Optional analyticsUse exposureTrackingProvider instead
Optional automaticIf true, automatically tracks exposure events though the
ExperimentAnalyticsProvider. If no analytics provider is set, this
option does nothing.
Optional automaticThis config only matters if you are using the amplitude analytics SDK
integration initialized by calling
Experiment.initializeWithAmplitudeAnalytics().
If true, the ExperimentClient will automatically fetch variants when the
user's identity changes. The user's identity includes user_id, device_id
and any user properties which are set, unset or clearAlled via a call
to identify().
Note: Non-idempotent identify operations setOnce, add, append, and
prepend are not counted towards the user identity changing.
Optional debugDebug all assignment requests in the UI Debugger and log additional information to the console. This should be false for production builds.
Optional exposureProvides the ability to track exposure events through a 3rd party analytics implementation.
Optional fallbackThe default fallback variant for all variant calls.
Optional fetchExplicitly enable or disable calling fetch() on start():
true: fetch will always be called on start.false: fetch will never be called on start.undefined: fetch will always be called on start.Optional fetchThe request timeout, in milliseconds, when fetching variants.
Optional flagsThe domain to request flag configurations used in local evaluation from.
Optional http(Advanced) Use your own http client.
Optional initialInitial values for flags. This is useful for bootstrapping the client with fallbacks for flag configs.
Optional initialInitial values for variants. This is useful for bootstrapping the client with fallbacks and values evaluated from server-side rendering.
Variants
Optional instanceThe name of the instance being initialized. Used for initializing separate instances of experiment or linking the experiment SDK to a specific instance of the amplitude analytics SDK.
Optional pollEnable or disable local evaluation flag configuration polling on start().
Optional retrySet to true to retry fetch requests in the background if the initial requests fails or times out.
Optional serverThe domain from which to request variants using remote evaluation.
Optional serverThe amplitude data center to fetch flags and variants from. If set, automatically sets the serverUrl and flagsServerUrl configurations.
Optional sourceDetermines the primary source of variants and variants before falling back.
Source
Optional userSets a user provider that will inject identity information into the user for fetch() requests. The user provider will only set user fields in outgoing requests which are null or undefined.
See ExperimentUserProvider for more details
Provides a analytics implementation for standard experiment events generated by the client (e.g. ExposureEvent).
