Learning Path for FastAPI​

Week 1: Foundations​

Days 1-2: Environment setup

  • Install FastAPI and required tools
  • Set up your development environment
  • Run the official "Hello World"

Days 3-5: Core concepts

  • Work through official tutorials
  • Understand the fundamental mental models
  • Build something small but complete

Week 2-1: Building​

  • Build a real project you care about
  • Learn common patterns and best practices
  • Start reading other people's code

Week 2-2: Production Ready​

  • Understand testing patterns
  • Learn debugging strategies
  • Explore advanced features

Common Challenges When Learning FastAPI​

  • Async programming: Understand when to use async vs sync functions
  • Dependency injection: Learn the Depends() system for clean code
  • Pydantic models: Master Pydantic for validation and serialization

Prerequisites​

Before learning FastAPI, you should be comfortable with:

  • Python
  • Type hints
  • HTTP concepts

How Ramp Accelerates FastAPI Onboarding​

Ramp helps developers onboard to FastAPI codebases faster:

# Point Ramp at a FastAPI project
ramp init

# Ask questions about FastAPI patterns
ramp voice
> "How is FastAPI used in this codebase?"
> "What's the pattern for X in this project?"
> "Explain how this FastAPI code works"
