Nedo.AspNet.Authentication.Abstractions

Zero-dependency contracts for the Nedo.AspNet.Authentication modular auth platform. Reference this from your own libraries when you want to depend on the auth contracts (IAuthContext, IAuthEventSink, AuthMode, AuthEvent, AuthEventTypes) without pulling in ASP.NET Core itself.

Install

dotnet add package Nedo.AspNet.Authentication.Abstractions

What's in here

Type Purpose
IAuthContext DI-injectable identity surface — UserId, Email, IsAuthenticated, ExpiresAt, etc. Replaces direct HttpContext.User access.
AuthMode Anonymous / Optional / Required — drives the middleware policy decision.
IAuthEventSink Audit-log + side-channel hook (login.success, password.reset_requested, magic_link.requested, passkey.registered, …). Default impl is a no-op; host implements to ship events to Serilog / SIEM / OpenTelemetry / email delivery.
AuthEvent + AuthEventTypes Event envelope + the well-known type constants.
NoopAuthEventSink Default registration.

The full sink event-type list is in docs/local/internals.md on the repo.

Why a separate package

Domain libraries that want to assert "the caller must be authenticated and own this resource" can depend on IAuthContext from this package without taking on the full HTTP-stack dependency. Tests can mock IAuthContext without spinning up a WebApplicationFactory.

Package Role
Nedo.AspNet.Authentication Provides AuthContext + middleware that populate the IAuthContext from JWT bearer claims.
Nedo.AspNet.Authentication.Local Username/password / magic-link / refresh-token sign-in that emits sink events.
