This is an implementation of the data structures and algorithms described in the paper A Conflict-Free Replicated JSON Datatype (PDF) by Martin Kleppmann and Alastair R. Beresford.
The goal of this project is to provide a high-level API to the CRDT described in the paper that integrates well with other JSON libraries for Scala.
crjdt is currently available for Scala and Scala.js, version 2.11 and 2.12.
To get started with sbt, add the following to your build.sbt file:
libraryDependencies ++= Seq(
"eu.timepit" %% "crjdt-core" % "0.0.6",
"eu.timepit" %% "crjdt-circe" % "0.0.6" // optional
)Instructions for Maven and other build tools are available on the Scaladex page.
crjdt is currently maintained by Frank S. Thomas.
The crjdt project supports the Typelevel code of conduct and wants all of its channels (Gitter, GitHub, etc.) to be welcoming environments for everyone.
Currently crjdt is the only public implementation of the JSON CRDT. We will list other implementations here as soon as they become available.
If you know an implementation that is not listed here, please submit a PR!
