Worked on enhancing code generation and GROQ parsing capabilities within the sanity-io/sanity and sanity-io/groq-js repositories. Focused on enabling export * syntax for TypeScript imports in the codegen tool, improving the handling of literal function arguments and default values in GROQ template parsing, and expanding test coverage to ensure reliability. Addressed a parser issue in groq-js by correcting the handling of PipeFuncCall within projections, preserving GROQ query semantics. Utilized JavaScript, TypeScript, and AST parsing techniques to deliver these improvements, which streamline dynamic query construction and reduce runtime surprises for developers working with Sanity’s platform and GROQ queries.
