How can i initialize server as client just one time in react native?

render(){    const { wifi } = this.state;    /*const client = TcpSocket.createConnection({        port: 80,        host: '192.168.4.100',        tls: false,        interface: 'wifi',        //localAddress: '192.168.4.101',    }, () => {        client.write('APPSETTING CONNECTED');    });*/

I put this code in render, so it results to multi connection by same IP.How can i initialize this server as client just one time in react native?
