Processor

Handles the update data

Sends an update using the request's API URL instead of the bot's

this

// wrong
(done, { send }) => {
  send('message', { text: "doesn't work!" });
}

The reason this given example doesn't work is that send is called from out of the Processor object. Since the send method uses the Bot stored in the Processor (which is normally located at this), a ReferenceError is thrown.

The following way, send is executed from within the processor object.

// fix: call from the processor
(done, processor) => {
  processor.send('message', { text: 'works!' });
}

// fix: make use of that the processor object contains itself
(done, { data, processor }) => {
  processor.send('message', data.text)
}

As stated in Callable~callable, when a normal function is used as the callable instead of an arrow function, this is bound to the Processor object, so that can also be used.

// fix: call send from `this` in a normal function
function someCallable(done, { data }) {
  console.log('can still use the destructed processor to have easier' +
   'access to properties like', data);
  this.send('sendMessage', { text: 'works!' })
}
