R-Think
Getting Started

Get Started with R-Think

This guide walks you through installing R-Think, creating a project, and executing your first structured reasoning flow.

Prerequisites

  • Node.js 18.0 or higher
  • npm 9.0 or higher
  • TypeScript 5.0 or higher (recommended)

Installation

Install R-Think using npm. The runtime package includes the core engine, protocol definitions, and validation rules.

Terminal bash
npm install @r-think/core

Version Note

R-Think follows semantic versioning. Check the Download page for the latest stable version.

Create Project

Create a new project directory and initialize your reasoning flow.

Terminal bash
mkdir my-rthink-project
cd my-rthink-project
npm init -y

Hello World

Create your first reasoning flow. This example demonstrates a simple sequential protocol with validation rules.

hello-world.ts typescript
import { Runtime, Protocol, Rule } from '@r-think/core';

const runtime = Runtime.create({
  id: 'hello-world',
  protocol: Protocol.sequential,
  rules: [
    Rule.required('message'),
    Rule.type('message', 'string')
  ]
});

const result = await runtime.execute({
  message: 'Hello, R-Think'
});

console.log(result.output);   // { message: 'Hello, R-Think' }
console.log(result.trace);     // Full reasoning trace
console.log(result.validated); // true

Validation

Rules validate inputs, outputs, and state transitions. Invalid data is rejected before reasoning proceeds.

validation.ts typescript
const runtime = Runtime.create({
  id: 'validated-flow',
  protocol: Protocol.sequential,
  rules: [
    Rule.required('input'),
    Rule.bounded('score', 0, 100),
    Rule.matches('email', /^[^\s@]+@[^\s@]+\.[^\s@]+$/),
    Rule.enum('status', ['pending', 'approved', 'rejected'])
  ]
});

// Invalid: score out of bounds
try {
  await runtime.execute({ score: 150 });
} catch (error) {
  console.log(error.message); // Rule violated: score must be between 0 and 100
}

Tip

Define rules close to the protocol definition. This makes validation requirements explicit and maintainable.
