} from "react-realtime-crypto-prices";

const HookExample = () => {

    const tickers = useCryptoTickers(["btc", "eth"]);
    return (
        <>
            <div>Live Prices</div>
            <div>{JSON.stringify(prices)}</div>

            <div>Live Tickers</div>

        </>
    );
};

const App = () => {
    return (
        <div className="App">
            <CryptoPriceProvider cryptoCompareApiKey="<YOUR-API_KEY>">
                <HookExample />

        </div>
    );
};

export default App;

Ladies and gents we have ~live prices~

*Note: cryptoCompareApiKey is an optional prop for CryptoPriceProvider, however, if not included, the library will be unable to stream ticker data

Hooks
