FamilySync

A self-hosted family organization hub for a two-person household. One color-coded calendar view across all family members' Fastmail calendars, plus shared collaborative lists (groceries, gift ideas) — delivered as a React PWA with no app store required.

What It Does

• Unified calendar — aggregates each member's Fastmail CalDAV calendars into a single color-coded view via tsdav + ical.js
• Shared lists — collaborative grocery and gift-idea lists with live sync via Server-Sent Events
• PWA — installable on iOS (Home Screen) and Android; push notifications via VAPID
• Single sign-on — all auth flows through your existing Authelia OIDC deployment

Prerequisites

• Node.js 22 LTS
• pnpm 11.5.1 (corepack enable pnpm)
• Docker + Docker Compose (for MariaDB, Redis, and production deployment)

Installation

git clone <repo-url> familysync
cd familysync
pnpm install

Copy the environment template and fill in values:

cp .env.example .env   # then fill in values — see Environment Variables below

Required environment variables (set in .env or your Docker host):

Variable	Description
DB_PASSWORD	MariaDB password for the familysync user
DB_ROOT_PASSWORD	MariaDB root password
OIDC_ISSUER	Authelia OIDC issuer URL
OIDC_CLIENT_ID	OIDC client ID (default: familysync)
OIDC_CLIENT_SECRET	OIDC client secret
OIDC_REDIRECT_URI	Callback URL registered in Authelia
OIDC_AUTH_SECRET	Random secret for session cookie signing
APP_PASSWORD_ENCRYPTION_KEY	Key used to encrypt stored Fastmail app passwords
VAPID_PUBLIC_KEY	VAPID public key (npx web-push generate-vapid-keys --json)
VAPID_PRIVATE_KEY	VAPID private key (never commit)
VAPID_SUBJECT	VAPID subject (mailto:you@example.com)

Quick Start

Development (with hot-reload API and Vite HMR):

# Start backing services
docker compose -f docker-compose.yml -f docker-compose.dev.yml up mariadb redis

# Run migrations
pnpm --filter @familysync/api db:migrate

# Start API (in one terminal)
pnpm dev:api

# Start PWA (in another terminal)
pnpm dev:pwa

Production (Docker Compose):

docker compose up --build

The API listens on port 3000. The PWA build is served separately (Vite preview or a static host in front of the API container).

Monorepo Structure

apps/
  api/        Hono backend — CalDAV sync, OIDC auth, lists API, push notifications
  pwa/        React 19 PWA — calendar view, lists UI, service worker
docker-compose.yml       Production services (API, MariaDB 11, Redis 7)
docker-compose.dev.yml   Dev overrides (bind-mount src/, expose DB/Redis ports)

Commands

Command	What it does
pnpm dev:api	Start API in watch mode (dist/ must be built first)
pnpm dev:pwa	Start Vite dev server with HMR
pnpm build	Build both api and pwa
pnpm test	Run API test suite (vitest)
pnpm lint	Lint all workspaces
pnpm typecheck	Type-check all workspaces
pnpm --filter @familysync/api db:generate	Generate Drizzle migration from schema changes
pnpm --filter @familysync/api db:migrate	Apply pending migrations to MariaDB

Tech Stack

Layer	Technology
Backend runtime	Node.js 22 + TypeScript, Hono 4.12.23
Database ORM	Drizzle ORM 0.45.2 on MariaDB 11 (via mysql2)
Auth	@hono/oidc-auth 1.8.3 — authorization code + PKCE against Authelia
Calendar	tsdav 2.2.2 (CalDAV) + ical.js 2.2.1 against Fastmail
Push	web-push 3.6.7 (VAPID)
Live sync	Server-Sent Events + Redis 7 pub/sub
Frontend	React 19, Vite 8, vite-plugin-pwa 1.3, TanStack Query 5, Zustand 5
Calendar UI	Schedule-X 4.6

Calendar Integration

FamilySync reads and writes calendars via CalDAV against Fastmail — not JMAP (not available for Fastmail calendars). Configure your Fastmail app password under the "Mail, Contacts & Calendars" scope. The principal URL follows the pattern:

https://caldav.fastmail.com/dav/principals/user/<your-fastmail-address>/

Store the app password in the database via the /me endpoint after first login.

Deployment

See docs/deployment.md for Unraid/Docker Compose deployment notes including the Pangolin/Newt tunnel configuration.
