FastAPI + React Prompt Architecture

Generate prompts that produce type-safe FastAPI endpoints with Pydantic validation and auto-generated React API clients.

Model-agnostic prompts

Stack-aware constraints

Production-ready output

❌ The Problem

AI models produce FastAPI code with synchronous blocking calls, missing Pydantic validation, and no OpenAPI schema.

✅ The Solution

Prompt Architect generates async-first FastAPI prompts with Pydantic v2 models, proper dependency injection, and OpenAPI documentation.

How It Works

Three steps to production-quality Python code

🐍

STEP 1

Define API Schema

Specify your Pydantic models, database tables, and authentication flow.

⚡

STEP 2

Generate Full-Stack Prompts

Get FastAPI endpoint prompts with matching React hooks via auto-generated OpenAPI client.

🚀

STEP 3

Deploy Async APIs

Generate production-ready async endpoints with proper error handling and background tasks.

Frequently Asked Questions

Does it support Pydantic v2?

Yes — model_validator, field_validator, ConfigDict, and proper JSON Schema generation.

Can it generate async SQLAlchemy?

Prompts include async session management, proper async/await patterns, and connection pooling.

Can it help generate type-safe API clients?

Yes — prompts include OpenAPI schema constraints that pair with openapi-typescript for React type-safe clients.

Technical Deep Dive

How do I set up the initial project architecture with these technologies?

Use AI Prompt Architect to generate a scaffold prompt that includes directory structure, configuration files, environment setup, and dependency installation commands tailored to your exact stack combination. The prompt enforces best-practice file organisation from the start.
