Introduction

HNotifier is an mobile application made with the goal of enhancing communication between organizers and hackers during hackathons.

Inspiration

Since participants will be scattered in different places, getting information and the latest updates to everyone is important so the hackers would not miss anything.

This was heavily based off of the HackWestern app, which allowed the organizers to inform the hackers of delays or activity/workshop starting times.

How We Built It

The frontend was created using the Ionic framework with a Java backend. The communication between the client and server used JSON.

Challenges We Ran Into

The most annoying problem we encountered was CORS (Cross-Origin Resource Sharing). Since we had the front-end and back-end on different computers, it prevented us from effectively integrating them together. This was added onto the fact that our back-end was custom written in Java, there wasn't much documentation available.

What We Learned

We learned that API design and communication is very important. We had a bit of mishap when we misunderstood the "/hackathon/id" endpoint with "/hackathon/:id". In the future, we would strive to plan the API before hand, making less redundant code.
