 ## Preface
 
-Lots of rules engines use custom predicates, or predicates available from other libraries. [json-rules-engine](https://github.com/CacheControl/json-rules-engine) uses custom [Operators](https://github.com/CacheControl/json-rules-engine/blob/master/src/engine-default-operators.js) and [json-rules-engine-simplified](https://github.com/RxNT/json-rules-engine-simplified) uses the [predicate](https://github.com/landau/predicate) library. One thing that seems to have gotten missed is that **a json schema _IS_ a predicate** - a subject will either validate against a JSON schema, or it won't. Therefore, the only thing you need to write rules is a schema validator, no other dependencies needed. The other benefit of this is that if you need to use a new operator, your dependency on this library doesn't change. You either get that logic for free when the JSON Schema specification updates, or you add that operator to your [validator[](#validator), but to to this rules engine itself.

 This library doesn't do a whole lot - it just has an opinionated syntax to make rules human readable - which is why it's less than 2kb minzipped. You just need to bring your own validator (may we suggest [Ajv](https://github.com/ajv-validator/ajv)?) and write your rules.
