Aqueduct
Dart HTTP server framework for building REST APIs
... a statically-typed ORM, OAuth 2.0 provider, automated testing libraries, and OpenAPI 3.0 integration. Aqueduct's memory-isolated threads leverage every CPU without writing any code. No race conditions or complicated synchronization logic to worry about. A familiar, higher-order functional syntax makes application flow easy to construct and read. Powerful, statically typed queries enable code-completion and refactoring tools while minimizing error.
