CertLogic implementations

Several implementations of CertLogic and compatible implementations of JsonLogic exist - links to these are given below. Note that the compatibility of JsonLogic implementations does not necessarily include the custom operations, such as plusTime, and extractFromUVCI. These custom operations:

• Are defined in the CertLogic specification.
• Can be implemented by mimicking any of the existing implementations in
  • Java-/TypeScript,
  • Kotlin,
  • or Dart.
• Can be tested using the test suite, and by mimicking the various unit tests available, such as:
  • in Java-/TypeScript
  • in Kotlin
  • in Dart.

JavaScript (TypeScript)

certlogic-js: a TypeScript implementation, usable from JavaScript as well, and available as NPM package. It can be installed by running

$ npm certlogic-js

and adding the following import to TS/ES6+ source

import { evaluate } from "certlogic-js"

or the equivalent ES6- statement

const { evaluate } = require("certlogic-js")

JVM

• certlogic-kotlin: a greenfield Kotlin implementation, Releases are available on GitHub, and also as GitHub Package. Note that you have to modify your ~/.m2/settings.xml to be able to retrieve a GitHub Package: see this page.

• json-logic-java: Java implementation of JsonLogic which has been verified to comply with the CertLogic test suite. Releases are available on GitHub, and also on Maven Central.

Swift

json-logic-swift: a Swift implementation of JsonLogic, conforming to the CertLogic spec. Releases are available on GitHub.

Go

• json-logic-go: an implementation of JsonLogic in Go, contributed through the hard work of Ilie Circiumaru.

Dart

• certlogic-dart: a Dart implementation of CertLogic.
