mailer.js

This file is the express.js route to handle the 'Contact Me' forum submission. Not sure if the client side code matters but I just send off an axios post call to the express route above, then return success (pop up confirmation) or the error message and display that.

Everything works in development but when I try it on digitalocean I get the error in errorMessage. Could there be something I have done incorrectly with regards to server setup. The tutorials I have used to help me are as follows: https://www.digitalocean.com/community/tutorials/how-to-set-up-a-node-js-application-for-production-on-ubuntu-14-04 https://code.lengstorf.com/deploy-nodejs-ssl-digitalocean/#install-nginx

Structuring a Mongo Database Documents

Whether or not one should embed nested docs or to use the reference by ID and populate later is a great question and has been answered nicely on StackOverflow
