Phase 17 Plan 01: Docker Deployment Prep Summary

Standalone Next.js output, Neon pool cap at 5, @vercel/blob removal, and public GET /api/health endpoint with SELECT 1 DB check

Performance

• Duration: 2 min
• Started: 2026-04-03T22:52:56Z
• Completed: 2026-04-03T22:53:49Z
• Tasks: 2
• Files modified: 4

Accomplishments

• Added output: 'standalone' to next.config.ts (prerequisite for Dockerfile three-stage build)
• Limited Neon postgres pool to max: 5 in src/lib/db/index.ts to prevent connection exhaustion on free tier
• Removed dead @vercel/blob dependency (7 packages removed, confirmed not imported anywhere in src/)
• Created GET /api/health at src/app/api/health/route.ts — runs SELECT 1 via Drizzle, returns 200 or 503

Task Commits

Each task was committed atomically:

1. Task 1: Enable standalone output, limit DB pool, remove @vercel/blob - fa7d6a9 (feat)
2. Task 2: Create /api/health endpoint with DB connectivity check - 57326d7 (feat)

Files Created/Modified

• teressa-copeland-homes/next.config.ts - Added output: 'standalone'; kept existing transpilePackages and serverExternalPackages
• teressa-copeland-homes/src/lib/db/index.ts - Changed postgres(url) to postgres(url, { max: 5 })
• teressa-copeland-homes/package.json - Removed @vercel/blob: ^2.3.1 from dependencies
• teressa-copeland-homes/src/app/api/health/route.ts - New public GET endpoint, SELECT 1 via Drizzle, 200/503 response

Decisions Made

• Health endpoint is intentionally public (no auth import, no session check) so Docker HEALTHCHECK can reach it without credentials
• Kept transpilePackages and serverExternalPackages intact in next.config.ts per plan spec

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None — TypeScript compiled clean (npx tsc --noEmit passed with no output).

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Plan 17-02 (Dockerfile, docker-compose.yml, .dockerignore, .env.production.example) can proceed immediately
• All code-level prerequisites for the Docker build are now in place
• Dockerfile builder stage will find output: 'standalone' in next.config.ts
• docker-compose.yml HEALTHCHECK can target http://localhost:3000/api/health
