UpgradeClient named class is exported from this library

This is a static method to set host URL which can be accessed by
UpgradeClient.setHostUrl(url)

Two ways for initializing users const upClient = UpgradeClient('userId'); const upClient = UpgradeClient('userId', 'token');

Set alternative user ids for current user
upClient.setAltUserIds(altUserIds)

Updates/Set the group membership of the initialized user
upClient.setGroupMembership(group)

Updates/Set the working group of the initialized user
upClient.setWorkingGroup(workingGroup)

Get all the experiment assignments for the initialized user
upClient.getAllExperimentConditions(context)

Returns the Experiment Condition for the partition and point received from the getAllExperimentConditions for the initialized user
upClient.getExperimentCondition(experimentPoint)
upClient.getExperimentCondition(experimentPoint, partitionId)

Calls markExperimentPoint for experiment point and partitionId. It will use the user definition from initialized user
upClient.markExperimentPoint(experimentPoint)
upClient.markExperimentPoint(experimentPoint, partitionId)

Use this function to report failure with given reason
upClient.failedExperimentPoint(experimentPoint, reason)
upClient.failedExperimentPoint(experimentPoint, reason, experimentId)

Use this function to log data

interface ILogMetrics {
  attributes: any;
  groupedMetrics: ILogGroupMetrics[];
}

interface ILogGroupMetrics {
  groupClass: string;
  groupKey: string;
  groupUniquifier: string;
  attributes: any;
}

interface ILogInput {
  timestamp: string;
  metrics: ILogMetrics;
}
upClient.log(value)

Use this function to add metrics in upgrade system

interface IGroupMetric {
    groupClass: string;
    allowedKeys: string[];
    attributes: Array<IGroupMetric | ISingleMetric>;
}
interface ISingleMetric {
    metric: string;
    datatype: IMetricMetaData;
    allowedValues?: Array<string | number>;
}
enum IMetricMetaData {
  CONTINUOUS = 'continuous',
  CATEGORICAL = 'categorical'
}
upClient.addMetrics(metrics)

Use this function to get feature flags list
upClient.getAllFeatureFlags()

Use this function to get feature flag matched to given key upClient.getFeatureFlag(key)
