Export an Activity as an async TypeScript function, type its parameters and return value, and share dependencies through dependency injection.

Call an Activity from a TypeScript Workflow through proxyActivities, set the required Timeout, and keep Activity inputs and results small.

Set the Schedule-To-Close, Start-To-Close, and Heartbeat Timeouts on a TypeScript Activity, tune its Retry Policy, and override the next retry delay.

Implement AI applications in TypeScript using the Temporal TypeScript SDK and the AI SDK.

Asynchronously complete an Activity in Temporal by enabling the Activity Function to return before the Activity Execution finishes, using AsyncCompletionClient.

Mark expected or non-severe Activity errors as benign in TypeScript to reduce noise in logs, metrics, and OpenTelemetry traces.
