A MongoDB adapter for Flipper.
Add this line to your application's Gemfile:
gem 'flipper-mongo'
And then execute:
$ bundle
Or install it yourself with:
$ gem install flipper-mongo
In most cases, all you need to do is require the adapter. You must set the MONGO_URL
or FLIPPER_MONGO_URL
environment vairable to specify which Mongo database to connect to.
require 'flipper-mongo`
If you need to customize the adapter, you can add this to an initializer:
Flipper.configure do |config|
config.default do
collection = Mongo::Client.new(ENV["MONGO_URL"])["flipper"]
Flipper.new(Flipper::Adapters::Mongo.new(collection))
end
end
Each feature is stored in a document, which means getting a feature is single query.
require 'flipper/adapters/mongo'
collection = Mongo::Client.new(["127.0.0.1:27017"], database: 'testing')['flipper']
adapter = Flipper::Adapters::Mongo.new(collection)
flipper = Flipper.new(adapter)
# Register a few groups.
Flipper.register(:admins) { |thing| thing.admin? }
Flipper.register(:early_access) { |thing| thing.early_access? }
# Create a user class that has flipper_id instance method.
User = Struct.new(:flipper_id)
flipper[:stats].enable
flipper[:stats].enable_group :admins
flipper[:stats].enable_group :early_access
flipper[:stats].enable_actor User.new('25')
flipper[:stats].enable_actor User.new('90')
flipper[:stats].enable_actor User.new('180')
flipper[:stats].enable_percentage_of_time 15
flipper[:stats].enable_percentage_of_actors 45
flipper[:search].enable
