Properties

client

• Readonly client: WorkflowClient

Readonly accessor to the underlying WorkflowClient

Inherited from

WorkflowHandle.client

---

firstExecutionRunId

• Readonly firstExecutionRunId: string

Run Id of the first Execution in the Workflow Execution Chain.

Methods

cancel

▸ cancel(): Promise<IRequestCancelWorkflowExecutionResponse>

Cancel a running Workflow.

When a Workflow is cancelled, the root scope throws CancelledFailure with message: 'Workflow canceled'. That means that all cancellable scopes will throw CancelledFailure.

Cancellation may be propagated to Activities depending on ActivityOptions#cancellationType, after which Activity calls may throw an ActivityFailure, and isCancellation(error) will be true (see isCancellation).

Cancellation may be propagated to Child Workflows depending on ChildWorkflowOptions#cancellationType, after which calls to executeChild and ChildWorkflowHandle#result will throw, and isCancellation(error) will be true (see isCancellation).

Returns

Promise<IRequestCancelWorkflowExecutionResponse>

Inherited from

WorkflowHandle.cancel

describe

▸ describe(): Promise<WorkflowExecutionDescription>

Describe the current workflow execution

Returns

Promise<WorkflowExecutionDescription>

Inherited from

executeUpdate

▸ executeUpdate<Ret, Args, Name>(def, options): Promise<Ret>

Start an Update and wait for the result.

Type parameters

Name	Type
Ret	Ret
Args	extends [any, ...any[]]
Name	extends string = string

Parameters

Name	Type	Description
def	string | UpdateDefinition<Ret, Args, Name>	an Update definition as returned from defineUpdate
options	WorkflowUpdateOptions & { args: Args }	Update arguments

Returns

Promise<Ret>

Throws

WorkflowUpdateFailedError if Update validation fails or if ApplicationFailure is thrown in the Update handler.

startUpdate

▸ startUpdate<Ret, Args, Name>(def, options): Promise<WorkflowUpdateHandle<Ret>>

Returns

Promise<WorkflowUpdateHandle<Ret>>

Throws

WorkflowUpdateFailedError if Update validation fails.

Throws

WorkflowUpdateRPCTimeoutOrCancelledError if this Update call timed out or was cancelled. This doesn't mean the update itself was timed out or cancelled.
