Vercel Deploy Preview

Overview

Deploy preview environments for branches and pull requests. Every git push to a non-production branch generates a unique preview URL. Covers CLI-based previews, API-based previews, deployment protection, and comment integration.

Prerequisites

• Completed vercel-install-auth setup
• Project linked via vercel link
• Git repository connected in Vercel dashboard

Instructions

Step 1: Deploy Preview via CLI

# Deploy current directory to a preview URL (default — not --prod)
vercel

# Output:
# 🔗 Linked to your-team/my-app
# 🔍 Inspect: https://vercel.com/your-team/my-app/AbCdEfG
# ✅ Preview: https://my-app-git-feature-branch-your-team.vercel.app

# Deploy a specific directory
vercel ./dist

# Deploy and wait for build to complete (useful in CI)
vercel --no-wait  # returns immediately with deployment URL

Step 2: Deploy Preview via REST API

# Create a deployment via API — useful for custom CI pipelines
curl -X POST "https://api.vercel.com/v13/deployments" \
  -H "Authorization: Bearer $VERCEL_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "my-app",
    "target": "preview",
    "gitSource": {
      "type": "github",
      "repoId": "123456789",
      "ref": "feature/new-feature",
      "sha": "abc123def456"
    }
  }'

Step 3: Check Deployment Status

# Poll deployment status until READY
curl -s -H "Authorization: Bearer $VERCEL_TOKEN" \
  "https://api.vercel.com/v13/deployments/dpl_xxxxxxxxxxxx" \
  | jq '{state: .state, url: .url, readyState: .readyState}'

# States: QUEUED → BUILDING → READY (or ERROR/CANCELED)

// Programmatic polling
async  () {
   () {
     d =  client.(deploymentId);
     (d. === )  d;
     (d. ===  || d. === ) {
        ();
    }
      ( (r, )); 
  }
}
