# Build a Full To-Do List with GenosDB

A complete, reactive to-do list with filtering, persistent OPFS storage, and real-time P2P sync — built with [GenosDB](https://genosdb.com/building-genosdb-p2p-database) and vanilla JavaScript, no backend. For a simpler version, see the [quick To-Do List](https://genosdb.com/genosdb-todolist).

## Key Features

- **Add, complete, and delete tasks** with instant P2P sync
- **Reactive UI** — `db.map()` streams changes in real-time
- **OPFS persistence** — data survives page reloads
- **Fully serverless** — no backend required
