# Build script for Vercel deployment of @objectstack/studio.
#
# Follows the same Vercel deployment pattern as hotcrm:
#   - 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
#   - Vite SPA output is copied to public/ for CDN serving
#
# Vercel routing (framework: null, no outputDirectory):
#   - Static files:        served from public/
#   - Serverless functions: detected from api/ at project root
#
# Steps:
#   1. Turbo build (Vite SPA → dist/)
#   2. Bundle the API serverless function (→ api/_handler.js)
#   3. Copy Vite output to public/ for Vercel CDN serving

# 1. Build the studio SPA with turbo (from monorepo root)
cd ../..
pnpm turbo run build --filter=@objectstack/studio
cd apps/studio

# 2. Bundle API serverless function
node scripts/bundle-api.mjs

# 3. Copy native/external modules into local node_modules for Vercel packaging.
#
#    Unlike hotcrm (which uses shamefully-hoist=true), this monorepo uses pnpm's
#    default strict node_modules structure. Transitive native dependencies like
#    better-sqlite3 only exist in the monorepo root's node_modules/.pnpm/ virtual
#    store — they're NOT symlinked into apps/studio/node_modules/.
#
#    The vercel.json includeFiles pattern references node_modules/ relative to
#    apps/studio/, so we must copy the actual module files here for Vercel to
#    include them in the serverless function's deployment package.
#
#    Note: @libsql/client is now bundled by esbuild, so we no longer copy it.
