Function getContext

getContext(req: NextRequest): Context
Builds the auth context from a NextRequest: reads either the Authorization: Bearer <token> header or the refresh cookie. Use this in REST API routes (outside GraphQL) to identify the current user.

The GraphQL server uses this automatically — you typically only need it for custom REST endpoints.
Parameters
- req: NextRequest
  The NextRequest (headers and cookies are read).
Returns Context
Context with userId: number | null. If the user was identified via the refresh cookie (not an access token), isRefreshID is set to true.
Example
```
import { getContext } from "naystack/auth";

export const POST = async (req: NextRequest) => {
  const ctx = getContext(req);
  if (!ctx?.userId) return new NextResponse("Unauthorized", { status: 401 });
  // ctx.userId is the authenticated user's id
};
```
