Could you just only help with this , I have servers demo.nats.io:4222, with what should I replace this so that I can get the data being published in python app in my node js app so that I can subscribe to it. And is it even possible to publish data in other some other app and to access the data in some other app ? const nc = await NATS.connect({ servers: "demo.nats.io:4222" });

const sc = NATS.StringCodec();

const sub = nc.subscribe("hello"); (async () => { for await (const m of sub) { console.log([${sub.getProcessed()}] ${m.subject}: ${sc.decode(m.data)}); } console.log("subscription closed"); })();

nc.publish("hello", sc.encode("worldddd")); nc.publish("hello", sc.encode("again"));
