5-18: Well-designed Resource struct with minor type preference.The Resource struct is comprehensive and well-structured. All fields have appropriate types and JSON tags.
Consider using
anyinstead ofinterface{}for the Config field to align with Go 1.18+ conventions:- Config map[string]interface{} `json:"config"` + Config map[string]any `json:"config"`
25-31: Consider extracting the payload struct for better reusability.The inline struct for the payload works but could be extracted to improve code organization and potential reusability.
Consider extracting the payload struct:
+type ResourceUpdatePayload struct { + Current Resource `json:"current"` + Previous Resource `json:"previous"` +} + type ResourceUpdatedEvent struct { BaseEvent - Payload struct { - Current Resource `json:"current"` - Previous Resource `json:"previous"` - } + Payload ResourceUpdatePayload `json:"payload"` }

10-16: LGTM! Well-structured base event design.The
BaseEventstruct provides a solid foundation with all necessary metadata fields. The use offloat64for timestamp aligns with common JavaScript/JSON timestamp representations, and the JSON tags are properly configured.
18-21: LGTM! Flexible raw event structure.The
RawEventstruct effectively extendsBaseEventwith a flexible payload usingmap[string]any, which is appropriate for handling arbitrary event data. Theomitemptytag is correctly applied.apps/workspace-engine/pkg/events/resource.go (2)
20-23: LGTM! Clean resource created event structure.The
ResourceCreatedEventfollows the established pattern by embeddingBaseEventand carrying a singleResourcepayload. The design is consistent and appropriate.
33-36: LGTM! Consistent resource deleted event structure.The
ResourceDeletedEventmaintains consistency with theResourceCreatedEventpattern, which is appropriate for the event system design.

8-19: Consider using generics for better type safety and performance.The current implementation uses double JSON encoding/decoding which is inefficient and loses compile-time type safety. Consider using Go generics for a more performant and type-safe approach.
-func parsePayload(payload any, target any) error { - payloadBytes, err := json.Marshal(payload) - if err != nil { - return fmt.Errorf("failed to marshal payload: %w", err) - } - - if err := json.Unmarshal(payloadBytes, target); err != nil { - return fmt.Errorf("failed to unmarshal payload: %w", err) - } - - return nil -} +func parsePayload[T any](payload any, target *T) error { + payloadBytes, err := json.Marshal(payload) + if err != nil { + return fmt.Errorf("failed to marshal payload: %w", err) + } + + if err := json.Unmarshal(payloadBytes, target); err != nil { + return fmt.Errorf("failed to unmarshal payload: %w", err) + } + + return nil +}This approach provides compile-time type safety and makes the target parameter clearly a pointer type.

77-77: Consider reducing log verbosity for large events.Logging the entire
rawEventstructure might be verbose for large payloads. Consider logging only essential fields like event type and ID.- log.Info("Received event", "event", rawEvent) + log.Info("Received event", "type", rawEvent.Type, "timestamp", rawEvent.Timestamp)

50-50: LGTM! Clean integration of the events package.Good approach creating the EventProcessor once and reusing it throughout the consumer lifecycle.
70-71: LGTM! Proper use of the events package types.The switch from local Event struct to events.RawEvent improves code organization and reusability.
79-82: LGTM! Appropriate error handling for event processing.The error handling correctly logs the failure and continues processing the next message, which is the right approach for a message queue consumer.

22-33: Consider adding validation for required BaseEvent fieldsThe event structures are well-designed. However, consider adding a validation method to ensure required fields like
EventType,WorkspaceID, andEventIDare not empty when processing events.Add a validation method:
func (e BaseEvent) Validate() error { if e.EventType == "" { return fmt.Errorf("eventType is required") } if e.WorkspaceID == "" { return fmt.Errorf("workspaceId is required") } if e.EventID == "" { return fmt.Errorf("eventId is required") } return nil }
54-66: Consider adding logging for better observabilityThe message processing logic is correct. Consider adding debug/info logging to track event processing for better observability in production.
Add logging statements:
func (p *MessageReader) ReadMessage(ctx context.Context, msg *kafka.Message) error { var rawEvent RawEvent if err := json.Unmarshal(msg.Value, &rawEvent); err != nil { + p.log.Error("failed to unmarshal event", "error", err) return fmt.Errorf("failed to unmarshal event: %w", err) } + p.log.Debug("processing event", "type", rawEvent.EventType, "eventId", rawEvent.EventID) + handler, ok := p.handlers[rawEvent.EventType] if !ok { + p.log.Warn("unknown event type", "type", rawEvent.EventType) return fmt.Errorf("no handler found for event type: %s", rawEvent.EventType) } - return handler(ctx, rawEvent) + if err := handler(ctx, rawEvent); err != nil { + p.log.Error("handler failed", "type", rawEvent.EventType, "error", err) + return err + } + return nil }

14-20: Event type definitions look good!The
EventTypeand resource event constants are well-defined. The previously missingResourceDeletedconstant has been properly added.
43-52: Constructor implementation looks good!The
NewMessageReaderproperly initializes all handlers and the logger instance. All resource event types are registered with their corresponding handlers.
