Work Summary — 2026-08-03 23:58

Task

Add a Makefile with a make dev target: apply pending DB migrations, start the Tailwind watcher, and run the server, all from one command.

Context

User pushed back on the initial framing ("I can already start the server with go run .") — fair, since that part was never the friction. The real friction, confirmed via .zsh_history, is the other two steps done by hand around it: the migrate CLI invoked with its full DSN spelled out literally ~10 times over recent weeks (migrate -path database_migrations -database "postgres://app_client:app_password@localhost:5432/inventory_2?sslmode=disable" up 1), and tailwind.sh (which already runs --watch) needing to be started manually in a separate terminal — easy to forget, leading to template/CSS changes silently not showing up. Framed the Makefile's value around removing those two specific manual steps, not around wrapping go run ..

Changes

• New Makefile at repo root:
  • -include .env + export so DATABASE_URL (and everything else in .env) is available to recipes without hand-typing it — fixes the DSN-drift risk where the hand-typed migrate command could silently diverge from what's actually in .env.
  • dev (default goal): depends on migrate-up, then backgrounds ./tailwind.sh, captures its PID, sets a trap to kill it on EXIT/INT/TERM, then runs go run . in the foreground. Ctrl-C (or any termination) stops both cleanly.
  • migrate-up / migrate-down / migrate-version: thin wrappers around the migrate CLI using $(DATABASE_URL), so the DSN is typed once (in .env) instead of per-invocation.
  • tailwind: one-shot alias for ./tailwind.sh (still watch mode, matching existing script behavior).
  • run: plain go run ., for when you don't want migrations/CSS touched.

Verification

• make migrate-version / make migrate-up — ran cleanly against the real local DB (idempotent: reported "no change" since already at the latest migration).
• make dev under a timeout — confirmed via log output that migrations ran, Tailwind's watcher started (tailwindcss v4.1.18 banner), the server bound and served a 200 on /ui, and on SIGTERM both the server and the Tailwind watcher shut down (verified no leftover tailwindcss/npx process survived — first check was a pgrep self-match false positive on the search string appearing in the invoking shell's own command line, re-verified cleanly with ps aux).

Incident during verification (self-caused, fixed)

Killing make dev mid-run once truncated the committed styles/index.css to empty (1370 lines → 0) — the Tailwind watcher was killed while mid-write on its first build. Caught it in the post-test git status/git diff review before finishing; restored via git checkout -- styles/index.css. Worth knowing for next time: killing the watcher while it's actively writing that file is a real (if narrow) way to corrupt a tracked file — not something make dev itself introduces (same risk exists running tailwind.sh directly), but noting it here since it's the kind of thing to double check after using this target.

Follow-ups / not done here

• Next planned step per the dev-iteration plan: broaden test coverage beyond server/ui/charts/*_test.go (nothing currently covers domains/accounts, domains/reports, domains/raw_events, or the Amazon mock pipeline).
