# Build script for Vercel deployment of @objectstack/server.
#
# Follows the Vercel deployment pattern:
#   - api/[[...route]].js is committed to the repo (Vercel detects it pre-build)
#   - esbuild bundles server/index.ts → api/_handler.js (self-contained bundle)
#   - The committed .js wrapper re-exports from _handler.js at runtime
#   - Studio SPA is built and copied to public/ for serving the UI
#
# Steps:
#   1. Build the project with turbo (includes studio)
#   2. Bundle the API serverless function (→ api/_handler.js)
#   3. Copy studio dist files to public/ for UI serving
