🔱 God Mode: Direct PostgreSQL Shim Architecture

Implementation Plan & Task List

Objective: Build a frontend that connects directly to PostgreSQL without going through Directus or traditional REST APIs, using server-side rendering (SSR) and a secure "shim" layer.

Architecture: Astro SSR + Direct PostgreSQL Pool + Secure API Routes

🔧 DETAILED EXAMPLE: Sites Table Implementation

Step 1: Type Definition (src/lib/shim/types.ts)

export interface Site {
  id: string;
  domain: string;
  status: 'active' | 'inactive' | 'pending';
  site_url: string;
  site_wpjson: string;
  created_at: Date;
  updated_at: Date;
}

export interface FilterOptions {
  limit?: number;
  offset?: number;
  status?: string;
  search?: string;
}

Step 2: Query Builder (src/lib/shim/sites.ts)

import { pool } from '@/lib/db';
import type { Site, FilterOptions } from './types';

export async function getSites(options: FilterOptions = {}): Promise<Site[]> {
  const { limit = 50, offset = 0, status, search } = options;
  
  let sql = 'SELECT * FROM sites WHERE 1=1';
  const params: any[] = [];
  let paramIndex = 1;
  
  if (status) {
    sql += ` AND status = $${paramIndex++}`;
    params.push(status);
  }
  
  if (search) {
    sql += ` AND domain ILIKE $${paramIndex++}`;
    params.push(`%${search}%`);
  }
  
  sql += ` ORDER BY created_at DESC LIMIT $${paramIndex++} OFFSET $${paramIndex++}`;
  params.push(limit, offset);
  
  const { rows } = await pool.query<Site>(sql, params);
  return rows;
}

export async function getSiteById(id: string): Promise<Site | null> {
  const { rows } = await pool.query<Site>(
    'SELECT * FROM sites WHERE id = $1',
    [id]
  );
  return rows[0] || null;
}

export async function createSite(data: Partial<Site>): Promise<Site> {
  const { rows } = await pool.query<Site>(
    `INSERT INTO sites (domain, status, site_url, site_wpjson)
     VALUES ($1, $2, $3, $4)
     RETURNING *`,
    [data.domain, data.status || 'pending', data.site_url, data.site_wpjson]
  );
  return rows[0];
}

export async function updateSite(id: string, data: Partial<Site>): Promise<Site> {
  const fields: string[] = [];
  const values: any[] = [];
  let paramIndex = 1;
  
  Object.entries(data).forEach(([key, value]) => {
    if (value !== undefined && key !== 'id') {
      fields.push(`${key} = $${paramIndex++}`);
      values.push(value);
    }
  });
  
  values.push(id);
  
  const { rows } = await pool.query<Site>(
    `UPDATE sites SET ${fields.join(', ')}, updated_at = NOW()
     WHERE id = $${paramIndex}
     RETURNING *`,
    values
  );
  return rows[0];
}

export async function deleteSite(id: string): Promise<boolean> {
  const result = await pool.query('DELETE FROM sites WHERE id = $1', [id]);
  return result.rowCount ? result.rowCount > 0 : false;
}

Step 3: API Route (src/pages/api/shim/sites/list.ts)

import type { APIRoute } from 'astro';
import { getSites } from '@/lib/shim/sites';

export const GET: APIRoute = async ({ request, url }) => {
  try {
    // 1. Token validation (optional for read operations)
    const token = request.headers.get('Authorization')?.replace('Bearer ', '');
    if (!token || token !== import.meta.env.GOD_MODE_TOKEN) {
      return new Response(JSON.stringify({ error: 'Unauthorized' }), {
        status: 401,
        headers: { 'Content-Type': 'application/json' }
      });
    }
    
    // 2. Parse query params
    const limit = parseInt(url.searchParams.get('limit') || '50');
    const offset = parseInt(url.searchParams.get('offset') || '0');
    const status = url.searchParams.get('status') || undefined;
    const search = url.searchParams.get('search') || undefined;
    
    // 3. Execute query
    const sites = await getSites({ limit, offset, status, search });
    
    // 4. Return JSON
    return new Response(JSON.stringify({ sites, count: sites.length }), {
      status: 200,
      headers: { 'Content-Type': 'application/json' }
    });
    
  } catch (error) {
    console.error('API Error:', error);
    return new Response(JSON.stringify({ error: 'Internal Server Error' }), {
      status: 500,
      headers: { 'Content-Type': 'application/json' }
    });
  }
};

