RuleScribe is a lightweight and powerful rule engine for JavaScript and TypeScript applications. It allows you to define and execute business rules in a declarative manner, enabling agile decision-making and automation of complex logic.

You can install RuleScribe via npm:

npm install rulescribe

To define a simple rule using RuleScribe, follow these steps:

1. Import the required modules:

   import { Engine, Lexer, EngineScope } from "rulescribe";

2. Define the structure of the entity for which you're defining rules. For example, let's define a Patient type:

   type Patient = {
       name: string;
       lastVisit: number;
   }

3. Define a method to perform an action based on the rule. For example, let's define a method to send a checkup reminder SMS to a patient:

   const sendCheckupReminderSMS = (patient: Patient) => {
       // Your business logic to send SMS goes here.
   }

4. Write the rule:

   const rule = `
   Rule "My First Rule"
   When patient.lastVisit > 90
   Then
       sendCheckupReminderSMS(patient)
   End
   `

5. Set up the RuleScribe engine and execute the rule:

   const scope = new EngineScope();
   scope.builtinFunction.set("sendCheckupReminderSMS", {
       func:  sendCheckupReminderSMS
   });
   
   const lexer = new Lexer(rule, scope);
   const engine = new Engine(lexer);
   
   // Define the patient
   scope.define('patient', { name: "John Doe", lastVisit: 100 });
   
   // Parse and execute the rule
   await engine.parse(scope);
   await engine.fire(scope);

This code will execute the rule "My First Rule" and send a checkup reminder SMS to the patient if their last visit was more than 90 days ago.
