Overview

PreachPro is a full-stack ministry SaaS application focused on sermon preparation and pastoral operations. The frontend provides a rich authoring and planning experience, while Supabase-backed services handle authentication, data, AI workflows, and billing operations.

Core Features

• AI biblical scholar and sermon assistance workflows
• Advanced sermon editor and presentation/preaching mode
• Sermon analysis and transcription flows
• Ministry management modules (contacts, prayer requests, tasks, events)
• Calendar and productivity tooling
• Subscription and checkout flows with Stripe
• Admin management capabilities and support/contact email flows

Architecture

• Frontend: React + TypeScript SPA built with Vite, routed with React Router
• UI layer: Tailwind CSS, Radix UI primitives, and shadcn-style component patterns
• State/Data: TanStack Query for server state, additional client state stores where needed
• Backend: Supabase (Auth, Postgres, storage, edge/serverless functions)
• Serverless logic: Supabase Edge Functions (TypeScript on Deno) for AI calls, billing, notifications, and automation
• Integrations: OpenAI for AI features, Stripe for subscriptions/payments, email service integrations for transactional flows

Implementation Notes

The project is structured as a production-grade web app with a modular src/ frontend and extensive supabase/functions/ backend handlers. It emphasizes secure auth gating (JWT checks per function category), subscription lifecycle handling, and ministry-specific workflows tailored to sermon prep and church operations.
