## Overview

This is a Next.js course-starter dashboard for viewing revenue, invoices, and customers, with invoice-management and login scaffolding. The visible workflow is dashboard or invoice/customer navigation, search and pagination through URL state, server-side data retrieval, and rendered tables or summaries. Invoice create/edit routes and action modules indicate mutation stages, though their implementations were not sampled; the login form is currently commented out. Edges reflect the sampled calls and SQL access, so some unsampled feature wiring is intentionally left unspecified.

Main entry points: [`app/dashboard/invoices/page.tsx`](https://github.com/rikhi9812/nextjs-dashboard/blob/main/app/dashboard/invoices/page.tsx) (Invoice listing), [`app/dashboard/page.tsx`](https://github.com/rikhi9812/nextjs-dashboard/blob/main/app/dashboard/page.tsx) (Dashboard page), [`app/lib/data.ts`](https://github.com/rikhi9812/nextjs-dashboard/blob/main/app/lib/data.ts) (Query and formatting), [`app/ui/dashboard/latest-invoices.tsx`](https://github.com/rikhi9812/nextjs-dashboard/blob/main/app/ui/dashboard/latest-invoices.tsx) (Latest invoices)
