@types/cache-manager

This is actually just a redirect package that points you to use cache-manager's built-in types, which is the right approach. When you install @types/cache-manager, you'll see it's essentially a stub that tells TypeScript to use the types from the main cache-manager package. This means zero maintenance burden and guaranteed type accuracy.

In practice, you don't really interact with this package directly - you just import from 'cache-manager' and TypeScript handles everything. The types themselves (from cache-manager) are well-structured with clear interfaces for Cache, Store, and Config objects. Type inference works smoothly when setting and getting cached values, and the async/await patterns are properly typed.

One minor gotcha: if you're migrating from older versions where types were separate, you might need to clean up duplicate type declarations. The error messages when types mismatch are standard TypeScript fare - clear enough if you understand the cache-manager API, but won't hold your hand through learning it.

This is a stub package that redirects to the native TypeScript definitions provided by cache-manager itself. In practice, you don't actually use this package anymore - cache-manager v5+ bundles its own types. The stub exists purely for backward compatibility and to prevent breaking existing projects that have @types/cache-manager in their dependencies.

The actual developer experience depends entirely on cache-manager's own type definitions. When they're present and correct, everything works seamlessly and you get good autocomplete for methods like set(), get(), wrap(), and store configuration. However, the redirect approach can cause confusion during setup - newcomers often install both packages unnecessarily, and dependency conflicts can arise if versions are mismatched.

The main pain point is documentation clarity. There's no clear explanation in npm or typical install flows that this is just a pointer package. You might spend time troubleshooting type issues thinking @types/cache-manager is the source, when actually you need to check cache-manager's bundled definitions.

This package is essentially a redirect stub since cache-manager v5+ includes its own TypeScript definitions. When you install it, you'll immediately see it points you to use the types from cache-manager directly. The transition is straightforward - you simply remove @types/cache-manager from your dependencies and the types continue working perfectly.

In practice, the actual cache-manager types are well-structured with clear interfaces for Cache, CacheStore, and configuration options. Type inference works reliably when setting and getting cached values, and the generic types allow proper typing of your cached data. Error messages are helpful when you misuse the API, like forgetting to await async operations or passing incorrect store configurations.

The main gotcha is understanding the version compatibility - cache-manager v4 and earlier need the separate @types package, while v5+ has built-in types. The migration path between these versions can be confusing initially, but once you understand the versioning, it's smooth sailing. Day-to-day usage with proper types makes caching operations predictable and reduces runtime errors significantly.
