Interactive playground

​

What you can do

• Decision tables - Create spreadsheet-style conditional logic
• Expression nodes - Transform data with the ZEN expression language
• Function nodes - Write custom JavaScript for complex logic
• Switch nodes - Route data through conditional branches
• Simulator - Test your rules with sample data and see step-by-step execution

​

Getting started

1. Open the playground - Visit editor.gorules.io
2. Build your graph - Drag nodes onto the canvas and connect them
3. Add logic - Double-click nodes to configure rules, expressions, or code
4. Test - Click Open Simulator, enter test data, and run your decision
5. Export - Download the JDM file to use with GoRules SDKs

​

Try these examples

​

Pricing calculator

1. Add a Decision Table node
2. Configure inputs: customer.tier, order.total
3. Configure output: discount
4. Add rules for different scenarios

​

Eligibility checker

1. Add an Expression node to calculate derived values (age from birthdate, etc.)
2. Add a Decision Table to check eligibility criteria
3. Add another Expression to format the response

​

Risk scoring

1. Add multiple Decision Table nodes for different risk categories
2. Add an Expression node to combine scores
3. Add a Switch node to route to different outcomes based on total score

Embedding the editor

npm install @gorules/jdm-editor

import { useState } from 'react';
import { DecisionGraph, JdmConfigProvider } from '@gorules/jdm-editor';
import '@gorules/jdm-editor/dist/style.css';

function RuleEditor() {
  const [graph, setGraph] = useState({ nodes: [], edges: [] });

  return (
    <JdmConfigProvider>
      <DecisionGraph value={graph} onChange={setGraph} />
    </JdmConfigProvider>
  );
}
