This is a boilerplate that I've made for Dialogflow API v2.

Instalation

Its easy to use and setup. You can clone/fork the repository and run

npm install

Developer mode

To start the application in dev mode, run:

npm run dev

Adding a new action

To add a new action, you need to edit the App/Controllers/Dialogflow/index.js The method actionList() returns a object literal. You can add your custom action inside this object. You can follow the examples already added inside this file. It has supports for Messenger custom payload.

Enabling and configuring the webhook fulfillment

To enable the webhook trigger:

• Open Dialogflow website.
• Select your agent.
• Click in "Fulfillment" menu tab.
• In URL field, you need to specify where is hosted your project. For localhost purposes, you can use ngrok
• If you're using ngrok, just run ngrok http 3000 and copy the https url.
• The boilerplate will create a /actions/ endpoint of POST type.
• Copy the ngrok https url and add the /actions/ endpoint, it will look like:

https://customNgrokUrl/actions/

• Save it and go to your Intents.
• Select a whatever intent.
• In the end of the page, in the Fulfillment label, select the Use webhook option.
• Save it and test.

Facebook support

This webservice, has support for facebook card types. You can use custom cards and payloads by reading the Facebook developers page.

To enable the Messenger support, you need to enable the integration and the support in your intent.

Async support

It has async support, you need to do by your own.
