Json Rules Engine Simplified

A simple rules engine expressed in JSON


The json-rules-engine-simplified is a simplified rules engine expressed in JSON. It aims to be an alternative to json-rules-engine for react-jsonschema-form-conditionals, offering a similar interface and configuration but with a simplified predicate language akin to SQL.


  • Optional schema and rules validation
  • Basic boolean operations (and, or, and not) allowing for arbitrary complexity
  • Rules expressed in simple, easy-to-read JSON
  • Declarative conditional logic with predicates
  • Support for relevant conditional logic and nested structures with selectn
  • Secure - avoids the use of eval()


To install json-rules-engine-simplified, run the following command:

npm install json-rules-engine-simplified


The json-rules-engine-simplified offers a simplified approach to creating and implementing rules in JSON format. With features like optional validation, basic boolean operations, and support for nested structures, it aims to provide a secure and efficient solution for implementing conditional logic in applications.
