Worked on enhancing the gRPC generation workflow in the wundergraph/cosmo repository by introducing support for custom proto lock file paths within the CLI. This involved refactoring file existence checks and improving error handling to provide a smoother user experience and reduce troubleshooting time. The technical approach centered on TypeScript and CLI development, with a focus on aligning path handling logic to accommodate new user options. These updates increased the flexibility and reliability of the gRPC generate command, allowing users to better organize their project structures and maintain their codebases more efficiently without introducing new bugs during the development period.
