Introduction

Krestianstvo SDK 4 is the Open Source implementation of the Croquet application architecture in Functional Reactive Paradigm.

Krestianstvo SDK 4 is mainly developed using Solid JS with the prototype in S.JS. Other implementations are also underway for Rust, Swift and Squeak Smalltalk programming languages.

The applications built with Krestianstvo SDK 4 are using just Signals, Effects and reactive computations to get the original scene of Croquet’s Objects with Message passing but implemented in Functional Reactive Paradigm (FRP).

Virtual Time and Reflector are based on Virtual World Framework’s implementation, modified to suit FRP. Support for running applications built with SDK in peer-to-peer Web, mesh and decentralised networks even without Reflector server is underway, by using Krestianstvo Luminary.

Krestianstvo SDK 4 - is minimal and distributed as a standalone ESM JavaScript module to be bundled within any Solid JS or Astro web applications.

Getting all the benefits from Functional Reactive Paradigm (FRP), Krestianstvo SDK 4 become just an ideal framework for developing and deploying multi-user, collaborative serverless apps with ease. It is brining closer to the realisation the ideas about an End-User Mobile Web XR Virtual Learning Environment founded in the previous versions of Krestianstvo SDK.
