#Deployment

#Build pipeline

All deployments go through CI:

1. Lint and typecheck — pnpm check
2. Test — pnpm test
3. Build — pnpm build
4. Deploy — platform-specific deploy step

#Web (Vercel)

The web app deploys to Vercel on push to main:

# Build command
pnpm --filter web build

# Output directory
apps/web/.next

Environment variables are managed in the Vercel dashboard.

#API (Railway)

The API deploys to Railway:

# Build command
pnpm --filter api build

# Start command
node apps/api/dist/index.js

#Database migrations

Migrations run automatically in CI before deployment:

pnpm --filter db migrate

Migrations are never run directly in production. Always go through the CI pipeline.

#Rollback

Both Vercel and Railway support instant rollbacks to the previous deployment. No code changes required.
