Feature Flag Rule

A feature flag rule is part of a feature flag's targeting section. It describes which values shall be returned as a feature flag's evaluation value in case certain conditions are met.

For each feature flag subtype (boolean, number, string) exist separate rule types:

• boolean feature flag: Boolean Feature Flag Rule
• number feature flag: Number Feature Flag Rule
• string feature flag: String Feature Flag Rule

All feature flag rule types share some properties. These shared properties are explained below.

Schema

{
  "enabled": true,
  "conditionSet": { 
    // condition set content 
  },
  
  // subtype specific attributes ...
}

Attributes

enabled

• Type: boolean
• Required

A rule can be turned on/off individually. The following table describes when a rule is evaluated as part of a feature flag evaluation:

featureFlag.targeting.enabled	rule.enabled	Is rule evaluated?
true	true	yes
true	false	no
false	true	no
false	false	no

conditionSet

• Type: ConditionSet
• Required

The rule's condition set describes the conditions to be checked. If the condition set evaluates to true, the rule is seen as a "match", and the valuesOnMatch of the subtypes are used as the feature flag evaluation result/value.
