Worked on improving the reliability and data integrity of streaming chat flows in the chatboxai/chatbox repository, focusing on front-end development and API integration using TypeScript. Addressed a persistent issue where long streaming sessions resulted in garbled Chinese characters by reusing a single TextDecoder instance throughout the entire streaming lifecycle. This technical approach resolved character encoding problems that previously arose when a new decoder was created for each data chunk. The solution enhanced real-time chat stability, reduced user-facing errors, and improved maintainability for non-ASCII content. No new features were shipped, with efforts concentrated on foundational bug fixes and code quality improvements.
