Tech Debt: Type safety and documentation improvements #154
Description
Summary
During code review of the category deployment optimization (PR #feat/003-rate-limiting-resilience), several pre-existing type safety and documentation issues were identified that should be addressed as tech debt.
Findings
Type Safety Issues in src/core/deployment/stages.ts
| Line | Issue |
|---|---|
| 122 | Type assertion as SaleorConfig used without type guard |
| 264 | Type assertion as ChannelInput used without guard |
| 266-267 | Type assertion as ChannelUpdateInput used multiple times without guard |
| 680 | Double unsafe cast as unknown as ProductAttributeMeta[] |
Suggested Fix: Add proper type guards or validation functions instead of direct type assertions. Consider creating helper functions like isSaleorConfig(), isChannelInput(), etc.
Documentation Pattern in src/lib/utils/bulk-operation-constants.ts
The entire file uses JSDoc comments to document constants. While JSDoc is useful, the project style guide prefers self-documenting code.
Suggested Fix: Evaluate whether to:
- Keep JSDoc (it's standard practice and useful for IDE tooltips)
- Move documentation to a separate docs file
- Rename constants to be more self-documenting
Type Definition Issues
| File | Line | Issue |
|---|---|---|
category-service.ts |
13 | Type alias with & operator creates implicit optional behavior |
repository.ts |
82-84 | Complex type extraction using NonNullable utility |
Suggested Fix: Define explicit interfaces instead of deriving types from query results.
Priority
Low - These are code quality improvements that don't affect functionality.
