During December 2024, contributed to the withastro/astro repository by addressing a targeted reliability issue in RSS feed delivery. Focused on backend and API development using JavaScript and TypeScript, the work involved normalizing the RSS Content-Type header to the standard 'application/rss+xml' with UTF-8 charset. This technical adjustment ensured proper encoding and improved compatibility across a wide range of RSS readers and clients. The patch was integrated into the @astrojs/rss package, with updates to the changeset for improved traceability. Validation included cross-client testing to confirm reduced parsing issues, supporting downstream consumers and enhancing the robustness of RSS integrations.
