Class: UpgradeClient

UpgradeClient.UpgradeClient

UpGradeClient is the main class for interacting with the UpGrade API.

Example

import UpgradeClient from 'upgrade_client_lib/dist/browser';
import UpgradeClient from 'upgrade_client_lib/dist/node';

General UpGrade types can also be accessed as named exports:

import UpgradeClient, { IExperimentAssignment } from 'upgrade_client_lib/dist/browser';

SDK-Specific types can be accessed also:

import { Interfaces } from 'upgrade_client_lib/dist/clientlibs/js/src/identifiers';

const initResponse: Interfaces.IUser = await upgradeClient.init();

Constructors

constructor

• new UpgradeClient(userId, hostUrl, context, options?)

When constructing UpgradeClient, the user id, api host url, and "context" identifier are required. These will be attached to various API calls for this instance of the client.

Example

// required
const hostUrl: "htts://my-hosted-upgrade-api.com";
const userId: "abc123";
const context: "my-app-context-name";

// not required, each is also optional
const options: {
  token: "someToken";
  clientSessionId: "someSessionId";
}

const upgradeClient: UpgradeClient[] = new UpgradeClient(hostURL, userId, context);
const upgradeClient: UpgradeClient[] = new UpgradeClient(hostURL, userId, context, options);

Methods

getAllExperimentConditions

▸ getAllExperimentConditions(): Promise<IExperimentAssignmentv5[]>

Will return all the experiment conditions for the user. Internally this uses the context and userId to query conditions for all eligible decision points at enrolling experiments for this user.

Example

const allExperimentConditionsResponse: IExperimentAssignmentv5[] = await upgradeClient.getAllExperimentConditions(workingGroup);

Returns

Promise<IExperimentAssignmentv5[]>

Defined in

UpgradeClient.ts:237

getDecisionPointAssignment

▸ getDecisionPointAssignment(site, target?): Promise<Assignment>

Given a site and optional target, return the condition assignment at this decision point NOTE: If getAllExperimentConditions() has not been called, this will call it first. NOTE ALSO: If getAllExperimentConditions() has been called, this will return the cached result and not make a network call.

Example

const allExperimentConditionsResponse: IExperimentAssignmentv5[] = await upgradeClient.getDecisionPointAssignment(workingGroup);

Parameters

Name
Type

site

string

target?

string

Returns

Promise<Assignment>

Defined in

UpgradeClient.ts:263

init

▸ init(group?, workingGroup?): Promise<IUser>

This will initialize user and metadata for the user. It will return the user object with id, group, and working group. NOTE: A user must be initialized at least once before calling any other methods. Else, you will see "Experiment user not defined" errors when other SDK methods are called.

Example

const group: Record<string, Array<string>> = {
  classId: ['class1', 'class2'],
  districtId: ['district1', 'district2'],
}

const workingGroup: Record<string, string> = {
 classId: 'class1',
 districtId: 'district2',
}

const initResponse: Interfaces.IUser[] = await upgradeClient.init();
const initResponse: Interfaces.IUser[] = await upgradeClient.init(group);
const initResponse: Interfaces.IUser[] = await upgradeClient.init(group, workingGroup);

Parameters

Name
Type

group?

Record<string, string[]>

workingGroup?

const logRequest: CaliperEnvelope = {
     sensor: 'test',
     sendTime: 'test',
     dataVersion: 'test',
     data: [],
   };

markExperimentPoint

▸ markExperimentPoint(site, condition?, status, target?, uniquifier?,clientError?): Promise<IMarkExperimentPoint>

Will record ("mark") that a user has "seen" a decision point.

Marking the decision point will record the user's condition assignment and the time of the decision point, regardless of whether the user is enrolled in an experiment.

status signifies a client application's note on what it did in the code with condition assignment that Upgrade provided. Status can be one of the following:

export enum MARKED_DECISION_POINT_STATUS {
  CONDITION_APPLIED = 'condition applied',
  CONDITION_FAILED_TO_APPLY = 'condition not applied',
  NO_CONDITION_ASSIGNED = 'no condition assigned',
}

The client can also send along an additional clientError string to log context as to why a condition was not applied.

Example

import { MARKED_DECISION_POINT_STATUS } from 'upgrade_types';

const site = 'dashboard';
const condition = 'variant_x'; // send null if no condition / no experiment is running / error
const status: MARKED_DECISION_POINT_STATUS = MARKED_DECISION_POINT_STATUS.CONDITION_FAILED_TO_APPLY
const target = 'experimental button'; // optional
const clientError = 'variant not recognized'; //optional

const allExperimentConditionsResponse: IExperimentAssignmentv4[] = await upgradeClient.markExperimentPoint(site, condition, MARKED_DECISION_POINT_STATUS.CONDITION_APPLIED, target, clientError);
