Add this line to your `Gemfile`:

    gem 'service_it', '~> 1.0.0'

And then execute:

    $ bundle

## Rails Generator

You can use Rails generator to create a `Service`

    $ rails g service NAME

This will create:

```
├── app
    ├── services
        └── name.rb
```

## Usage

```ruby
class Foo < ServiceIt::Base
  def perform
    # put your logic here
    # you can use params that became variables
  end
end
```

Call your service from anywhere

```ruby
Foo.call(foo: foo, bar: bar)
```

    if @post.update(released_at: Date.current)    # <--
      # [...]
    else
      # [...]
    end
  end

  # [...]
