Worked on the prisma/language-tools repository to deliver a configurable diagnostics toggle for the language server, enabling users to control whether diagnostics are displayed through a new enableDiagnostics setting. The implementation involved updating LSSettings to include this boolean option and modifying the validateTextDocument function to respect the setting, ensuring diagnostics are suppressed for the current document when disabled. This feature was developed using TypeScript and required a solid understanding of the Language Server Protocol and configuration management. The work addressed the need for reduced noise and improved performance in diagnostic-heavy workflows, enhancing the overall developer experience and workflow flexibility.
