How to pass Puma::Configuration to Sinatra?

This is my web app:

class Front < Sinatra::Base
  configure do
    set :server, :puma
  end
  get '/' do
    'Hello, world!'
  end 
end

I start it like this (don't suggest to use Rack, please):

Front.start!

Here is my configuration object for Puma, which I don't know how to pass to it:

require 'puma/configuration'
Puma::Configuration.new({ log_requests: true, debug: true })

Seriously, how?

Configuration is tightly connected to a way in which you run puma server.

The standard way to run puma - puma CLI command. In order to configure puma config file config/puma.rb or config/puma/<environment>.rb should be provided (see example).

But you asked how to pass Puma::Configuration object to puma. I wonder why you need it but AFAIK you need to run puma server programmatically in your application code with Puma::Launcher(see source code)

conf = Puma::Configuration.new do |user_config|
  user_config.threads 1, 10
  user_config.app do |env|
    [200, {}, ["hello world"]]
  end
 end
Puma::Launcher.new(conf, events: Puma::Events.stdio).run

user_config.app may be any callable object (compatible with Rack interface) like Sinatra application.

Hope it's helpful.

Do you want to pass exactly an object or just a configuration in general? For the last option it's possible, but Puma will not log anything anyway (I'm not sure, but seems like you worry exactly about logging settings for Puma).

#!/usr/bin/env ruby

# frozen_string_literal: true

require 'bundler/inline'

gemfile(true) do
  gem 'sinatra'
  gem 'puma'
  gem 'openssl'
end

require 'sinatra/base'

class Front < Sinatra::Base
  configure do
    set :server, :puma
    set :server_settings, log_requests: true, debug: true, environment: 'foo'
  end

  get '/' do
    'Hello, world!'
  end
end

Front.start!
