Setting up CI/CD workflows for V0-generated apps

Why V0 projects need CI/CD workflows

V0's built-in publish feature deploys directly from the editor, but it skips essential quality gates: no linting, no type checking, no automated tests, and no PR review. When you export to GitHub and deploy via Vercel, you gain the ability to add these checks. V0 auto-commits to a branch (v0/main-abc123) and creates PRs, which is the perfect trigger for CI pipelines. Without CI/CD, V0's auto-generated code — which often has TypeScript errors, missing type definitions, and shadcn registry mismatches — goes directly to production. A proper pipeline catches these issues before they reach users.

• V0's built-in deploy skips linting, type checking, and testing — code goes straight to production
• V0 auto-commits frequently, and each commit could introduce build-breaking changes
• Exported code often has TypeScript errors that only surface during a full build
• No automated way to prevent V0 from deploying broken code without CI checks
• Team members need visibility into V0's changes before they reach the main branch

Error messages you might see

Before you start

• A V0 project connected to GitHub via the Git panel
• A Vercel account connected to the GitHub repository
• Basic understanding of GitHub Actions YAML syntax

Best practices to prevent this

• Run lint, type check, and build as minimum CI checks on every V0 PR before allowing merge
• Use Vercel's GitHub integration for automatic preview deployments on every PR
• Set branch protection on main requiring status checks to pass and at least one review approval
• Add environment variables in both GitHub Actions secrets (for CI) and Vercel dashboard (for deployment)
• Label V0-generated PRs automatically so team members can identify and prioritize review
• Use squash merge for V0 PRs to keep main branch history clean
• Add a Vercel preview comment bot so reviewers can test the deployment directly from the PR
