An SMS notification service for Time Safari that handles phone number verification and scheduled SMS notifications (daily reminders, activity digests). It authenticates users by forwarding JWTs to an endorser-ch server, stores verified phone numbers and notification preferences in SQLite, and sends messages via Twilio.

Prerequisites

Deno v2+
A Twilio account (optional for development — falls back to console logging)

Setup

cp .env.example .env
# Edit .env with your configuration

Run

# Development (auto-reload)
deno task dev

# Production
deno task start

Test

deno task check   # Type-check
deno task test    # Run tests

Deploy

The service is a single Deno process with a SQLite database file. To deploy:

Copy the project to your server
Set environment variables (see .env.example)
Run deno task start

For process management, use systemd, Docker, or Deno Deploy.

The SQLite database is created automatically on first run and migrations are applied on startup.
