FAPI 2.0 is the security profile required by Open Banking, healthcare APIs, and government identity systems. Most teams think conformance takes months. Granit’s OpenIddict server, BFF, and resource server implement every requirement — one flag enables the full profile.
Auth0 costs $240/month past 7 500 users. Keycloak needs its own VM and JVM tuning. Granit.OpenIddict ships as NuGet packages and runs in the same process as your API — full OIDC compliance, zero external services.
Rate limiting and bulkhead isolation are often mentioned together but solve different problems. This deep-dive explains both patterns, shows where they fail without the other, and walks through Granit’s dual enforcement model — Redis-backed quotas for the time axis, concurrency limiters for the thread axis.
W3C Web Push lets the browser ring even when your tab is closed. With VAPID you do it without FCM, without APNs, and without a single US-hosted dependency. Here is the .NET 10 side, the React hook, and the 30 lines of service worker that ties them together.
Wire Keycloak JWT Bearer authentication into a Granit API in five minutes — claims transformation, role mapping, back-channel logout, and an Admin authorization policy, all from one DependsOn.
Scattering validation across controllers, services, and entities produces inconsistent errors and missed cases. Pin it to the API boundary with FluentValidation and endpoint filters — and let the platform do the rest.
A dropped connection, a mobile retry, a load-balancer timeout — any of these can duplicate a POST. Idempotency keys turn dangerous replays into harmless no-ops, and Granit ships the entire pattern as a single middleware.
.NET 10 makes SSE a first-class citizen with TypedResults.ServerSentEvents(). Build a complete real-time notification stream from HTTP primitives to React hooks — no WebSocket plumbing required.
Stop returning bare strings from your .NET APIs. RFC 7807 Problem Details is the standard for error responses — here is why it matters, what the spec actually says, and how Granit enforces it with zero boilerplate.
Swashbuckle is unmaintained and has no OpenAPI 3.1 support. .NET 10 ships a native document generator. Here is how to replace Swagger UI with Scalar — and what Granit’s ApiDocumentation module does for you automatically.
Returning EF Core entities directly from your endpoints leaks internal structure, creates circular references, and exposes sensitive data. Use response records instead.
