zeitkort-web-only POC

A self-contained web-only proof-of-concept version of zeitkort.

This package does not use the zeitkort-api service, PostgreSQL, SQLite, or any other backend database. The Go web process serves the UI and stores all POC records in memory.

Important POC behavior

Companies, assignments, tasks, work sessions, and invoice-number records are held in process memory only.
Settings edited from the UI are also in-memory only.
Everything resets automatically every 10 minutes after the process starts.
A sticky, high-visibility countdown banner shows exactly when the next reset will happen.
Restarting the process also clears everything immediately.
config.json is read only at startup for the listen address and initial invoice defaults; the app never writes it.

What it does

Pick a company → assignment → task, run a live timer, and stop it manually.
Add / edit / delete companies, assignments, tasks, and work sessions.
Add manual time entries.
Generate the Faroese invoice PDF directly from the in-memory data.
Edit sender/company invoice defaults for the current 10-minute in-memory run.
Open the About menu item for a concise explanation of the POC features and implementation.

Build

Requires Go 1.26+ as declared by the original project.

go mod download
go build -o zeitkort-web .

Configure

cp config.example.json config.json
# edit config.json if needed

Only these fields are used:

listen_addr
company_*
tax_id
bank_info
payment_terms_days
mvg_percent

There are no API URL, username, or password fields in this version.

Run

./zeitkort-web -config config.json

The app logs a reset message every 10 minutes when the in-memory POC state is cleared. The browser also shows a large countdown and reloads shortly after the reset so the cleared state is visible.

As a service

sudo useradd --system --no-create-home zeitkort   # if not already present
sudo mkdir -p /opt/zeitkort-web
sudo cp zeitkort-web config.json /opt/zeitkort-web/
sudo chown -R zeitkort:zeitkort /opt/zeitkort-web
sudo cp zeitkort-web.service /etc/systemd/system/
sudo systemctl daemon-reload
sudo systemctl enable --now zeitkort-web

Notes

This is intentionally not durable. Do not use it for real time tracking.
Deletes are not cascading: remove work sessions before tasks, tasks before assignments, and assignments before companies.
The timer stops only when you click Stop, unless the 10-minute POC reset happens first.
