# Monadix

Simple result objects in Ruby.

## Installation

Install the gem and add to the application's Gemfile by executing:

    $ bundle add monadix

If bundler is not being used to manage dependencies, install the gem by executing:

    $ gem install monadix

## Usage

```ruby

# file app/lib

# It's a good practice to not expose inner gems to the rest of the app

# so we wrap it.

module Result

  class Success < Monadix::Success; end

  class Failure < Monadix::Success; end

end

class SomeService

  G_OAUTH = lambda do |cmd|

    payload = Google::Auth::IDTokens.verify_oidc(cmd.jwt, aud: ENV.fetch("GOOGLE_OAUTH_CLIENT_ID"))

    info =  UserInfo.new(email: payload[:email], name: payload[:name])

    Result::Success.new(info)

  end

  CreateUser = lambda do |res|

    res.then do |info|

      user = UserFactory.create(info)

      user.save && Result::Success.new(LoginToken.new(user)) || 

        Result::Failure.new("User cannot be created", user.errors.full_messages)

    end

  end

  

  def call(cmd)

    steps.reduce(cmd) { |memo, step| step.call(memo) }

  end

  

  private

  

  def steps

    [

      G_AUTH,

      CreateUser

    ]

  end

end

# Some controller

class AuthCallbacksControler

  def google_oauth2

    cmd = GoogleSignInCommand.new(jwt: params.require(:credential))

    res = SomeService.new.call(cmd)

    if res.success?

      render json: res.data

    else

      render json: res.data, status: :bad_request

    end

  end

end

```
