Next.js App Router

@sudomimus/nextjs provides server route handlers for login, callback, logout, and current-session access.

Wire the handlers

Create one server-only module with your Connect options and a shared durable WebAuthStore:

src/lib/sudomimus.ts

import { createNextHandlers } from "@sudomimus/nextjs";

export const {
    start,
    callback,
    logout,
    current,
    currentFromCookieHeader,
} = createNextHandlers(options);

Export those handlers from App Router route files:

app/api/login/route.ts

export { start as POST } from "@/lib/sudomimus";

// app/auth/callback/route.ts
export { callback as GET } from "@/lib/sudomimus";

// app/api/logout/route.ts
export { logout as POST } from "@/lib/sudomimus";

Call current(request) in a Route Handler. In a Server Component, pass the request cookie header to currentFromCookieHeader. Never pass returned tokens into a Client Component.

The POST handlers validate Origin against the callback origin. Keep them as POST endpoints and configure a CALLBACK ReturnRule for the exact callback URL.
