## Installation

- Install source:

```sh
npm i uyem
```

## Settings

- To be able to create connections on a host other than localhost, you need to connect SSL certificates.

Sample setup SSL certificates from Let's Encrypt for client and for server together with `nginx` see [docs/SSL.md](./docs.SSL.md)

---

- To remote access between units using valid `iceServers` on client is required:

---

```javascript
const iceServers = [
  {
    urls: ['stun:127.0.0.1:3478'],
  },
  {
    urls: ['turn:127.0.0.2:3478'],
    username: 'username',
    credential: 'password',
  },
];
```

See [docs/COTURN.md](docs/COTURN.md) for more details.

## Server preparation

- Add property `migrate` to the `scripts` block of `package.json`:

```json
"migrate": "uyem --db mysql://root:root@127.0.0.1:3306/uyem_db --migrate"
```

- Conducting migrations:

```sh
npm run migrate
```

## Usage on client

- Import module styles:

```javascript
import 'uyem/packages/client/dist/styles.css';
```

- Import component:

```javascript
import Uyem from 'uyem';
```

## Usage on sever

```javascript
const { createServer } = require('uyem/server');

createServer({ port: 3233, db: 'mysql://root:root@127.0.0.1:3306/uyem_db' });
```
