yosiat opened a new pull request #85: Create reference for client
URL: https://github.com/apache/pulsar-client-node/pull/85
 
 
   Since we don’t have reference for the client, v8 can garbage collect this 
instance, which can cause the next code:
   
   ```
   const Pulsar = require('pulsar-client');
   
   (async () => {
     // Create a client
     const client = new Pulsar.Client({
       serviceUrl: 'pulsar://localhost:6650'
     });
   
     // Create a producer
     const producer = await client.createProducer({
       topic: 'persistent://public/default/my-topic',
       sendTimeoutMs: 30000,
       batchingEnabled: true,
     });
   
     let i =0;
     async function produceMessage() {
       i = i + 1;
   
       const msg = `my-message-${i}`;
       const ret = await producer.send({
         data: Buffer.from(msg),
       });
       console.log(`Sent message: ${msg}`);
       console.log(ret);
   
       setTimeout(produceMessage, 1000);
     }
   
     produceMessage();
   })();
   ```
   
   To close the connection suddenly and fail the producer.
