Speed up your application by storing frequently accessed data in a pluggable cache store — Memory, Redis, Kysely, and MongoDB adapters included.

Manage files with a unified API across local filesystem, in-memory, and cloud providers like AWS S3.

Publish and subscribe to events across distributed server instances or entirely in-memory for local testing.

Prevent cascading failures with an automatic circuit-breaker primitive that stops calls to a consistently failing service.

Guarantee mutual exclusion across multiple processes with a distributed lock, eliminating race conditions on shared resources.

Limit concurrent access to a resource or code section across processes with a configurable distributed semaphore.

Coordinate readers and writers efficiently — allow concurrent reads while ensuring exclusive, safe writes across processes.

Add custom serialization and deserialization logic that integrates transparently with every other component in the library.

Effortlessly work with Arrays, Iterables, and AsyncIterables using a rich, composable, and lazy collection API.

Intercept and compose any sync or async function with a priority-based middleware pipeline. Built-in retry, fallback, and timeout middlewares for handling transient failures.

Propagate request-scoped data — user info, trace IDs, tenant context — across async boundaries. Integrates transparently with all components and adapters.
