Demo of running BotKit for Facebook Messenger on an Express server with MongoDB storage

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

Configuration

• For local deployment

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

1. Create a Facebook page. Add Page ID in .env file (rename the .env-demo file)

2. Create a Facebook app. Add App ID in .env file

3. Add Messenger to your App, then select the Page, to generate a Page Access token. Add Token in .env file

4. install localtunnel to your computer, then use this command to make it available for webhooks

lt --subdomain yourappname --port 5000

5. Add Webhooks to your app

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

5.2) Set the app webhook url to https://yourappname.localtunnel.me/webhook

5.3) Restart your server and click verify

• For Heroku deployment

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.
