I'm trying to connect my live chat application to Heroku using the mLab extension through MongoDB. My mLab database username is: jlewallen18, for this question I have replaced my password with: MYPASSWORD.
Here are the steps I followed to set up heroku.
- git init
- git add (the package.json, index.html, server.js)
- git commit -m "Initial Commit"
- heroku login
- heroku create
- git push heroku master NOTE: this is what I see in cmd prompt when pushing to heroku:
- heroku open (This results in an application error popup on webpage)
The Heroku 'server' has the mLab extension added and a free sandbox database for testing.
What other information would you need from me to help diagnose this problem? Thanks for any and ALL help is appreciated :)
