What is RANA?

RANA (React Agent Next Architecture) is a professional framework for building production-ready AI agents with React and Next.js. It provides a complete architecture for developing, deploying, and scaling intelligent applications.

Why RANA?

Building AI agents from scratch is challenging. You need to handle:

  • LLM integration and API management
  • Streaming responses and real-time updates
  • State management and conversation history
  • Error handling and retry logic
  • Security, rate limiting, and cost optimization
  • Authentication and authorization
  • Database integration and caching
  • Production deployment and monitoring

RANA solves all of these problems with a cohesive, type-safe framework that follows industry best practices.

Core Principles

1. Type Safety First

RANA is built with TypeScript from the ground up. Every API, hook, and component is fully typed with comprehensive inference. You get autocomplete and compile-time error checking throughout your entire application.

import { useAgent } from '@rana/react';

// Full type inference
const { send, messages, isLoading } = useAgent({
  model: 'gpt-4',
  systemPrompt: 'You are a helpful assistant',
});

// TypeScript knows the exact shape of messages
messages.map(msg => msg.content); // ✅ Type-safe

2. Production Ready

RANA isn't a toy framework—it's designed for real-world applications. It includes:

  • Built-in security framework with input validation
  • Rate limiting and cost controls
  • Database integration with Supabase
  • Authentication and session management
  • Monitoring and observability
  • SEO optimization for AI-powered content

3. Developer Experience

RANA prioritizes developer productivity with:

  • Simple, intuitive APIs
  • Comprehensive documentation and training
  • CLI tools for scaffolding and management
  • Hot module replacement and fast refresh
  • Detailed error messages

4. Performance Optimized

Every part of RANA is optimized for performance:

  • Streaming responses for instant feedback
  • Intelligent caching to reduce API calls
  • Prompt optimization and compression
  • Lazy loading and code splitting
  • Edge runtime support

Framework Architecture

RANA consists of three main packages:

@rana/core

The core LLM client library. Handles API communication, streaming, error handling, and retry logic. Works with any JavaScript environment.

@rana/react

React hooks and components for building AI interfaces. ProvidesuseAgent, useChat, and other hooks for managing agent state.

@rana/cli

Command-line tools for project initialization, validation, and deployment. Includes generators for common patterns and best practices.

Who Should Use RANA?

RANA is perfect for:

  • Startups building AI-powered products who need to move fast without sacrificing quality
  • Agencies delivering AI projects for clients with tight deadlines
  • Enterprise teams requiring a secure, scalable architecture for internal tools
  • Indie developers wanting to ship production-ready AI apps without reinventing the wheel
