# SMS Notification Service

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

## Prerequisites

- [Deno](https://deno.land/) v2+
- A Twilio account (optional for development — falls back to console logging)

## Setup

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

## Run

```bash
# Development (auto-reload)
deno task dev

# Production
deno task start
```

## Test

```bash
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:

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

For process management, use systemd, Docker, or [Deno Deploy](https://deno.com/deploy).

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