The timestamp microservice project is a Node/Express
app that takes either a human-readable date or a unix datetime and converts it to the other. This was my first
project using Node and Express, so there was a lot to learn for this fairly simple application. This was also the first
time I had used Heroku to host an application so there was some setup required so that I could easily push my changes
to the Heroku server using
git push heroku master.
To get my feet wet with Node and Express, I took the Server-side Development with NodeJS course on Coursera and strongly recommend it. It covers Node, Express, MongoDB, and Mongoose, so you can use it to learn everything you might need for the M, E, and N parts of the MEAN stack.
