stan.js doesn't try to reconnect

I have the following code, running on node-nats-streaming@0.3.2, which successfully connects to server setup using docker using nats-streaming:0.18-alpine image:

const STAN = require('node-nats-streaming')

const { NATS_CONN_URL } = require('../config')

let url = NATS_CONN_URL
let sc = STAN.connect('mail-cluster', 'node-worker', {
  url,
})

// emitted whenever there's an error. if you don't implement at least
// the error handler, your program will crash if an error is emitted.
sc.on('error', (err) => {
  console.log("[NATS] Error:", err)
})

// connect callback provides a reference to the connection as an argument
sc.on('connect', () => {
  console.log(`[NATS] connected`)
})
 
// emitted whenever the client disconnects from a server
sc.on('disconnect', () => {
  console.log('[NATS] disconnect')
})
 
// emitted whenever the client is attempting to reconnect
sc.on('reconnecting', () => {
  console.log('reconnecting')
})
 
// emitted whenever the client reconnects
// reconnect callback provides a reference to the connection as an argument
sc.on('reconnect', () => {
  console.log(`[NATS] reconnect`)
})
 
// emitted when the connection is closed - once a connection is closed
// the client has to create a new connection.
sc.on('close', function () {
  console.log('[NATS] close')
})
 
// emitted whenever the server returns a permission error for
// a publish/subscription for the current user. This sort of error
// means that the client cannot subscribe and/or publish/request
// on the specific subject
sc.on('permission_error', function (err) {
  console.error('[NATS] got a permissions error', err.message)
})

However, when there are network connectivity issues, there are no reconnect attempts, it just fails with the following output:

[NATS] connected
[NATS] close

Am I doing anything wrong?

Great…Let me give a try…

Also - if you are starting work using stan.js, you should really stop and start looking at jetstream instead, which is supported directly by all our current javascript clients. https://github.com/nats-io/nats.deno/blob/main/jetstream.md
