refactor(nexus): replace hand-rolled standalone nexus operation types with @temporalio/proto by rossedfort · Pull Request #3646 · temporalio/ui

rossedfort · 2026-07-08T20:33:25Z

Description & motivation 💭

Replaces the fully hand-written standalone nexus operation type definitions with interfaces that extend proto types from @temporalio/proto, following the same pattern already used by activity-execution.ts.

Previously, NexusOperationExecutionInfo, NexusOperationExecutionListInfo, NexusOperationExecutionCancellationInfo, and NexusOperationExecution were standalone interfaces that duplicated proto field names and types manually. Any new field added to the proto would be silently missing from the UI. Now they use extends Omit<ProtoType, overridden-fields> so all proto fields are inherited automatically, and only the fields that need UI-friendly types (timestamps as string, durations as string, enums as named string unions, search attributes as WorkflowSearchAttributes) are re-declared.

StartNexusOperationExecutionRequest omitted every one of its proto fields and redefined them all — making the extends redundant. It is now a plain interface (StartNexusOperationRequest) wrapping only the UI-specific overrides (timeout/policy fields as strings).

NexusOperationIdReusePolicy, NexusOperationIdConflictPolicy, and NexusOperationCancellationState are derived from the proto enums at runtime via Object.keys(temporal.api.enums.v1.*) and re-exported from types/index.ts so consumers import from the canonical location.

Docs

Any docs updates needed?

No docs changes needed — purely internal type refactor.

Migrate standalone nexus operation types to extend proto interfaces instead of duplicating field definitions. NexusOperationExecutionInfo, NexusOperationExecutionListInfo, NexusOperationExecutionCancellationInfo, and NexusOperationExecution now use extends Omit<ProtoType, ...> so proto fields are inherited directly. Enum-derived types and policy arrays are sourced from the proto enums at runtime. StartNexusOperationExecutionRequest was a plain re-definition with no inherited proto fields, so it stays as a plain interface (renamed StartNexusOperationRequest) wrapping the proto request type. NexusOperationIdReusePolicy, NexusOperationIdConflictPolicy, and NexusOperationCancellationState are re-exported from types/index.ts.
