We developed a chat application in Vue where you can set the delay before a message is received and that also includes lots of other features.
We chose the challenge because it's a interesting problem and writing chat applications is fun.
It was made with Node.js, Vue, Bootstrap, Firebase realtime database, and Javascript. We wrote code in Visual Studio Code, used Github Desktop for version control, communicated via Discord, and made the presentation in Google Slides.
None of us knew web development besides static websites at the start of the hackathon, so we had to learn quickly. That meant learning Node.js, Vue, Bootstrap, more Javascript, and Firebase in 2 days.
We used space agency data for information about the light delay to Mars as well as Mars imagery from NASA and ESA to create a 3D model of Mars that was used for backdrops on the slideshow and the website.
