Stop Reinventing
Backend Architecture
Every new Next.js + Supabase + Stripe client project starts with the same boilerplate, and the same AI-generated bugs. DevVault gives your team production-ready RLS schemas, Stripe webhook handlers, and context-tuned .cursorrules so Cursor and Claude stop hallucinating deprecated patterns on every new build.
// .cursorrules - Next.js 14 App Router & TypeScript
- Always favor Server Components over Client Components.
- Use explicit return types on all server actions and route handlers.
- Strictly type @supabase/ssr cookie stores with Parameters<typeof cookieStore.set>[2].
- Implement strict error boundaries on all external API integrations.Context-Aware Cursor Rules
Stop LLMs from suggesting outdated App Router patterns, invalid Supabase client instantiation, or bad state management. Our curated .cursorrules dictate exact project structure and typing rules.
Supabase SSR & RLS
Pre-configured cookie handling for Next.js Server Components, Server Actions, and Route Handlers alongside field-tested database security policies.
Stripe Sync Engine
Robust webhook integration for handling recurring subscriptions, cancellations, failed payments, and customer portal redirects.
Plug-and-Play Integration
Copy exact code snippets directly into your existing Next.js repositories without needing to rewrite your database layer or alter existing frontends.
