Namespace: client

Client for communicating with Temporal Server.

Most functionality is available through WorkflowClient, but you can also call gRPC methods directly using Connection.workflowService and Connection.operatorService.

Usage​

import { Connection, Client } from '@temporalio/client';
import { loadClientConnectConfig } from '@temporalio/envconfig';
import { sleepForDays } from './workflows';
import { nanoid } from 'nanoid';

async function run() {
  const config = loadClientConnectConfig();
  const connection = await Connection.connect(config.connectionOptions);
  const client = new Client({ connection });

  const handle = await client.workflow.start(sleepForDays, {
    taskQueue: 'sleep-for-days',
    workflowId: 'workflow-' + nanoid(),
  });
  console.log(`Started workflow ${handle.workflowId}`);

  // Wait for workflow completion (runs indefinitely until it receives a signal)
  console.log(await handle.result());
}

run().catch((err) => {
  console.error(err);
  process.exit(1);
});

ScheduleDescription​

Type declaration​

NameTypeDescription
actionScheduleDescriptionActionThe Action that will be taken.
info{ createdAt: Date ; lastUpdatedAt: Date | undefined ; nextActionTimes: Date[] ; numActionsMissedCatchupWindow: number ; numActionsSkippedOverlap: number ; numActionsTaken: number ; recentActions: ScheduleExecutionResult[] ; runningActions: ScheduleExecutionActionResult[] }-
info.createdAtDate-
info.lastUpdatedAtDate | undefined-
info.nextActionTimesDate[]Next upcoming scheduled times of this Schedule
info.numActionsMissedCatchupWindownumberNumber of times a scheduled Action was skipped due to missing the catchup window.
info.numActionsSkippedOverlapnumberNumber of Actions skipped due to overlap.
info.numActionsTakennumberNumber of Actions taken so far.
info.recentActionsScheduleExecutionResult[]Most recent actions started (including manual triggers), sorted from older start time to newer.
info.runningActionsScheduleExecutionActionResult[]Currently-running workflows started by this schedule. (There might be more than one if the overlap policy allows overlaps.)
memo?Record<string, unknown>Additional non-indexed information attached to the Schedule. The values can be anything that is serializable by the DataConverter.
policies{ catchupWindow: number ; overlap: ScheduleOverlapPolicy ; pauseOnFailure: boolean }-
policies.catchupWindownumberThe Temporal Server might be down or unavailable at the time when a Schedule should take an Action. When the Server comes back up, catchupWindow controls which missed Actions should be taken at that point. It takes those Actions according to the ScheduleOverlapPolicy. An outage that lasts longer than the Catchup Window could lead to missed Actions. (But you can always ScheduleHandle.backfill.) Unit is miliseconds.
policies.overlapScheduleOverlapPolicyControls what happens when an Action would be started by a Schedule at the same time that an older Action is still running.
policies.pauseOnFailurebooleanWhen an Action times out or reaches the end of its Retry Policy, pause. With ScheduleOverlapPolicy.ALLOW_ALL, this pause might not apply to the next Action, because the next Action might have already started previous to the failed one finishing. Pausing applies only to Actions that are scheduled to start after the failed one finishes.
scheduleIdstringThe Schedule Id. We recommend using a meaningful business identifier.
searchAttributesSearchAttributesAdditional indexed information attached to the Schedule. More info: https://docs.temporal.io/docs/typescript/search-attributes Values are always converted using JsonPayloadConverter, even when a custom Data Converter is provided. Deprecated Use typedSearchAttributes instead.
specScheduleSpecDescriptionWhen will Actions be taken.
state{ note?: string ; paused: boolean ; remainingActions?: number }-
state.note?stringInformative human-readable message with contextual notes, e.g. the reason a Schedule is paused. The system may overwrite this message on certain conditions, e.g. when pause-on-failure happens.
state.pausedbooleanWhether Schedule is currently paused.
state.remainingActions?numberThe Actions remaining in this Schedule. Once this number hits 0, no further Actions are taken (unless ScheduleHandle.trigger is called). If undefined, then no such limit applies.
typedSearchAttributesTypedSearchAttributesAdditional indexed information attached to the Schedule. More info: https://docs.temporal.io/docs/typescript/search-attributes Values are always converted using JsonPayloadConverter, even when a custom Data Converter is provided.
