PaperDrop: Drop Anonymous Messages Wherever You Go

Overview of My Submission

I built PaperDrop. An app that allows you to drop anonymous messages based on your location.

I got the idea about the app when I was trying to build my other side project - which lists all the crime events near to you on a map. Also, I've been planning to learn Redis for a long time. This hackathon seemed like a perfect opportunity to do it.

Technologies

Frontend: React
Backend: NodeJS(Express)
Database: MongoDB
Caching and Geo-spatial queries: Redis
Deployment: Linode

Other tools:

  • ChakraUI for styling
  • Mapbox for map
  • Certbot for SSL
  • GoDaddy for domain

Drop anonymous messages wherever you go!

PaperDrop

An app that allows you to drop anonymous messages based on your location.

Instructions:

  • Make sure your location services are turned on when using the app.
  • Users can read messages dropped by other users, given they are within the range of the message(50m).
  • Users can see messages up to 2km radius on the map.
  • A drop expires when 10 people have read it.
  • At any given point a user can only have 10 active drops. To create new drops they either delete existing drops or wait for them to expire.
  • Happy hunting! :)

How it works

Since the main focus of the app are message drops(or just drops), I'll mainly focus on that.

How the data is stored:

A drop document in MongoDB looks like this:

{
   _id: ObjectId,
   user: ObjectId,
โ€ฆ
