📝 Walkthrough

Walkthrough

The change centralizes cache configuration, adds total byte budgets, initializes the global fetch cache with configured limits, normalizes module-loader settings, removes image-specific cache-size configuration, and filters tracking parameters from cache keys.

Changes

Cache configuration and runtime integration

Layer / File(s) Summary
Cache budget contracts and parsing
crates/rari/src/server/config.rs, crates/rari/src/runtime/module_loader/config.rs, packages/rari/src/vite/server/config.ts
Cache configuration now supports maxBytes, per-layer limits, updated module and fetch defaults, budget distribution, and normalized runtime conversion.
Module loader cache mapping
crates/rari/src/runtime/module_loader/config.rs, crates/rari/src/runtime/module_loader/core.rs, crates/rari/src/runtime/module_loader/stubs/rari.rs
RariModuleLoader loads global cache settings through RuntimeConfig and converts them into cache-layer configuration. The image cache-size stub export was removed.
Server cache initialization and image cache cleanup
crates/rari/src/server/core/mod.rs, crates/rari/src/server/image/*, packages/rari/src/vite/index.ts
Server startup initializes and reports cache budgets. Image caching uses a fixed 100 MiB default. The image-specific maxCacheSize option and exports were removed.
Configurable global fetch cache
crates/rari/src/server/middleware/request_context.rs
The global fetch cache uses configurable byte limits, rejects oversized entries, and evicts least-recently-used entries when required.
Cache-key query filtering
crates/rari/src/server/routing/app.rs
Tracking and attribution query parameters are removed from cache keys and render inputs. Functional parameters remain.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: ⚪ Minimal · up to ebb7b

The configuration changes are merge-ready after normal checks and review, with no actionable merge-blocking risk remaining.

Poem

A rabbit tuned the cache with care,
Byte limits hop through every layer.
Tracking tags now fade from sight,
Fresh fetches fit the budget right.
Module paths and images share,
A tidy cache in springtime air.

Inline comments:
In `@crates/rari/src/server/config.rs`:
- Around line 184-192: Update the byte-budget calculation around
layer_participates_in_byte_budget so the fetch layer is included regardless of
its configured handler, matching GlobalFetchCache initialization in the server
core. Ensure fetch.max_bytes receives its proportional allocation when
cache.maxBytes is set, and add coverage for a non-memory fetch handler.

In `@crates/rari/src/server/middleware/request_context.rs`:
- Around line 102-116: Update init_global_fetch_cache so configured limits
cannot be silently ignored when global_fetch_cache has already installed
defaults; return or propagate an initialization error from the failed
GLOBAL_FETCH_CACHE setup and make server startup fail before request handling,
preserving the configured max_entries and max_bytes values.

In `@crates/rari/src/server/routing/app.rs`:
- Around line 81-104: Align the cache-key inputs with the render inputs in
handle_app_route and the related paths around extract_search_params: either
retain any query parameter that can affect rendering in the filtered cache map,
or remove it from the search_params passed to rendering. Update all applicable
cache-key and render flows, including the referenced sections, and add an
integration test proving requests with different values of a filtered parameter
cannot reuse the same cached content.

2089-2140: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Add mixed-case tracking keys to the tests.

is_cache_noise_query_param lowercases keys before matching, but the tests use only lowercase names. Add mixed-case cases such as UTM_SOURCE and FbClId to protect the case-insensitive behavior.
