Developed streaming support for SvelteKit within the inngest/inngest-js repository, focusing on enhancing reliability for long-running workflow steps. The work involved extracting a shared response helper and integrating it with streaming transforms to prevent connection resets, particularly when deployed on Vercel. Refactored URL resolution logic for improved clarity and maintainability, and implemented comprehensive unit and integration tests to validate both explicit and environment-variable-based streaming configurations. Collaborated on documentation updates to ensure cross-repository alignment. Utilized TypeScript and backend development skills throughout, with a strong emphasis on robust unit testing and seamless integration of new features into existing code paths.
