Botkit demo for Messenger, using Express and Mongo

This app is a demo of using Botkit to create a Facebook Messenger bot, using the MongoDB adapter for storage and Express to serve webpages.

The same demo for Slack bots can be found here

Features

Serves webpages through standard express routes app/routes/routes.js
Uses Monkii as MongoDB driver
Stores users ID when a new user clicks on "Send to Messenger"
Offers a welcome message when user clicks on "Send to Messenger", replies to Hello, and generally just repeats what you just said

There are quite a number of steps to set up a Facebook bot

Create a Facebook page. Add Page ID in .env file (rename the .env-demo file)
Create a Facebook app. Add App ID in .env file
Add Messenger to your App, then select the Page, to generate a Page Access token. Add Token in .env file
install localtunnel to your computer, then use this command to make it available for webhooks

lt --subdomain yourappname --port 5000

5.1) Choose a verify token, add it to the .env file as well

5.3) Restart your server and click verify

Add Page ID, App ID, and token as environement variables. Change the webhook route to match your deployed domain name.

You can use MongoLab add-on to add Mongo storage, they have a free tier.

Contributions are more than welcome! In terms of style, I use standard style with camelcase and brace-style disabled.
