Worked on enhancing the Sanity Typegen tool within the sanity-io/sanity repository by implementing improved whitespace handling for GROQ query outputs. Focused on code generation and testing using TypeScript, the work involved cleaning unnecessary whitespace from generated queries to produce more consistent and readable output. This change aimed to reduce downstream debugging and errors by ensuring that typegen outputs are both reliable and easy to interpret. Automated tests were added to verify the effectiveness of the whitespace removal, strengthening regression safety and maintaining output quality. The approach emphasized maintainability and reliability in the code generation process for TypeScript projects.
