Facebook Messenger DevKit
Setup for rapid development of bots for Facebook Messenger.
What's the trick?
Facebook Messenger works via
https, so the possibilities of local development are limited. In case you iterate fast you need to constantly redeploy your app to remote https-powered server (like Heroku, for example).
How DevKit works?
DevKit requires you to set up your app with webhook handler once. After that you have access to the stream of events via
eventsource. There're two files:
server.js is meant to be spinned on the remote https-powered server, while
index.js ought to be run locally and include your bot's logic.
What about production?
You'd better get rid of
eventsource proxy in production. It's trival task and it's up on you.
