API documentation

Examples

// Full example with the remotebot example (from the official Rasa core repo)

const SENDER_ID = 'anon'
// Greet the bot
const msg1 = 'hello'
rc.parse(msg1, SENDER_ID).then(reply => {
  return rc.continue({
    executed_action: 'greet'
  }, SENDER_ID)
}).then(cont1 => {
  // next_action is action_listen in this case
  // therefore we can initiate a new parse request

  // Send venues request
  const msg2 = 'Whats the next event'
  return rc.parse(msg2, SENDER_ID)
}).then(reply => {
  return rc.continue({
    executed_action: 'search_concerts',
    events: [{ event: 'slot', name: 'venues', value: [
      {name: "Big Arena", reviews: 4.5},
      {name: "Small Arena", reviews: 4.2}
    ]}]
  }, SENDER_ID)
}).then(cont2 => {
  // you get the point...
})
