Utiliser v0 : connexion v0.dev, prompt UI, export Next.js
Connexion v0.dev, UI par prompt, copie ou export Next.js.
v0 (Vercel) génère des interfaces dans le navigateur à partir d’un prompt, avec copie de code ou export vers Next.js.
Requête : utiliser v0 pour générer une UI et exporter vers Next.js. Selon v0.dev et la doc Vercel. Revue rapide : wbmeet, créer une salle.
À quoi sert v0
v0 outputs React snippets with Tailwind CSS and common shadcn/ui patterns—not a full CMS site. Use it for landing sections, dashboard cards, forms, and empty states. You get an interactive preview in v0; when satisfied, use Copy code or Vercel’s add to codebase / deploy entry (labels vary by UI) to land an App Router Next.js project. Credits and billing show in your v0/Vercel account.
Se connecter sur v0.dev
- 1
Open v0.dev
Visit
https://v0.dev(or the domain Vercel docs list today). Click Sign in / Log in—never sideload an “offline v0” bundle from unknown mirrors. - 2
Authenticate with Vercel
Use GitHub, Google, or email to sign into your Vercel account—the same identity you use to deploy Next.js. Team seats need permission; enterprise SSO follows admin policy.
- 3
Check credits and GitHub access
After login, read free-tier limits and daily generations on the account or pricing page (numbers change—trust the UI). If you plan GitHub export, stay signed into GitHub and approve the scopes Vercel/v0 request.
Premier bloc UI par prompt
- 1
Specify layout, states, and stack
Be concrete: “Responsive SaaS pricing table, three tiers, highlight middle column, Tailwind + shadcn Card, dark-mode friendly.” Mention empty/loading/error copy if needed. Avoid asking for twenty pages at once.
- 2
Iterate in the preview
v0 renders a clickable preview. Follow up with focused edits: “Use outline CTA,” “Stack to one column on mobile.” Change one concern per message so versions stay comparable.
- 3
Lock a version before export
Pick the preview you want, then copy or export. Click primary buttons and tabs in preview first; generated forms and a11y often need human follow-up.
Copier le code ou exporter Next.js
| Method | Best for | Watch for |
|---|---|---|
| Copy code | Existing Next/React repo | Align @/ aliases and tailwind.config |
| Add to codebase / Deploy (v0 labels vary) | New or linked Next.js on Vercel | Review app/ routes and dependencies |
| Split files manually | Large blocks → components/ | Fix imports and types |
# First hour · v0 · 2026-09
# 1. Sign in at https://v0.dev
# 2. Prompt: "Pricing table, 3 tiers, shadcn, responsive"
# 3. Iterate until preview OK
# 4. Copy → app/(marketing)/page.tsx
# OR v0 export to linked Next.js repo
# 5. npm install && npm run dev → QAPrompts should be testable
“Two columns desktop, one column mobile, primary #0b5cff” beats “make it prettier.”
Export ≠ production-ready
Verify aria-labels, focus order, and real API wiring—v0 gives a UI starting point.
Pair with IDE agents
v0 excels at UI blocks; wire logic and tests in Cursor, Continue, etc.—see our related notes.
Suggested flow: sign in at v0.dev → one small UI prompt → iterate in preview → copy or export Next.js →
npm run devlocally → optional huddle for stakeholder sign-off.
- Vs Cursor / Continue
- v0 is browser UI generation; local agents: Cursor CLI, Continue.
- Must deploy on Vercel?
- Copied code runs on any Next host; Vercel export is convenience, not a lock-in requirement.
- Not a meeting-product guide
- Only v0’s first hour. Short call: wbmeet.
Questions fréquentes
Can I use v0 without a Vercel account?
Official sign-in uses the Vercel identity system. Register with a real email or GitHub; credits follow v0’s account page.
Project errors after paste?
Often missing shadcn components or Tailwind plugins. Install deps from v0’s output notes; match @/ to tsconfig paths.
Non-Next project?
Yes, with import/route edits. React + Vite works; official export templates skew toward App Router.
GitHub blocked at work?
Use Copy code into an internal repo only. You may still need v0.dev access—follow IT policy.
