majiayu000 Server Development Skill
Instructions
Use this skill to scaffold and maintain backend services in the server/ directory. Follow the stack preferences and configuration details below.
Quick Start
- Initialize:
uv init. - Manager: Use
uvfor all dependency operations. - Framework: Setup
FastAPIwithPydantic. - Database: configure
SQLAlchemy(Async) +Alembic.
Core Stack Preferences
Project Management (uv)
Use uv for all Python project management (scaffolding, dependency management, virtual environments).
| Command | Description |
|---|---|
uv init |
Initialize a new project |
uv add <pkg> |
Add dependency |
uv add --dev <pkg> |
Add development dependency |
uv run <cmd> |
Run command in virtual environment |
uv venv |
Create virtual environment |
Project Location
The backend project should be initialized in the server/ directory.
Framework (FastAPI)
Use FastAPI for building APIs.
- Use
APIRouterfor modularizing routes. - Use
pydantic-settingsfor configuration management.
Database (SQLAlchemy + Alembic)
Use SQLAlchemy 2.0+ with AsyncIO support. Use Alembic for database migrations.
AI & LLM (LiteLLM + Docling)
- LiteLLM: For standardized access to various LLM providers.
- Docling: For parsing and processing documents.
