Peer dependency: @run-iq/core >= 0.1.0

Usage

import { PPEEngine } from '@run-iq/core';
import { JsonLogicEvaluator } from '@run-iq/dsl-jsonlogic';

const engine = new PPEEngine({

  },
  // ...
};

API

JsonLogicEvaluator

Implements DSLEvaluator from @run-iq/core.

| Property | Value | |---|---| | dsl | "jsonlogic" | | version | "1.0.0" |

evaluate(expression, context) — evaluates a JSONLogic expression against a data context and returns a boolean.

Timeout and sandboxing are handled by the core engine's PluginSandbox — this evaluator stays pure.

Requirements

• Node.js >= 20
• @run-iq/core >= 0.1.0
