Partial analysis: some checks could not run on this component.

scanner score 7/100

SkillSpector looks for patterns such as shell commands, credential access, network calls or unpinned dependencies. An observation is something worth reading in the files before you install, not a confirmed vulnerability. Components that run code locally, like hooks, MCP servers and security tooling, naturally show more of them.

Work Process

Authentication Analysis

bash

grep -r "useUser\|StackProvider\|neon_auth" . --include="*.tsx" --include="*.ts"
find . -name "stack.ts" -o -name "*auth*" -o -path "*/handler/*"

Implementation Focus
- Set up Stack Auth with Neon Auth integration
- Configure user management workflows
- Implement secure authentication patterns
- Handle user data synchronization

Response Format

🔐 AUTHENTICATION SETUP

## Current State
- Auth system: [Stack Auth status]
- Database sync: [Neon Auth status]

## Implementation
1. [Stack Auth setup]
2. [Database schema creation]
3. [User management integration]

## Security Checklist
- [ ] Environment variables secured
- [ ] User data sync working
- [ ] Auth flows tested

Stack Auth Setup

Initial Installation

bash

npx @stackframe/init-stack@latest

Environment Configuration

env

NEXT_PUBLIC_STACK_PROJECT_ID=your_project_id
NEXT_PUBLIC_STACK_PUBLISHABLE_CLIENT_KEY=your_client_key
STACK_SECRET_SERVER_KEY=your_server_key
DATABASE_URL=your_neon_connection_string

Basic Integration

tsx

// app/layout.tsx
import { StackProvider, StackTheme } from "@stackframe/stack";
import { stackServerApp } from "@/stack";

export default function RootLayout({ children }: { children: React.ReactNode }) {
  return (
    <html>
      <body>
        <StackProvider app={stackServerApp}>
          <StackTheme>
            {children}
          </StackTheme>
        </StackProvider>
      </body>
    </html>
  );
}

Neon Auth Database Schema

sql

-- Neon Auth automatically creates this schema
CREATE SCHEMA IF NOT EXISTS neon_auth;

CREATE TABLE neon_auth.users_sync (
    raw_json JSONB NOT NULL,
    id TEXT NOT NULL,
    name TEXT,
    email TEXT,
    created_at TIMESTAMP WITH TIME ZONE,
    deleted_at TIMESTAMP WITH TIME ZONE,
    PRIMARY KEY (id)
);

CREATE INDEX users_sync_deleted_at_idx ON neon_auth.users_sync (deleted_at);

User Management Components

tsx

// Client Component
"use client";
import { useUser } from "@stackframe/stack";

export function UserProfile() {
  const user = useUser({ or: "redirect" });

  return (
    <div>
      <h1>Welcome, {user.displayName}</h1>
      <p>Email: {user.primaryEmail}</p>
      <button onClick={() => user.signOut()}>Sign Out</button>
    </div>
  );
}

tsx

// Server Component
import { stackServerApp } from "@/stack";

export default async function ProtectedPage() {
  const user = await stackServerApp.getUser({ or: "redirect" });

  return <div>Hello, {user.displayName}</div>;
}

Database Integration Patterns

sql

-- Joining user data with application tables
SELECT
  t.*,
  u.name AS user_name,
  u.email AS user_email
FROM
  public.todos t
LEFT JOIN
  neon_auth.users_sync u ON t.user_id = u.id
WHERE
  u.deleted_at IS NULL
  AND t.user_id = $1;

Security Best Practices

Always filter out deleted users: WHERE deleted_at IS NULL
Use LEFT JOIN when relating to neon_auth.users_sync
Never create foreign keys to the auth schema
Handle user deletion gracefully in application logic
Validate user permissions on every protected operation

Page Protection Middleware

tsx

// middleware.ts
import { stackServerApp } from "@/stack";
import { NextRequest, NextResponse } from "next/server";

export async function middleware(request: NextRequest) {
  const user = await stackServerApp.getUser();

  if (!user && request.nextUrl.pathname.startsWith("/protected")) {
    return NextResponse.redirect(new URL("/handler/sign-in", request.url));
  }

  return NextResponse.next();
}

export const config = {
  matcher: ["/protected/:path*", "/dashboard/:path*"]
};
