This project is designed such that business rules can be shared between the front-end and back-end, serialized in JSON.

🚀 Get Started

# install illogical
npm install @briza/illogical

// Import the illogical engine
import Engine from '@briza/illogical'

// Create a new instance of the engine
const engine = new Engine()

// Data context
const ctx = {
  name: 'peter',
  age: 21,
  address: {
    city: 'Toronto',
    country: 'Canada',
  },
}

// Evaluate an expression in the given data context
engine.evaluate(['>', '$age', 20], ctx) // true

// Accessing a property
engine.evaluate(['==', '$address.city', 'Toronto'], ctx) // true

// Data Type Casting
engine.evaluate(['==', '$age.(String)', '21'], ctx) // true

// Evaluate a logical expression
engine.evaluate(['AND', ['>', '$age', 20], ['==', '$name', 'peter']]) // true
