# Vercel Deployment
Turborepo integrates seamlessly with Vercel for monorepo deployments.
## Remote Cache
Remote caching is **automatically enabled** when deploying to Vercel. No configuration needed - Vercel detects Turborepo and enables caching.
This means:
- No `TURBO_TOKEN` or `TURBO_TEAM` setup required on Vercel
- Cache is shared across all deployments
- Preview and production builds benefit from cache
## turbo-ignore
Skip unnecessary builds when a package hasn't changed using `turbo-ignore`.
### Installation
```bash
npx turbo-ignore
```
Or install globally in your project:
```bash
pnpm add -D turbo-ignore
```
### Setup in Vercel
1. Go to your project in Vercel Dashboard
2. Navigate to Settings > Git > Ignored Build Step
3. Select "Custom" and enter:
```bash
npx turbo-ignore
```
### How It Works
`turbo-ignore` checks if the current package (or its dependencies) changed since the last successful deployment:
1. Compares current commit to last deployed commit
2. Uses Turborepo's dependency graph
3. Returns exit code 0 (skip) if no changes
4. Returns exit code 1 (build) if changes detected
### Options
```bash
# Check specific package
npx turbo-ignore web
# Use specific comparison ref
npx turbo-ignore --fallback=HEAD~1
# Verbose output
npx turbo-ignore --verbose
```
## Environment Variables
Set environment variables in Vercel Dashboard:
1. Go to Project Settings > Environment Variables
2. Add variables for each environment (Production, Preview, Development)
Common variables:
- `DATABASE_URL`
- `API_KEY`
- Package-specific config
## Monorepo Root Directory
For monorepos, set the root directory in Vercel:
1. Project Settings > General > Root Directory
2. Set to the package path (e.g., `apps/web`)
Vercel automatically:
- Installs dependencies from monorepo root
- Runs build from the package directory
- Detects framework settings
## Build Command
Vercel auto-detects `turbo run build` when `turbo.json` exists at root.
Override if needed:
```bash
turbo run build --filter=web
```
Or for production-only optimizations:
```bash
turbo run build --filter=web --env-mode=strict
```
