# TAuth SDK Vite + React Example

This example has a Vite/React frontend and a tiny Rust backend that uses the local `tauth-sdk` crate.

It demonstrates:

- creating a TAuth login URL with `TAuthClient::auth_url`
- parsing the TAuth callback with `TAuthClient::parse_callback`
- fetching the logged-in user's TAuth profile
- storing the session/user/app data in `backend/data/db.json`
- optionally syncing app data through MTP when `TAUTH_HOST_PUBLIC_KEY` is set

## Setup

Install frontend dependencies:

```bash
pnpm install
```

Copy the environment template:

```bash
cp .env.example backend/.env
```

Set `TAUTH_PRIVATE_KEY` in `backend/.env`. Generate keys with:

```bash
pnpm --filter @tauth-example/backend exec cargo run --bin generate_keys
```

For local callback testing, `TAUTH_REDIRECT_URL` must be reachable by TAuth. Use a tunnel if needed.

## Run

Run frontend and backend together:

```bash
pnpm dev
```

Open `http://localhost:5173` and click `Login with TAuth`.

## Backend Endpoints

- `GET /api/login`: redirects to TAuth
- `GET /tauth/callback`: receives TAuth callback and stores the session
- `GET /api/me`: returns the current cookie session and cached user data
- `PUT /api/app-data`: saves JSON app data locally and optionally through MTP

The JSON database is intentionally simple for example purposes. Do not use it as-is for production.
