Connect to node via web sockets

// Connect to node and subscribe to some events
tmJs.socket.connect({ subscribe: ['blocks', 'txs'] })
  .then(() => {

    // Alt subscribe way
    // tmJs.socket.action('subscribe', 'blocks');
    // tmJs.socket.action('subscribe', 'txs');

    // Unsubscribe out events tests
    setTimeout(() => {
      tmJs.socket.action('unsubscribe', 'blocks');
      tmJs.socket.action('unsubscribe', 'txs');
    }, 5000);
  })
  .catch(() => {});

// Subscribe to block chain events
tmJs.socket.$events.on('block', (block) => {
  console.log(block);
});

tmJs.socket.$events.on('tx', (tx) => {
  console.log(tx);
});

// Remove event listener
tmJs.socket.$events.off('tx');
