Request

Hemera generate and collect some request informations which are available under this.request$.

Caveats

• Request data is transfered
• Each call generate new request data

hemera.add(
  {
    topic: 'math',
    cmd: 'add'
  },
  function(req, cb) {
    cb(null, req.a + req.b)
  }
)
hemera.act(
  {
    topic: 'math',
    cmd: 'add',
    a: 1,
    b: 1,
    requestId$: '123456' // can be omitted
  },
  function(err, resp) {
    // Access to request data
    let request = this.request$
    this.act(
      {
        topic: 'math',
        cmd: 'add',
        a: 1,
        b: 5
      },
      function(err, resp) {
        // Access to request data
        let request = this.request$
      }
    )
  }
)
