Worked on the langgenius/dify-plugin-daemon repository to enhance endpoint management by implementing cache invalidation when endpoints are enabled or disabled. Developed a dedicated cache invalidation function in Go, focusing on backend development and cache management to ensure data consistency throughout endpoint state transitions. Refactored error handling to improve robustness and traceability, reducing the risk of stale data and making maintenance more straightforward. The approach prioritized reliability and maintainability, addressing potential issues with data coherence across the application. This work leveraged skills in API development and error handling, resulting in a more consistent and reliable backend infrastructure for endpoint lifecycle management.
