This section provides code examples for how You should leveraging the new DecisionDecision and Event TrackingEvent Tracking APIs. All existing Full Stack (Legacy)Full Stack (Legacy) methods and implementation are still supported. See Optimizely Feature Experimentation - application & migrationOptimizely Feature Experimentation - application & migration documentation for the latest updates.

You should adopting the new Decide, Decide All, and Track Event methods as a more flexible and easier-to-use replacement where you currently use isFeatureEnabled, getFeatureVariable, getAllFeatures, or Track calls within your implementation.

The following are examples of how to migrate the Full Stack (Legacy) methods to Feature Experimentation methods:

# -------------------------------
# Prereq for new methods: create a user
# ------------------------------
attributes = {'is_logged_in' => true}
user_id = 'user_123'
user = optimizely_client.create_user_context(user_id, attributes)

# -------------------------------
# Is Feature Enabled
# ------------------------------
# old method
enabled = optimizely_client.is_feature_enabled('price_filter', user_id)

# new method
decision = user.decide('flag_1')
enabled = decision.enabled

# -------------------------------
# Activate & Get Variation
# ------------------------------
# old method
variation_key = optimizely_client.activate('my_experiment_key', user_id, attributes)
# new method
variation_key = decision.variation_key

# -------------------------------
# Get All Feature Variables
# ------------------------------
# old method
all_var_values = optimizely_client.get_all_feature_variables(
  'my_feature_key',
  user_id,
  attributes
)
# new method
all_var_values = decision.variables

# -------------------------------
# Get Enabled Features
# ------------------------------
# old method
enabled_features = optimizely_client.get_enabled_features(user_id, attributes)

# new method
decisions = user.decide_all([Optimizely::Decide::OptimizelyDecideOption::ENABLED_FLAGS_ONLY])
enabled_features = decisions.keys
# -------------------------------
# Track
# ------------------------------
# old method
event_tags = {'purchase_count' => 2}
optimizely_client.track('my_purchase_event_key', user_id, attributes, event_tags)

# new method
user.track_event('my_purchase_event_key', event_tags)
