This file can be used to boot your project from external commands. For instance to use it with Sidekiq.

config/environment.rb

require 'bundler/setup'
require 'hanami/setup'
require 'hanami/model'
require_relative '../lib/bookshelf'
require_relative '../apps/web/application'
Hanami.configure do
  mount Web::Application, at: '/'
  model do
    adapter :sql, ENV['DATABASE_URL']
    migrations 'db/migrations'
    schema     'db/schema.sql'
  end
  mailer do
    # Make sure this folder exists, or delete this row.
    root Hanami.root.join("lib", "bookshelf", "mailers")
    # This has changed. It used to be a block, now it's a setting
    delivery :test
  end
  # These two blocks are new.
  # They MUST be after the general settings like `mount`, `model`, `mailer`.
  environment :development do
    # See: http://guides.hanamirb.org/projects/logging/
    logger level: :info
  end
  environment :production do
    logger level: :info, formatter: :json
