Specification & Engineering Guide

Comprehensive technical overview, schema formats, step-by-step instructions, and operational boundaries for JSON to TypeScript, SQL & PHP DTO Schema Converter.

System Overview & Architecture

Translating API responses into typed data contracts across the frontend and backend is a repetitive task. Paste any JSON payload and immediately generate TypeScript interfaces, SQL tables, and PHP DTO classes in seconds.

Key Capabilities

  • TypeScript Interfaces: Clean typed contracts for frontend and backend TypeScript applications.
  • PostgreSQL DDL: Production-grade tables with auto-incrementing bigserial IDs and timestamps.
  • PHP 8.2 Readonly DTOs: Strict typing with constructor property promotion.

Step-by-Step Workflow Guide

  1. Paste your JSON payload into the input editor.
  2. Select your target dialect (TypeScript, PostgreSQL DDL, or PHP 8.2 DTO).
  3. Copy the generated code into your codebase.

Pro Engineer Tips & Optimization

Use the PHP DTO mode to create strongly-typed request and response models in Laravel or Symfony applications.