Step 4: SSR Page (src/pages/shim/sites.astro)

---
import AdminLayout from '@/layouts/AdminLayout.astro';
import { getSites } from '@/lib/shim/sites';

// Server-side query - runs before HTML is sent
const sites = await getSites({ limit: 100 });
---

<AdminLayout title="Sites (Direct DB)">
  <h1 class="text-3xl font-bold text-white mb-4">Sites ({sites.length})</h1>
  
  <div class="space-y-2">
    {sites.map(site => (
      <div class="p-4 bg-slate-800 rounded-lg">
        <h3 class="text-white font-semibold">{site.domain}</h3>
        <p class="text-slate-400 text-sm">{site.site_url}</p>
        <span class={`text-xs px-2 py-1 rounded ${
          site.status === 'active' ? 'bg-green-500/20 text-green-400' : 'bg-gray-500/20 text-gray-400'
        }`}>
          {site.status}
        </span>
      </div>
    ))}
  </div>
</AdminLayout>

Step 5: React Component (src/components/shim/SitesList.tsx)

import React from 'react';
import { useQuery, useMutation, useQueryClient } from '@tanstack/react-query';
import type { Site } from '@/lib/shim/types';

export default function SitesList() {
  const queryClient = useQueryClient();
  
  const { data, isLoading } = useQuery({
    queryKey: ['shim-sites'],
    queryFn: async () => {
      const response = await fetch('/api/shim/sites/list', {
        headers: {
          'Authorization': `Bearer ${import.meta.env.PUBLIC_GOD_MODE_TOKEN}`
        }
      });
      return response.json();
    }
  });
  
  const deleteMutation = useMutation({
    mutationFn: async (id: string) => {
      await fetch(`/api/shim/sites/${id}`, {
        method: 'DELETE',
        headers: {
          'Authorization': `Bearer ${import.meta.env.PUBLIC_GOD_MODE_TOKEN}`
        }
      });
    },
    onSuccess: () => {
      queryClient.invalidateQueries({ queryKey: ['shim-sites'] });
    }
  });
  
  if (isLoading) return <div>Loading...</div>;
  
  return (
    <div className="space-y-2">
      {data?.sites?.map((site: Site) => (
        <div key={site.id} className="p-4 bg-slate-800 rounded-lg flex justify-between items-center">
          <div>
            <h3 className="text-white font-semibold">{site.domain}</h3>
            <p className="text-slate-400 text-sm">{site.site_url}</p>
          </div>
          <button
            onClick={() => deleteMutation.mutate(site.id)}
            className="px-3 py-1 bg-red-600 text-white rounded hover:bg-red-700"
          >
            Delete
          </button>
        </div>
      ))}
    </div>
  );
}

---

🔒 SECURITY CHECKLIST

• Never expose DATABASE_URL to client-side code
• Always validate tokens in API routes
• Always use parameterized queries ($1, $2) - never string concatenation
• Never trust user input - sanitize before queries
• Use connection pooling (already in db.ts)
• Limit query results (default LIMIT 50)
• Log all database errors server-side
• Test for SQL injection vulnerabilities

---

🚀 DEPLOYMENT CHECKLIST

• Set DATABASE_URL environment variable in Coolify
• Set GOD_MODE_TOKEN for API authentication
• Verify Dockerfile builds with pg dependency
• Test connection pool limits under load
• Monitor database connection count
• Set up database backups
• Configure SSL for PostgreSQL connection (production)

📊 EXPECTED PERFORMANCE

Operation	SSR (Server-Side)	API Route (Client-Side)
Get 50 sites	~10ms	~50ms (includes HTTP)
Create site	~15ms	~60ms
Update site	~12ms	~55ms
Complex join	~50ms	~100ms

Why SSR is faster: No HTTP roundtrip, query executes before HTML is sent.

---

🎯 SUCCESS CRITERIA

1. ✅ Can view sites list on /shim/sites without any client-side API calls
2. ✅ Can create/update/delete sites via React component using /api/shim/sites/*
3. ✅ No database credentials visible in browser DevTools
4. ✅ All queries use parameterized SQL (no injection risk)
5. ✅ Connection pool stays under 20 connections
6. ✅ Token validation works on all API endpoints
7. ✅ SSR pages load in < 100ms with 1000+ records
