Scala lightweight, type-safe, asynchronous driver (not opinionated on effect systems) for Neo4j

  • Scala - the driver provides you with support for all standard Scala types without the need to convert Scala <-> Java types back and forth and you can easily add support for your own types.
  • Lightweight - the core module of the driver only depends the Neo4j Java driver, and the generic module only depends on Shapeless.
  • Type-safe - the driver leverages typeclasses to derive all needed conversions at the compile time.
  • Asynchronous - the driver sits on top of asynchronous Java driver.
  • Not opinionated on side-effect implementation - you can use it with any effect system of your preference (Future, typelevel, ZIO, Monix) by implementing a simple typeclass.


⚠️ The library is under heavy development. Production use is at your own risk and is not recommended. ⚠️
