A problem with nats client

I’m new on nats, Today, I’ve installed nats client on node.js but cannot publish a message, so, I’m getting weird error. How can I fix this error?

My code:

const nc = require('nats').connect({'servers': ['nats://127.0.0.1:4222']});

nc.publish('foo', 'Hello World!');

Error:
TypeError: nc.publish is not a function

Maybe look here.

https://github.com/nats-io/nats.js/blob/main/README.md

Also my guess is you need to await the connection.

// to create a connection to a nats-server:
const nc = await connect({ servers: "demo.nats.io" });

Also - there are a couple of issues with the code above. Your code is publishing a message before the subscription is registered, so your two publishes will be received by the server before the subscription is registered, so your subscription will not get the messages.
