  • yarn yarn add react-use-ark


Simply import ARK hooks that you wish to fetch data in your React application.
Each hook:

  • starts with a resource name as 'useTransactions...', 'useBlocks...', 'useDelegates...', 'useWallets...'.
  • always returns the same state object { response, isLoading, error } where response type is defined to easily access it's properties.
  • accepts fetchOnMount boolean argument, which can be used as an utility to cover common pattern of data fetching when component mounts.
  • accepts network argument which is an enumeration object 'DEVNET | MAINNET | TESTNET' or user defined string (localhost). Set it appropriately to your needs, depending on running relay.
import React from 'react';
import { useTransactionsLatest } from 'react-use-ark';

const App = () => {
  // Get 20 latest transactions when App component mounts.
  const [{ response, isLoading, error }] = useTransactionsLatest(1, 20, true);
  return (
      {isLoading && <div>Loading...</div>}
      {error && <div>Error fetching data: {error}</div>}
      {response && (
          { => (
            <li key={}>
              <div>Amount: {transaction.amount}</div>
              <div>Fee: {transaction.fee}</div>
              <div>Sender: {transaction.sender}</div>
              <div>Recipient: {transaction.recipient}</div>
              <div>Block ID: {transaction.blockId}</div>
              <div>Confirmations: {transaction.confirmations}</div>

ReactDOM.render(<App />, document.getElementById('root'));
