60 Prompts for Building FastAPI Web Apps

A complete reference of example prompts to build FastAPI web applications — from project scaffold to production deploy, integrations, and real-world apps.

---

Getting Started & Project Setup

1. "Build a FastAPI web app with a clean project structure — app/main.py, routers/, models/, schemas/, and database.py."
2. "Create a FastAPI project scaffold with requirements.txt, .env config, and a README with run instructions."
3. "Set up a FastAPI app with CORS enabled for a React frontend running on a different port."
4. "Add environment-based configuration to a FastAPI app — dev, staging, and prod settings via pydantic-settings."

Database & Models

5. "Build a FastAPI app with SQLAlchemy models and a PostgreSQL database, including a migration setup."
6. "Create a FastAPI CRUD API for a 'products' table — GET, POST, PUT, DELETE endpoints with proper Pydantic schemas."
7. "Add async SQLAlchemy support to a FastAPI app using asyncpg for PostgreSQL."
8. "Set up SQLite for local development and PostgreSQL for production in the same FastAPI app."

Authentication & Security

9. "Add JWT authentication to a FastAPI app — login endpoint, token refresh, and protected routes."
10. "Implement OAuth2 password flow with hashed passwords (bcrypt) for user signup and login in FastAPI."
11. "Add role-based access control (admin/user) to FastAPI routes with dependency injection."
12. "Secure a FastAPI API with API-key authentication for third-party clients."

Validation & Schemas

13. "Build Pydantic schemas with validation for a user registration form — email format, password strength, and field constraints."
14. "Add request/response models with nested serialization for a blog app — posts with author and comments."
15. "Create a FastAPI endpoint that accepts file uploads with size and type validation."

Advanced Features

16. "Add pagination, sorting, and filtering to a FastAPI list endpoint for a large dataset."
17. "Build a background task system in FastAPI — run a job in the background and poll its status."
18. "Add WebSocket support to a FastAPI app for real-time chat or live notifications."
19. "Implement rate limiting on a FastAPI API to prevent abuse."
20. "Add full-text search to a FastAPI app using PostgreSQL's built-in search features."

Testing & Quality

21. "Write unit tests for FastAPI endpoints using pytest and TestClient."
22. "Set up automated tests with a test database fixture that runs against a clean schema."
23. "Add request logging and structured error handling to a FastAPI app."

Docs & Production

24. "Customize FastAPI's auto-generated Swagger docs — add descriptions, tags, and examples to all endpoints."
25. "Containerize a FastAPI app with Docker and docker-compose, including the database service."
26. "Deploy a FastAPI app with Gunicorn + Uvicorn workers behind an Nginx reverse proxy."
27. "Add health-check and readiness endpoints to a FastAPI app for Kubernetes or Docker health probes."
28. "Set up automatic OpenAPI schema generation and versioned API routes (/v1, /v2)."

Real-World Examples (Batch 1)

29. "Build a complete FastAPI todo app with a frontend — CRUD endpoints, SQLite, and a simple HTML/JS interface."
30. "Create a FastAPI REST API for a small e-commerce store — products, orders, cart, and checkout endpoints."

---

Integrations & Third-Party Services

31. "Build a FastAPI app that sends emails via SMTP — a contact form endpoint that renders an HTML template."
32. "Create a FastAPI endpoint that uploads files to S3 (or a cloud bucket) and returns the public URL."
33. "Add Stripe payment integration to a FastAPI app — create a checkout session and handle the webhook."
34. "Build a FastAPI app that calls an external REST API (e.g. weather or news) and caches responses in Redis."
35. "Add Google OAuth login to a FastAPI app with social auth and session persistence."

Async & Performance

36. "Rewrite a slow synchronous FastAPI endpoint as async with httpx to make concurrent external calls."
37. "Add Redis caching to a FastAPI app for expensive database queries with a TTL-based cache layer."
38. "Build a FastAPI app that streams large files or data in chunks with StreamingResponse."
39. "Add database connection pooling to a FastAPI app and explain how to tune pool size."
40. "Implement a job queue in FastAPI using Celery or RQ — enqueue a task, track its status, and fetch results."

Data Processing & AI

41. "Build a FastAPI app that accepts a CSV upload, processes it with pandas, and returns summary statistics as JSON."
42. "Create a FastAPI endpoint that runs a machine-learning model (pickle/onnx) and returns predictions."
43. "Add a text-summarization or sentiment-analysis endpoint to a FastAPI app using a Hugging Face model."
44. "Build a FastAPI app that generates embeddings and stores them in a vector database (pgvector) for similarity search."
45. "Create a FastAPI image-upload endpoint that resizes/compresses images with Pillow and stores them."

Templating & Frontend

46. "Build a FastAPI app with Jinja2 templates — a server-rendered multi-page site with a base layout."
47. "Add static files (CSS/JS/images) to a FastAPI app and wire them into Jinja templates."
48. "Create a FastAPI app that serves a single-page React build from a dist/ folder."

Error Handling & Middleware

49. "Add custom exception handlers to a FastAPI app — return structured JSON errors with proper HTTP codes."
50. "Build a FastAPI middleware that logs every request with method, path, status, and duration."
51. "Add request timing and a simple metrics endpoint (/metrics) exposing request counts and latencies."
52. "Implement a global exception handler that catches unhandled errors and returns a safe 500 response."
