axum-impl-auth-jwt

What problem does it solve?

It eliminates insecure or incorrect JWT authentication patterns in Axum services by ensuring stateless bearer-token verification is implemented correctly and consistently.

Core Features & Use Cases

• Type-enforced route protection: Implements Claims as a FromRequestParts extractor so any handler that takes claims: Claims is automatically protected.
• Correct JWT validation behavior: Requires an exp claim and uses Validation::default() so expired or missing-exp tokens are rejected reliably.
• Safe error handling: Centralizes failures in an AuthError enum that implements IntoResponse, preventing raw jsonwebtoken error leakage to clients.
• Version-aware Axum guidance: Handles the Axum 0.7 vs 0.8 differences (notably #[async_trait] usage and typed-header imports).

Quick Start

Ask the AI to implement Axum JWT authentication for your login route and protect a /protected handler using Claims so that Axum 0.8 compiles and returns clean 401/400 responses for invalid tokens.
