Developed and integrated a real-time event streaming feature in the IndexController of the hectorqin/hyperf repository, enabling clients to receive immediate HTTP data updates. Focused on backend development using PHP, the work leveraged event-driven programming to deliver low-latency data delivery without disrupting the existing request and response flow. The implementation included comprehensive documentation and commit traceability, supporting both onboarding and future scalability. By enhancing HTTP streaming capabilities, the changes provided tangible business value through more interactive client experiences. The approach emphasized maintainability and clear change visibility, ensuring that the new feature could be easily adopted and extended as requirements evolved.
