Questions tagged [opa]

Opa is an open source programming language for both backend and frontend web development. Opa therefore provides a unified syntax and semantics for writing all aspects of a web application: client-side, server-side and database queries. But it’s not only about expressiveness: Opa also features a unique type system that provides strong static typing from the client UI to the MongoDB queries.
