JSONLogic Validator

Implement and validate JSONLogic rules—portable, JSON-serializable business logic that works across JavaScript, Python, PHP, Ruby, Go, Java, .Net, and C++.

Core Syntax

Every rule: { "operator": [arguments] }

{"==": [1, 1]}                              // comparison
{"var": "user.name"}                        // data access
{"and": [{">=": [{"var": "age"}, 18]}, {"var": "active"}]}  // compound
