To interact with Pulsar, you first need a client object. You can create a client instance using a new operator and the Client method, passing in a client options object.

Here is an example:

const Pulsar = require('pulsar-client');

(async () => {
  const client = new Pulsar.Client({
    serviceUrl: 'pulsar://localhost:6650',
  });

  await client.close();
})();

For a complete list of client configurations, see here.
