This is a simple Sinatra app that's deployable to Heroku and can act as a logging bridge for Papertrail.
It uses sinatra-cross_origin to support CORS.
Name of app in heroku => papertrail-js-logs https://dashboard.heroku.com/apps/papertrail-js-logs
The current PAPERTRAIL_API_TOKEN is set to Ruben's api token.
To connect the heroku app to our standalone papertrail account we needed to run heroku drains:add syslog+tls://logs7.papertrailapp.com:40793. More details on this here
