Our task is to create a trip cost calculator app.
Imagine going on a trip, and you have your app (which can be a progressive web app, or a mobile app for example) where you add any expense you make. Gasoline, hotels, food, tickets and so on.
When the trip ends, you archive it and it becomes part of the history - which you can navigate and see how much you spent in the past trips.
We’re not going to create the frontend of the application here, as this course is focused on Node.js and I don’t want to dilute the concepts.
What we’re going to build is the API for this project, using Express and MongoDB.
