How to use the @logux/core.MemoryStore function in @logux/core

async function tick () {
  if (stop) return

  let nodeId = `1:${ ++index }`
  let connection = new WsConnection('ws://localhost:31337', WebSocket)
  let log = new Log({ nodeId, store: new MemoryStore() })
  let node = new ClientNode(nodeId, log, connection, {
    credentials: 'secret',
    subprotocol: '1.0.0',
    outMap: map
  })

  node.on('clientError', e => {
    stop = true
    throw e
  })
  node.catch(e => {
    stop = true
    throw e
  })

  node.connection.connect()

}
