#### Simple code showcase

```js
import { Huobi, Binance } from 'zenfuse';

const huobi = new Huobi.spot();

// Fetch current BTC/USD price from Huobi exchange
huobi.fetchPrice('BTC/USD').then((price) => {
    console.log('Current BTC/USD price:', price);
});

// Fetch all current listing coins from Huobi
huobi.fetchTickers().then((tickers) => {
    console.log('All Huobi tickers', tickers.join(', '));
});

const binance = new Binance.spot();

// Authenticate instance, so you can use private methods
binance.auth({
    publicKey: '***',
    privateKey: '***',
});

// Create connection instance for account events
const accountDataStream = binance.getAccountDataStream();

// Open websocket connection
await accountDataStream.open();

// Subscribe for order updates on account
accountDataStream.on('orderUpdate', (order) => {
    console.log('Order Update:', order);
});

// Sell 0.0004 ETH for 100 USDT, and we receive order update event above
binance.postOrder({
    symbol: 'ETH/USDT',
    type: 'limit',
    side: 'sell',
    price: 100,
    quantity: 0.0004,
});

// Create connection instance for market data
const marketDataStream = binance.getMarketDataStream();

// Open websocket connection
await marketDataStream.open();

// Subscribe for current BTC price
marketDataStream.subscribeTo({
    channel: 'price',
    symbol: 'BTC/USDT',
});

// After we will handle newPrice events
marketDataStream.on('newPrice', (event) => {
    console.log(`Current ${event.symbol} price`, '->', event.price);
});
```
