We have many friends living in cities around the world but we rarely visit them since the flights are usually too expensive. So we build an app which gives you alerts once the flights to your friends drop to a low price.
What it does
We get your friendslist from facebook and then give you the option to choose the ones you want to track the flights for. We then send you a weekly email, with the 3 best picks, where the price is much lower then usually for a weekend trip.
How I built it
We use node.js with firebase to do the backend work. The flight prices are querried with the Amadeus API and we then send the weekly mail with node.js
Challenges I ran into
Time, time, time....
