- Removed unnecessary import of `MessageEvent` from `@nestjs/common` in `realtime.types.ts`. - Updated `realtime.pubsub.ts` to import `OnModuleDestroy` and `OnModuleInit` as types, improving clarity and consistency in type usage. - Added a note in `realtime.types.ts` to clarify the non-generic nature of `MessageEvent` in the current setup, ensuring better understanding of shared type definitions.
