SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve?

This Skill provides reusable JWT authentication utilities for FastAPI and Python projects, reducing boilerplate for token generation, verification, and user extraction.

Core Features & Use Cases

  • Generate and verify JWT tokens with standard claims (sub, exp, roles) for FastAPI apps.
  • Extract authenticated user details via dependencies; support role-based access checks.
  • Integrate with existing frontend authentication flows and backend security practices.

Quick Start

Install or import the jwt-auth components into your FastAPI project. Create a token with create_access_token(data={"sub": "[email protected]", "roles": ["admin"]}). Protect endpoints with a dependency that retrieves the current user from the token. For example, define a dependency using get_current_user and apply it to your routes to enforce authentication and RBAC.

FAQPage Schema
How do I add JWT authentication to a FastAPI backend?

You add JWT authentication to a FastAPI backend by importing utilities to generate HS256-signed access tokens and applying dependencies to routes for user extraction and request validation.

What is the best way to implement role-based access control in FastAPI?

Implement role-based access control (RBAC) in FastAPI by embedding roles within standard JWT claims and applying access check dependencies to endpoints. This enforces authorization based on the extracted user details.

Can I use this to integrate Python JWT verification with an existing frontend authentication flow?

Yes, this provides a straightforward integration path with existing frontend authentication flows. The backend verifies issued access tokens, extracts authenticated user details, and validates requests via dependencies.

Does this handle JWT expiration and standard claims like sub and exp?

Yes, this handles proper exp expiration management and supports standard JWT claims including sub for subjects and roles. It issues access tokens containing these fields for secure FastAPI authentication.

How do I protect FastAPI endpoints and extract the current user from a token?

Protect FastAPI endpoints by defining a dependency using get_current_user and applying it to your routes. This dependency retrieves and extracts the authenticated user details from the verified JWT.
