Walkthrough

Version control now ignores cursor indexing and specstory directories. Page component adds CDN/page-level caching support through new props and header management utilities, with backward compatibility for legacy cache configurations.

Changes

Cohort / File(s)	Change Summary
Version Control Configuration .gitignore	Added ignore entries for .cursorindexingignore file and .specstory/ directory
Caching Feature website/pages/Page.tsx	Added cacheControl and cacheHeader props to Props interface; introduced CacheHeaderConfig union type and internal CacheHeaderDefault and CacheHeaderCustom interfaces; extended page loader to compute normalized Cache-Control headers and set cache-related headers with legacy compatibility; imported header utilities for cache management

Estimated code review effort

🎯 3 (Moderate) | ⏱️ ~20 minutes

Areas requiring attention:

• Verify backward compatibility logic correctly handles legacy cache configuration shapes (cache object with mode/value, direct strings)
• Validate normalization logic for Cache-Control headers and correct header constant usage
• Confirm device/time variant allowance constraints are properly enforced when caching is enabled
• Review type definitions for CacheHeaderConfig union to ensure completeness

Poem

🐰 Cache Control, oh what a sight,
Headers now dance in page light,
Legacy paths won't cause a fight,
Device variants kept just right,
CDN speeds take their flight! ✨

⚠️ Potential issue | 🔴 Critical

Fix missing exports before merge

The CI run for November 12, 2025 is failing with TS2305 because @deco/deco@1.128.2/utils does not export DECO_PAGE_CACHE_ALLOW_HEADER, DECO_PAGE_CACHE_CONTROL_HEADER, or normalizeCacheControlHeader. Please point these imports at a module that actually exports them (or update the dependency to a version that does) so the project compiles.

In website/pages/Page.tsx around lines 19 to 23, the current import targets
DECO_PAGE_CACHE_ALLOW_HEADER, DECO_PAGE_CACHE_CONTROL_HEADER, and
normalizeCacheControlHeader from "@deco/deco/utils", but that module version
(1.128.2) does not export those symbols; either update the dependency to a
release that exports them or change the import to the module that actually
exports them (e.g., import from the correct path in @deco/deco such as
"@deco/deco/cache" or the module where those names live). Modify the import
statement to reference the correct module, then run the lockfile install
(npm/yarn/pnpm install) and re-run TypeScript to ensure TS2305 is resolved.
