version: "1.0.1" name: scaffold-nextjs description: Scaffolds a production-ready Next.js turborepo end to end. Runs create-next-app with TypeScript, Tailwind CSS, and React Compiler, sets up shadcn/ui with Blode UI components from the ui.blode.co registry, blode-icons-react icons, Agentation, and Ultracite (Oxlint, Oxfmt, Lefthook), converts the app into a turborepo, then creates the GitHub repo and deploys to Vercel with a pre-launch checklist. Use when creating a brand-new Next.js app, bootstrapping a turborepo, scaffolding a web project, starting a new repo for a website or marketing site, or asking "create a Next.js project", "set up a turborepo", or "start a new web app". For a TypeScript CLI or npm package, use scaffold-cli. For folder structure and module contracts in an existing app, use define-architecture. For building a page inside an existing app, visual direction, palettes, and theming, use ui-design.

Scaffold Next.js

Scaffold a Next.js turborepo with full tooling, GitHub, and Vercel deployment.

• IS: bootstrapping a brand-new Next.js turborepo end to end: app creation, Blode UI, Ultracite tooling, turborepo conversion, GitHub, and Vercel.
• IS NOT: scaffolding a TypeScript CLI or npm package (use scaffold-cli), designing folder structure or module contracts for an existing app (use define-architecture), building a page inside an existing app, or choosing visual direction and palettes (use ui-design).

Low-freedom workflow. The reference files are the single source of truth for commands: run them as written, in phase order. Do not reconstruct commands from memory.

Scaffold Workflow

Copy this checklist to track progress:

Scaffold progress:
- [ ] Phase 1: Gather project info
- [ ] Phase 2: Create Next.js app
- [ ] Phase 3: Install Blode UI components
- [ ] Phase 4: Install Agentation
- [ ] Phase 5: Install Ultracite
- [ ] Phase 6: Convert to Turborepo
- [ ] Phase 7: GitHub and Vercel setup
- [ ] Phase 8: Pre-launch checklist
- [ ] Validation: run the checklist in deploy-and-launch.md

Phase 1: Gather project info

Collect from the user (ask only for what is missing):

Phase 2: Create Next.js app

Run the create-next-app command from references/app-setup.md exactly as written (it pins linter, React Compiler, and package-manager flags). Confirm the app loads at http://localhost:3000 before continuing.

Phase 3: Install Blode UI components

Blode UI section of references/app-setup.md: shadcn init, register the @blode namespace, then add components. Registration must precede any add @blode/... call. Use blode-icons-react for icon imports, never lucide-react.

Phase 4: Install Agentation

Agentation section of references/app-setup.md: install the package, patch app/layout.tsx with the dev-only <Agentation /> guard. Optionally add Google Analytics via @next/third-parties.

Phase 5: Install Ultracite

Ultracite section of references/app-setup.md: delete the Biome placeholder config, run ultracite init with the exact flags listed, then verify with npx ultracite fix and npx ultracite check.

Phase 6: Convert to Turborepo

Move the app into apps/web/ (commands at the end of references/app-setup.md), then from references/turbo-configs.md:

1. Generate root package.json, turbo.json, knip.json, and .gitignore from the templates.
2. Update apps/web/package.json scripts to the turbo-compatible block.
3. Verify apps/web/next.config.ts has reactCompiler: true.
4. Run npm install from the root.
5. Verify npm run dev works from the root (turbo runs apps/web).

Phase 7: GitHub and Vercel setup

From references/deploy-and-launch.md: create the GitHub repo with gh, deploy to Vercel, attach {{domain}}.

Phase 8: Pre-launch checklist

Favicon and OG image steps in references/deploy-and-launch.md, then run the validation checklist at the end of that file. Done only when every validation item passes; "the site loads" is not sufficient evidence.

Placeholder Reference

Templates use {{variable}} syntax. Before Phase 7, sweep for missed placeholders:

grep -rn '{{' --include='*.json' --include='*.ts' --include='*.tsx' --include='*.md' .

A {{name}} left in package.json fails npm install (invalid-name error); a {{domain}} left in metadata ships broken OG URLs.

Gotchas

• No src/ directory. The scaffold uses --no-src-dir; adding src/ later breaks the @/* alias and every shadcn component path.
• No ESLint or Prettier. Ultracite owns lint and format via Oxlint + Oxfmt; a stray .eslintrc makes the editor disagree with the lefthook pre-commit hook.
• Never run oxlint or oxfmt ad hoc; use npx ultracite fix / npx ultracite check (or root npm run fix / npm run check) so config resolution matches the hook. The oxlint . / oxfmt . scripts in apps/web/package.json exist only for turbo's per-workspace orchestration.
• No manual git hooks. ultracite init writes lefthook.yml and a prepare: lefthook install script; husky or another hook manager double-runs or skips fixes.
• No app dependencies in the root package.json (root holds only turbo and ultracite); they break workspace isolation and turbo cache keys.
• Never run npx shadcn@latest add @blode/... before npx shadcn@latest registry add @blode=...; the unregistered namespace makes the add fail.
• Never import from lucide-react; blode-icons-react is Blode UI's icon library and mixed imports bundle two icon sets. Replace any generated lucide-react import paths.
• Never create apps/web/ by hand. Scaffold at the root first, then move it in Phase 6; hand-building skips create-next-app defaults (Tailwind wiring, alias config).
• Check the Vercel Root Directory before dashboard deploys. On a 404 or wrong app, set Root Directory to apps/web in Settings > General.
