createIteration

IterationRep createIteration(iterationInput)

Create an experiment iteration. Experiment iterations let you record experiments in individual blocks of time. Initially, iterations are created with a status of not_started and appear in the draftIteration field of an experiment. To start or stop an iteration, update the experiment with the startIteration or stopIteration instruction. To learn more, read Start experiment iterations.

Example

import {
    ExperimentsApi,
    Configuration,
    IterationInput
} from 'launchdarkly-api-typescript';

const configuration = new Configuration();
const apiInstance = new ExperimentsApi(configuration);

let projectKey: string; //The project key (default to undefined)
let environmentKey: string; //The environment key (default to undefined)
let experimentKey: string; //The experiment key (default to undefined)

getExperiment

Experiment getExperiment()

Get details about an experiment. ### Expanding the experiment response LaunchDarkly supports four fields for expanding the "Get experiment" response. By default, these fields are not included in the response. To expand the response, append the expand query parameter and add a comma-separated list with any of the following fields: - previousIterations includes all iterations prior to the current iteration. By default only the current iteration is included in the response. - draftIteration includes the iteration which has not been started yet, if any. - secondaryMetrics includes secondary metrics. By default only the primary metric is included in the response. - treatments includes all treatment and parameter details. By default treatment data is not included in the response. For example, expand=draftIteration,treatments includes the draftIteration and treatments fields in the response. If fields that you request with the expand query parameter are empty, they are not included in the response.

Example

import {
    ExperimentsApi,
    Configuration
} from 'launchdarkly-api-typescript';

const configuration = new Configuration();
const apiInstance = new ExperimentsApi(configuration);

let projectKey: string; //The project key (default to undefined)
let environmentKey: string; //The environment key (default to undefined)
let experimentKey: string; //The experiment key (default to undefined)
let expand: string; //A comma-separated list of properties that can reveal additional information in the response. Supported fields are explained above. (optional) (default to undefined)

const { status, data } = await apiInstance.getExperiment(
    projectKey,
    environmentKey,
    experimentKey,
    expand
);

Parameters

Name	Type	Description	Notes
projectKey	[string]	The project key	defaults to undefined
environmentKey	[string]	The environment key	defaults to undefined

getExperiments

ExperimentCollectionRep getExperiments()

Get details about all experiments in an environment. ### Filtering experiments LaunchDarkly supports the filter query param for filtering, with the following fields: - flagKey filters for only experiments that use the flag with the given key. - metricKey filters for only experiments that use the metric with the given key. - status filters for only experiments with an iteration with the given status. An iteration can have the status not_started, running or stopped. For example, filter=flagKey:my-flag,status:running,metricKey:page-load-ms filters for experiments for the given flag key and the given metric key which have a currently running iteration. ### Expanding the experiments response LaunchDarkly supports four fields for expanding the "Get experiments" response. By default, these fields are not included in the response. To expand the response, append the expand query parameter and add a comma-separated list with any of the following fields: - previousIterations includes all iterations prior to the current iteration. By default only the current iteration is included in the response. - draftIteration includes the iteration which has not been started yet, if any. - secondaryMetrics includes secondary metrics. By default only the primary metric is included in the response. - treatments includes all treatment and parameter details. By default treatment data is not included in the response. For example, expand=draftIteration,treatments includes the draftIteration and treatments fields in the response. If fields that you request with the expand query parameter are empty, they are not included in the response.

const configuration = new Configuration();
const apiInstance = new ExperimentsApi(configuration);

let projectKey: string; //The project key (default to undefined)
let environmentKey: string; //The environment key (default to undefined)
let limit: number; //The maximum number of experiments to return. Defaults to 20. (optional) (default to undefined)
let offset: number; //Where to start in the list. Use this with pagination. For example, an offset of 10 skips the first ten items and then returns the next items in the list, up to the query `limit`. (optional) (default to undefined)
let filter: string; //A comma-separated list of filters. Each filter is of the form `field:value`. Supported fields are explained above. (optional) (default to undefined)
let expand: string; //A comma-separated list of properties that can reveal additional information in the response. Supported fields are explained above. (optional) (default to undefined)
let lifecycleState: string; //A comma-separated list of experiment archived states. Supports `archived`, `active`, or both. Defaults to `active` experiments. (optional) (default to undefined)

patchExperiment

Experiment patchExperiment(experimentPatchInput)

Update an experiment. Updating an experiment uses the semantic patch format. To make a semantic patch request, you must append domain-model=launchdarkly.semanticpatch to your Content-Type header. To learn more, read Updates using semantic patch. ### Instructions Semantic patch requests support the following kind instructions for updating experiments. #### updateName Updates the experiment name. ##### Parameters - value: The new name. Here's an example: json { \"instructions\": [{ \"kind\": \"updateName\", \"value\": \"Example updated experiment name\" }] } #### updateDescription Updates the experiment description. ##### Parameters - value: The new description. Here's an example: json { \"instructions\": [{ \"kind\": \"updateDescription\", \"value\": \"Example updated description\" }] } #### startIteration Starts a new iteration for this experiment. You must create a new iteration before calling this instruction. An iteration may not be started until it meets the following criteria: * Its associated flag is toggled on and is not archived * Its randomizationUnit is set * At least one of its treatments has a non-zero allocationPercent ##### Parameters - changeJustification: The reason for starting a new iteration. Required when you call startIteration on an already running experiment, otherwise optional. Here's an example: json { \"instructions\": [{ \"kind\": \"startIteration\", \"changeJustification\": \"It\'s time to start a new iteration\" }] } #### stopIteration Stops the current iteration for this experiment. ##### Parameters - winningTreatmentId: The ID of the winning treatment. Treatment IDs are returned as part of the Get experiment response. They are the _id of each element in the treatments array. - winningReason: The reason for the winner Here's an example: json { \"instructions\": [{ \"kind\": \"stopIteration\", \"winningTreatmentId\": \"3a548ec2-72ac-4e59-8518-5c24f5609ccf\", \"winningReason\": \"Example reason to stop the iteration\" }] } #### archiveExperiment Archives this experiment. Archived experiments are hidden by default in the LaunchDarkly user interface. You cannot start new iterations for archived experiments. Here's an example: json { \"instructions\": [{ \"kind\": \"archiveExperiment\" }] } #### restoreExperiment Restores an archived experiment. After restoring an experiment, you can start new iterations for it again. Here's an example: json { \"instructions\": [{ \"kind\": \"restoreExperiment\" }] }

import {
    ExperimentsApi,
    Configuration,
    ExperimentPatchInput
