

  # ... Use member and groups data ...

  "#{member.firstName} is in #{groups.size()} groups"
end

PostCompanyExample3.rb

post '/company' do

  # Fetch the current member's profile and group data in parallel from two Frontier Content Services
  member, groups = assemble {
    GET resource(:profile, :v0), {:memberId => session[:memberId]}
    GET resource(:group, :v0), {:memberId => session[:memberId]}
  }

  # ... Use member and groups data ...


  # Now update the company info
  company = resource(:company, :v0)
  params = {:companyId => params[:companyId], :location => params[:location], :website => params[:website]}

  result = assemble {
    PUT company, params
  }

  "#{member.firstName} just updated the company info for company #{params[:companyId]}"
end

SinatraExample.rb

# Matches www.linkedin.com and prints "Hello World"
get '/' do
  "Hello World"
end

# Matches URLs that start with /hello/ and pulls out a named parameter at the end, 
# e.g. www.linkedin.com/hello/Kevin prints "Hello Kevin"
get '/hello/:name' do |name|
  "Hello #{name}!" 
end

# Matches URLs with a wildcard between hello and world and extracts query/body params, 
# e.g. www.linkedin.com/hello/fooooo/world with a body of {"name": "Jim"} prints "Hello Jim"
post '/hello/*/world' do
  "Hello #{params[:name]}"
end

Thanks for the info, I was just more interested in what the basics of the assemble method looked like behind the scenes. I understand if that is proprietary information, thanks for the info. This is great and I really enjoyed the article. I am working on a very similar application architecture for an app I work on that is JRuby on the front end (we're using Rails) and a bunch of individual Java services on the back end.

It's not really "proprietary" per se, but it does use a lot of internally developed Java libraries so it would be harder to make sense of. You should check out https://github.com/avik-das/asap to see an open-sourced implementation developed here that does something very similar.
