Worked on stabilizing the HTTP client in the usebruno/bruno repository by addressing a header-handling issue that impacted content negotiation with various servers. Focused on JavaScript and Node.js, the developer delivered a targeted bug fix to ensure the default Accept header in axios was preserved when setting the User-Agent, preventing compatibility issues. The approach involved refactoring header assignment logic to extend existing defaults rather than overwrite them, and comprehensive regression tests were added for both Electron and CLI axios instances. This work improved HTTP client reliability, enhanced interoperability across environments, and demonstrated practical skills in full stack development and testing.
