# @standardserver/shared
`@standardserver/shared` contains internal types and utilities shared across the `@standardserver` ecosystem β small helpers for arrays, objects, JSON, iterators, promises, queues, IDs, URIs, and more.
It has no runtime dependencies and works in any JavaScript environment. The package exists so the other `@standardserver` packages can share these building blocks without duplication; its API follows their needs and is not designed for direct use in applications.
Standard Server ships as a small ecosystem of packages:
