crjdt: a conflict-free replicated JSON datatype in Scala
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.
Getting Started
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" % "0.0.7",
"eu.timepit" %% "crjdt-circe" % "0.0.7" // optional
)
For Scala.js just replace %%
with %%%
above.
Instructions for Maven and other build tools are available on the Scaladex page.
Contributors and participation
The crjdt project supports the Typelevel code of conduct and wants all of its channels (Gitter, GitHub, etc.) to be welcoming environments for everyone.
Other implementations
Here are other implementations of the JSON CRDT described in the paper by Kleppmann and Beresford.
If you know an implementation that is not listed here, please submit a PR!
Development
- Format your code with Scalafmt.
- Run a specific test with e.g.
sbt "test:testOnly eu.timepit.crjdt.core.examples.Figure1"
or all tests withsbt test
. - Documentation for Vertical Move is in the file
