From 58d33333c617ac258a28dbbe31d5febee426cbac Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Wed, 4 Feb 2026 16:23:40 +0000 Subject: [PATCH 1/5] feat: improve type safety in leaf node utility modules This commit improves type safety in `src/utils/dot-env.ts` and `src/utils/deploy/upload-files.ts` by: - Defining clear interfaces for data structures (`DotEnvFile`, `UploadFileObj`, etc.). - Adding explicit types to function parameters and return values. - Implementing robust type guards (e.g., `isErrorWithStatus`) for safe error handling. - Removing numerous `@ts-expect-error` and implicit `any` types. - Updating corresponding unit tests to match stricter types. - Resolving downstream type errors in `src/utils/dev.ts`. These changes follow modern TypeScript best practices and improve maintainability by documenting the contract between utility functions and their consumers.
