Grape stand alone rest api ERROR: No application configured, nothing to run

[Amanda C. Cavallaro]

I have followed this tutorial step by step: https://wildandcrazytutorials.wordpress.com/2016/03/05/how-to-build-a-grape-standalone-rest-api/ 

but I get the error: 

Puma starting in single mode...

Version 3.6.2 (ruby 2.2.2-p95), codename: Sleepy Sunday Serenity

Min threads: 0, max threads: 16

Environment: development

ERROR: No application configured, nothing to run

when I run puma in In ./myapp

I am running it on a MacOs.

I am new to grape and I would love some guidance.

Thank you.

Without reading that tutorial, if you put your app on Github, would be happy to help with a fix.

Hi Daniel,

Thank you for being prompt to help! I've added the project to GitHub: https://github.com/amdcaruso/learning_grape

I would love to get help to have the project up and running so that I can continue following the tutorial and reading other resources to learn and improve: grape.

Other than a syntax error in boot.rb everything worked.

require 'rubygems'

require 'grape'

Dir.glob("**/*.rb").each do |f|

  puts "Loaded #{f}"

  require_relative "../#{f}" unless File.absolute_path(f) == __FILE__

end

Type `rackup` to start the app, that's what reads the config.ru file.

Hppe this helps.

I sincerely appreciate it, Daniel.

It works fine now, I am ready to continue my path in learning grape!
