Timeout

NATS is fire and forget, reason for which a client times out could be many things:

• No one was connected at the time (service unavailable)
• Service is actually still processing the request (service takes too long)
• Service was processing the request but crashed (service error)

hemera.act(
  {
    topic: 'math',
    cmd: 'add',
    a: 1,
    b: 1
  },
  function(err, resp) {
    // err instanceOf TimeoutError
  }
)

Change global timeout

const hemera = new Hemera(nats, { timeout: 3000 })

Change timeout per call

hemera.act(
  {
    topic: 'math',
    cmd: 'add',
    a: 1,
    b: 1,
    timeout$: 5000
  },
  function(err, resp) {}
)
