Developed a centralized utility for parsing body size limits in the sveltejs/kit repository, replacing the previous inline logic with a reusable function written in JavaScript. Focused on backend development and code refactoring, the work included creating a dedicated test suite to ensure the new utility handled various scenarios reliably. Enhanced testing practices by updating ESLint configurations and reactivating a previously disabled smoke test, which was also renamed for clarity. The changes were delivered as a focused, traceable commit, emphasizing maintainability and test hygiene. This approach improved code organization and reliability while streamlining future updates to body size parsing logic.
