Tempo

Tempo now defaults to the Go-backed SSR/SSE runtime. The previous vanilla JS + localStorage demo is still available as a frozen fallback under /local/.

Run

go run -mod=mod ./cmd/tempo -addr :8080

Open http://localhost:8080. The server seeds SQLite on first boot and stores data in tempo.db unless you pass another DSN. Use -reset after demo schema or fixture changes when you want the current seed, including reporting lines.

Useful flags and matching env vars:

Flag	Env	Default	Notes
-addr	TEMPO_ADDR	:8080	HTTP listen address
-db-driver	TEMPO_DB_DRIVER	sqlite	sqlite or mysql
-dsn	TEMPO_DSN	SQLite tempo.db	Driver-specific DSN
-assets-dir	TEMPO_ASSETS_DIR	.	Directory with CSS/JS/assets
-tz	TEMPO_TZ	local time	Business timezone
-reset	TEMPO_RESET	false	Reseed data on boot

SQLite uses the CGO-free modernc.org/sqlite driver. MySQL uses github.com/go-sql-driver/mysql:

TEMPO_DB_DRIVER=mysql TEMPO_DSN='user:pass@tcp(localhost:3306)/tempo?parseTime=true' \
	go run -mod=mod ./cmd/tempo

Validate

This repo has a non-Go vendor/ folder, so use -mod=mod unless you later sync a real Go vendor tree.

go test -mod=mod ./...
go test -mod=mod -bench=. -benchmem ./...

Runtime shape

• Real SSR routes: /, /wall, /who/{employeeID}, /shifts, /requests, /operations, /admin.
• Patch navigation: the browser requests server-rendered patch envelopes and applies them through Tempo.patch.
• SSE: /events sends connection-scoped snapshots; the server renders each connected session with that session's identity, filters, tabs, theme, and permissions.
• Local fallback: /local/ serves the old static/localStorage app.

Seeded demo data

The Go runtime seeds a thick SAMA/ATL operations fixture:

• Metros: SAMA and ATL.
• Teams: SAMA has SN/SAT Site Services and Logistics; ATL has Site Services and Logistics.
• Shifts: A/B Side Days and Nights, 12-hour 7-to-7 schedules on a two-week complement cycle.
• Staffing: every team+shift has two managers; each manager seeds two seniors and twelve techs.
• Org chart: manager scope is based on direct reports/reporting subtree, not the whole team. Ops Cross-team is the intentional full-visibility exception.
• Demo login convention: each seeded employee has name@tempo.demo; the shared demo password is Password123.
