📝 WalkthroughWalkthroughThe middleware cache now supports global and annotated read caching, miss deduplication, named stores, namespaces, mutation invalidation, model and generation strategies, detached operations, telemetry, and expanded cache-store APIs. ChangesMiddleware cache
Estimated code review effort: 4 (Complex) | ~60 minutes Merge Risk: 🟡 Moderate · up to The change currently leaves some consumers unable to resolve the renamed package and can produce stale or incorrectly invalidated cache entries in specific key, tag, wildcard, and expiration scenarios. The PR is not merge-ready until these bounded integration and cache-correctness issues are fixed or explicitly accepted. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@packages/3-extensions/middleware-cache/package.json`:
- Around line 2-3: Update all public wrapper and integration manifests and
integration-test imports from `@internal/middleware-cache` to
`@prisma-next/middleware-cache`, matching the package name declared by the
middleware-cache package. Do not leave any consumer references to the old
package name.
In `@packages/3-extensions/middleware-cache/README.md`:
- Line 369: Update the “Reads of stale-on-arrival entries” guidance to remove
the undefined “storage-hash discrimination” reference and describe an actionable
mitigation using the documented cache-key mechanisms and a sensible TTL, without
introducing undocumented settings or APIs.
- Around line 23-27: Update the Dependencies section in the middleware-cache
README to list both direct production dependencies declared by the package
manifest: `@prisma-next/framework-components` and `@prisma-next/utils`. Keep the
descriptions accurate and remove the claim that framework-components is the only
production dependency.
- Line 116: Update the cache annotation documentation to distinguish
compile-time and runtime enforcement: explain that an `as any` cast only
bypasses TypeScript checking, while the write MetaBuilder and SQL mutation
builder still invoke `assertAnnotationsApplicable(..., 'write', ...)` and reject
the read-only cache annotation.
In `@packages/3-extensions/middleware-cache/src/cache-middleware.ts`:
- Around line 1101-1139: Update invalidateForAction so keys and tags are
processed independently rather than through a mutually exclusive else-if chain:
retain explicit-key deletion and index removal, then also call h.store.delByTag
for supplied tags, while preserving model/entity invalidation only when neither
selector is provided. Keep the UncacheAction contract consistent with keys and
tags being combinable.
- Around line 647-657: Update matchesNamespacePattern’s glob-escaping branch to
include ? in the escaped character class, while preserving wildcard * conversion
and the existing regex-pattern branch.
In `@packages/3-extensions/middleware-cache/src/cache-store.ts`:
- Around line 193-201: Update the expiry branch in get() to call
deleteCacheKey(key) instead of deleting directly from the map, ensuring tagIndex
references are removed before an expired key is replaced; add a regression test
covering expiration, replacement with different tags, and invalidation by the
old tag.
In `@packages/3-extensions/middleware-cache/test/cache-middleware.test.ts`:
- Line 1449: Update the test titles at the cases around the broad invalidation
test and the generation invalidation test to use the current CacheStrategyMode
names: replace “model” with “broad” and “generation” with “versioned”, matching
each test’s configured mode value.

Update consumers to @prisma-next/middleware-cache.
The public wrapper and integration manifests still declare @internal/middleware-cache, and integration tests still import it. No workspace package declares the old name, so these consumers cannot resolve the renamed package.

Escape ? in the glob branch of matchesNamespacePattern.
The escape class [.+^${}()|[\]\\] omits ?. A configured pattern such as tenant? becomes the regular expression ^tenant?$, so ? acts as a quantifier and the pattern matches tenan as well as tenant. The wrong NamespaceConfig then applies to an execution, which can select the wrong store or the wrong TTL.
Add ? to the escaped character class.

tags is silently ignored when keys is also set on the same action.
invalidateForAction uses an else if chain, so an action such as { keys: ['user:1'], tags: ['users'] } deletes the explicit key and never calls delByTag. The tagged entries stay in the store, which produces stale reads. The UncacheAction documentation in packages/3-extensions/middleware-cache/src/uncache-annotation.ts lines 6-12 describes keys and tags as independent selectors, so callers can reasonably combine them.
Either process tags independently of keys, or document the precedence in UncacheAction.

Remove tag references when an entry expires through get().
The new tagIndex requires cleanup on every deletion path. At Line 150, get() calls map.delete(key) directly. If an expired key is stored again with different tags, delByTag() for an old tag can delete the replacement entry.
Call deleteCacheKey(key) in the expiry branch. Add a regression test for expire, replace with new tags, then invalidate the old tag.

Update two test titles to the current strategy mode names.
CacheStrategyMode is 'broad' | 'targeted' | 'versioned'. Line 1449 says cacheStrategy.mode = model while the configuration uses mode: 'broad'. Line 1640 says cacheStrategy.mode = generation while the configuration uses mode: 'versioned'. The titles reference mode names that the public type no longer contains.

1449, Update the test titles at the cases around the broad invalidation test and
the generation invalidation test to use the current CacheStrategyMode names:
replace “model” with “broad” and “generation” with “versioned”, matching each
test’s configured mode value.

Summary
This PR improves middleware-cache behavior by introducing clearer cache/uncache semantics and expanding strategy coverage so cache invalidation and reuse are more predictable in real query flows.
The goal is to reduce stale-cache risk while keeping the middleware API type-safe and easier to apply consistently.
