Do you think we are missing an alternative of can_use or a related project?
🤔Can I use this feature? Hmm, let me see.
CanUse is a minimalist feature toggle/flag for crystal, based on yaml file.
- Add the dependency to your
dependencies: can_use: github: rodrigopinto/can_use
- Require the library on your code base.
Create a file with the features toggle definitions. We suggest to name it as
featutes.yaml, but it is up to you.
defaultsblock is mandatory, as it will be used as fallback when values are not defined on the environment set on
defaults: new_payment_flow: false rating_service: false development: new_payment_flow: true rating_service: false your_environment: new_payment_flow: true
- Configure the environment and the path to the yaml.
CanUse.configure do |config| config.file = "path/to/features.yaml" config.environment = "your_environment" end
- Verify if a feature is toggled on/off
if CanUse.feature?("new_payment_flow") # do_something end
- Enabling or Disabling a feature is simple as
CanUse.feature?("feature_a") # => false CanUse.enable("feature_a") # => true CanUse.feature?("feature_a") # => true
CanUse.feature?("feature_b") # => true CanUse.disable("feature_b") # => false CanUse.feature?("feature_b") # => false
