Month: 2026-03 — Summary of developer work on withastro/astro Key features delivered: - Server-Side Rendering (SSR) caching: Added an in-memory LRU cache provider for SSR response caching with configurable rules at the configuration level, plus a no-op path for disabled caches to avoid errors. Integrated into the SSR pipeline so each request creates a per-request AstroCache/NoopAstroCache instance and exposes cache via the render context, enabling faster responses and better cache observability. - Node adapter in-memory LRU cache driver: Implemented a runtime cache provider for @astrojs/node with in-memory LRU, supporting stale-while-revalidate (SWR) background refresh, tag-based and path-based invalidation, and an X-Astro-Cache header for visibility. Auto-activated as the default cache provider when experimental.cache is enabled. - Route caching groundwork: Introduced config-level cache patterns and compiled route matching to determine cache applicability, aligning with the route parsing infrastructure and paving the way for RFC 1245. - API/config improvements and refactors: Renamed cache driver to provider, introduced routeRules under experimental.config, added CacheProvider types, and provided cache.options getter. Enabled safe behavior for disabled caches to avoid runtime errors. Major bugs fixed: - Session management robustness: Prevented data loss on session ID regeneration and mitigated session-fixation risks by rejecting unrecognized IDs; added tests to verify persistence and correctness. - Dev server race condition: Fixed a race in dynamic route parameter resolution under concurrent requests, improving developer experience during local iterations. - Disabled cache stability: Implemented no-op behavior for disabled caches to avoid exceptions in consuming code. Overall impact and accomplishments: - Significantly improved SSR performance and reliability through robust, observable caching (server-side) with per-request lifecycles and clear visibility through headers. - Enhanced developer experience and safety by providing a no-throw disabled-cache path, explicit provider naming, and flexible configuration via routeRules. - Strengthened security around session handling and reduced dev-time flakiness due to race conditions. - Achieved broad test coverage (unit, integration, and node adapter tests) ensuring stability across core caching features and adapters. Technologies/skills demonstrated: - In-memory LRU cache design and integration into SSR lifecycle; routing-pattern based cache applicability; per-request cache contexts; observable cache headers. - Architecture and refactoring: symbol-based internals, cache provider abstraction, and core/runtime separation for better maintenance. - Node adapter development and cross-package caching strategies; SWR-style revalidation and invalidation strategies. - Comprehensive testing, observability, and RFC-driven implementation planning. - Documentation alignment with RFC plan and staged rollout thinking.
