PRD for Next.js project: How to write one your devs will follow
This page explains what makes a production-ready PRD for your Next.js project using App Router, React Server Components, and deploying to Vercel. You'll get a real filled PRD example, tool and methodology comparisons, and a step-by-step how-to for structuring documentation your team won't ignore. Expect specifics.
What this is
A PRD for Next.js project is a Product Requirements Document written to guide cross-functional teams building on Next.js (especially with the App Router and Server/Client Component split) and deploying to Vercel. It's tailored to development in Next.js, with explicit notes on code placement, database integration (e.g., Postgres via Drizzle or Prisma), RSC boundaries, and performance targets. Used alongside tools like Vercel Preview Deployments and Drizzle ORM, the PRD ensures devs deliver features as intended—on time and to spec.
Compared to alternatives
| Option | Best for | Trade-off |
|---|---|---|
| Notion for PRDs | Quick iteration and async teams | Search and structure gets messy; can lack code context |
| Markdown in GitHub repo | Keeping PRDs versioned with code | Non-tech stakeholders may get lost in PR branches |
| Linear Specs | Integrating tasks and requirements tightly | Can't model the complexity of Next.js RSC split easily |
| v0 app builder | Rapid prototyping UI for Next.js | Generated code still needs PRD-level business context, not just Figma to code |
| Cursor or Lovable | AI-assisted spec-to-design | Abstracts too far for nuanced Next.js infra choices |
A real example
Product Requirements Document: Next.js Customer Feedback App
Overview: We're building 'Feedbackly', a customer feedback tool for SaaS sites. Users can leave feedback on any page. Admins view, tag, and resolve issues. Goal: MVP deployed in 3 weeks, supporting 1,000 DAU, <500ms median page load on Vercel.
Target Stack:
- Next.js (App Router, TypeScript)
- React Server Components (RSC split for feedback list, Client Components for input forms/modals)
- Database: Postgres (via Drizzle ORM)
- Deployed to Vercel (Production + Preview Deployments)
- Auth: Clerk (social, email login)
Core User Stories:
- As a visitor, I can open the feedback widget from any page (Client Component)
- As a user, I submit 250 characters feedback; gets stored instantly (optimistic UI)
- As an admin, I see real-time list of feedback (RSC)
- As an admin, I can tag feedback and mark status (resolved, in-progress)
Key Requirements:
- RSC/Client split:
- All listing and admin views are Server Components
- Widget and input forms are Client Components, hydrated only when opened
- DB Integration:
- Use Drizzle's TypeScript ORM with Postgres (Supabase-compatible)
- Migrations tracked in repo; schema must allow for rich feedback, user, status tables
- Deploy:
- Vercel; preview on each PR
- Production target: 99.9% uptime, <1s worst-case SSR latency
Analytics:
- Track widget opens/submits (Vercel Analytics, custom events)
- SLA: ship MVP within 21 days, support 40% faster admin triaging vs. competitor baseline
Out of Scope:
- SSO for enterprise; export to CSV
Risks/Contingencies:
- If Drizzle migration fails, fallback to Prisma
Links:
- Figma: [Widget UI v2]
- GitHub: [feedbackly-app repo]
How to use this
- Clarify Next.js-specific architecture: Explicitly define which features require Server Components (e.g., admin dashboards, DB queries) and which live as Client Components (e.g., modals, forms). Call out hydration strategy early so devs don’t misplace logic.
- Specify database approach: Choose (and name) your ORM and DB, e.g. Drizzle or Prisma with Postgres. State where migrations live and how schema evolves in the repo. Highlight if you’re using Vercel Postgres or external managed DB.
- Declare Vercel deployment details: Write acceptance criteria for Vercel: required preview branches, production URLs, performance SLAs. Mention critical env vars or secrets needed at deploy, like NEXT_PUBLIC endpoints.
- Write detailed user stories: For each user type (visitor, admin), list stories with acceptance criteria tied to a UI surface or API endpoint—always include a metric (response time, DAU target, etc).
- Flag out-of-scope items and risks: List what you’re intentionally not building (e.g., no mobile app yet), and what could derail you (e.g., ORM migration pain). Being honest here shows devs you know the quirks.
- Link relevant artifacts: Include Figma files, GitHub repo, database ERD, and any competitor benchmarks to ground requirements in reality.
FAQ
How do I structure a PRD for a Next.js repo?
Place the PRD as a Markdown file in the repo's root or a /docs directory. Include clear sections for RSC vs Client Components, database connectivity (e.g., Prisma, Drizzle), user stories, edge cases, and Vercel-specific deploy notes.
What's the best way to handle database migrations in Next.js on Vercel?
Use migration tools provided by your ORM (like Drizzle Kit or Prisma Migrate), and commit migration scripts to your repo. For Vercel, ensure migrations run before build, or consider CI/CD scripts. Always document migration commands in your PRD.
Why call out Server vs Client Components in the PRD?
Next.js (App Router) splits Server and Client Components for bundling and performance. Being explicit avoids confusion—without this, devs may implement features in the wrong layer, leading to hydration errors or slow UX.
Can I use Supabase with Drizzle or Prisma in my Next.js project?
Yes. Both Drizzle and Prisma can connect to Supabase Postgres. Just note any connection string or authentication quirks in your PRD. Supabase simplifies auth and storage if you want to avoid wiring up those parts yourself.
