Configurable Backend Engine

A powerful Low/No Code Tool to build Backend Rest APIs by using visual building blocks. Create complex API endpoints through an intuitive drag-and-drop interface without writing extensive code.

🚀 Features

  • Visual API Builder: Design APIs using drag-and-drop blocks
  • No Code Required: Build complex logic without programming knowledge
  • Extensible Architecture: Add custom blocks for specialized functionality
  • Real-time Execution: See your API changes instantly
  • Type Safety: Built with TypeScript for reliability
  • Database Integration: Seamless ORM integration with Drizzle
  • Transaction Support: Atomic operations for data consistency

🏗️ Architecture

The Configurable Backend Engine consists of several key components:

Core Components

  • Block Engine: Executes the visual workflow defined by blocks
  • Admin API: RESTful API for managing routes, blocks, and edges
  • UI Editor: Web-based visual editor for designing APIs
  • Database Layer: PostgreSQL with Drizzle ORM for data persistence

Block System

Blocks are the fundamental building units that define API behavior:

  • Entrypoint Block: Entry point for all API requests
  • Processing Blocks: Transform, validate, and manipulate data
  • Control Flow Blocks: Conditional logic and loops
  • HTTP Blocks: Handle request/response operations
  • Response Block: Final output generation

🎯 Use Cases

  • Rapid Prototyping: Quickly build and test API endpoints
  • Business Logic Automation: Implement complex workflows visually
  • Data Processing Pipelines: Create ETL processes without code
  • API Orchestration: Combine multiple services and data sources
  • Webhook Processing: Handle and transform webhook payloads

🛠️ Quick Start

  1. Install Dependencies 

    npm install

  2. Start Development Server 

    npm run dev

  3. Open Editor Navigate to http://localhost:3000 to start building your APIs

  4. Create Your First Route

  5. Use the visual editor to drag and drop blocks
  6. Connect blocks to define your API logic
  7. Test your endpoint instantly
