What is a regular service?

  • A regular service is a class with one responsibility - to calculate and return a result of a logical operation. It implements result directly and has no steps.

    class FindUser
  include ConvenientService::Standard::Config

  attr_reader :id

  def initialize(id:)
    @id = id
  end

  def result
    return error("Id is `nil`") if id.nil?

    users = {1 => {name: "John"}}

    return failure("User with id `#{id}` does not exist") unless users.key?(id)

    success(user: users[id])
  end
end

result = FindUser.result(id: 1)

result.success?
# => true

result.data[:user]
# => {name: "John"}

  • A regular service is contrasted with an organizer service, which composes other services via steps instead of implementing the logic directly.
