EDIT: unmaintained, you can use something like https://github.com/chen-ye/hubot-fb which uses the new Messenger API 👻
A hubot adapter for Facebook messenger!
Set envvars HUBOT_FB_USERNAME and HUBOT_FB_PASSWORD to use this with a Facebook account.
Install hubot. Make sure to npm install --save hubot-messenger to add this module.
Run the command HUBOT_FB_USERNAME=<email> HUBOT_FB_PASSWORD=<pass> ./bin/hubot -a messenger to run the bot from your local computer.
If you want to run hubot with a local version of hubot-messenger, use npm link.
