LaunchControl
LaunchControl eases and helps improve the integrity of mail delivered via Mandrill templates.
Installation
Add this line to your application's Gemfile:
gem 'launch_control'
And then execute:
$ bundle
Or install it yourself as:
$ gem install launch_control
Within your application (for a Rails app, typically /config/initializers/launch_control.rb), setup your Mandrill API key you wish to use:
LaunchControl.configure do |config|
config.mandrill_api_key = 'your_key_here'
end
Usage
To start using Launch Control, you first need to create a contract class:
class ThankyouEmail < LaunchControl::MandrillContract
def template
'thank-you'
end
def validations
{
first_name: 'string',
last_name: 'string'
}
end
end
Here we define which Mandrill template id we are going to use, and which global merge variables we require to use this template safely. Validations use the Hash Validator gem, check it out for an idea of what's possible.
Now to send an email, we can use our MandrillContract subclass and simply push in all the details required as a hash:
mailer = ThankyouEmail.new
mailer.deliver(to: 'team@lotus.com', subject: 'Bring it home safely', first_name: 'Pastor', last_name: 'Maldonado')
=> true
Now if you try and deliver this without the appropriate content, you'll be pulled up on it:
mailer.deliver(to: 'team@ferarri.com', subject: 'I know what I\'m doing', first_name: 'Kimi')
=> false
mailer.errors
=> {:last_name=>"string required"}
Development
After checking out the repo, run bin/setup
to install dependencies. Then, run rake spec
to run the tests. You can also run bin/console
for an interactive prompt that will allow you to experiment.
To install this gem onto your local machine, run bundle exec rake install
. To release a new version, update the version number in version.rb
, and then run bundle exec rake release
, which will create a git tag for the version, push git commits and tags, and push the .gem
file to rubygems.org.
