FastAPI Templates

Create production-ready FastAPI projects with async patterns, dependency injection, and…

Production-ready FastAPI project scaffolding with a clean layered structure, async-everywhere patterns, dependency injection and consistent error handling. Instead of starting from a blank main.py, you get a proven api/core/models/schemas/services/repositories layout with working code for every layer.

The skill scaffolds a FastAPI backend where every layer has one job and every layer is testable alone. The build order it follows:

  1. Lays down the layered structure: api routes, core (config, security, database), models, Pydantic schemas, services, repositories. Business logic in route handlers is treated as a defect, not a shortcut.
  2. Wires the application lifecycle: a lifespan context manager connects the database pool at startup and disconnects at shutdown, and a get_db dependency yields an AsyncSession that commits on success and rolls back on exception, per request.
  3. Implements a generic repository (get, get_multi, create, update, delete) that only does data access, then a service layer on top that owns business rules: email uniqueness checks, password hashing, authorization decisions.
  4. Keeps a strict schema boundary: separate UserCreate, UserUpdate and UserResponse Pydantic models, so ORM entities never leak hashed passwords into responses and the API contract can change without touching domain models.
  5. Routes stay thin HTTP adapters: services raise ValueError, endpoints catch it and translate to HTTPException with the right status code. Auth is a chained dependency (oauth2 scheme inside get_current_user inside the route) that FastAPI resolves automatically.
  6. Tests every layer through dependency overrides: app.dependency_overrides swaps get_db for an in-memory SQLite session, so async integration tests with httpx hit the full stack without a real database.

Who it's for

This wasn't forged for everyone.

  • Not for you if you'd rather rent a tool than own one.
  • Not for you if you want someone else to run your stack.
  • Not for you if you're happy guessing.
Still here? Good.

Python backend developers spinning up new FastAPI services or microservices who want a clean, async, testable foundation from day one.

Questions · still in the air

Catch what's on your mind.

the air is clear. nothing between you and the forge.
catch a spark: the forge will answer

  1. Does this lock me into a specific database or ORM?

    No, the layered route-service-repository structure is storage-agnostic, so you slot in SQLAlchemy, an async driver or whatever you prefer. The scaffolding shapes the boundaries, not the database choice.

  2. Isn't a template just someone's opinions I'll end up fighting?

    The structure is conventional and the layers are swappable, so it removes the blank-file decisions rather than dictating your domain. Where your service needs to deviate, the boundaries are clean enough to do it.

  3. Does it include auth, deployment and my business logic?

    No, it is the async, layered foundation with dependency injection and error handling, not your features. Authentication, domain logic and deployment are yours to add on top.

  4. How is it delivered?

    By email right after purchase: ready to run, downloaded instantly, no setup wait.

  5. One-time or subscription?

    A one-time purchase; no subscription or hidden fees. VAT (20%) is included.

  6. Can I get a refund?
