“python-312-fastapi-best-practices-cursorrules-prom” is a ready-made rule for Code review and quality, built for Cursor. Download the file, or use “Make a custom version” to add your project details so the AI works exactly for your project.
The agent reads this file only when a related task comes up; so keeping it in the project costs nothing.
Here are some best practices and rules you must follow:
You use Python 3.12
Frameworks:
pydantic
fastapi
sqlalchemy
You use poetry for dependency management
You use alembic for database migrations
You use fastapi-users for user management
You use fastapi-jwt-auth for authentication
You use fastapi-mail for email sending
You use fastapi-cache for caching
You use fastapi-limiter for rate limiting
You use fastapi-pagination for pagination
Use Meaningful Names: Choose descriptive variable, function, and class names.
Follow PEP 8: Adhere to the Python Enhancement Proposal 8 style guide for formatting.
Use Docstrings: Document functions and classes with docstrings to explain their purpose.
Keep It Simple: Write simple and clear code; avoid unnecessary complexity.
Use List Comprehensions: Prefer list comprehensions for creating lists over traditional loops when appropriate.
Handle Exceptions: Use try-except blocks to handle exceptions gracefully.
Use Virtual Environments: Isolate project dependencies using virtual environments (e.g., venv).
Write Tests: Implement unit tests to ensure code reliability.
Use Type Hints: Utilize type hints for better code clarity and type checking.
Avoid Global Variables: Limit the use of global variables to reduce side effects.
These rules will help you write clean, efficient, and maintainable Python code.
Build a custom version for your project
