FastAPI Project Templates

Starting-point FastAPI project structures with async patterns, dependency injection, middleware, and best practices for building high-performance APIs.

Use this skill when

• Starting new FastAPI projects from scratch
• Implementing async REST APIs with Python
• Building high-performance web services and microservices
• Creating async applications with PostgreSQL, MongoDB
• Setting up API projects with proper structure and testing

Do not use this skill when

• The task is unrelated to fastapi project templates
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Example

Create a PostgreSQL-backed user API using the playbook. First define request/output/internal schemas and object authorization, then test registration, inactive-token rejection and forbidden cross-user reads. Report missing project files before claiming a runnable service.

Resources

• resources/implementation-playbook.md for detailed patterns and examples.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
