Attractor
Attractor is a new geo-marketing app.
Advertisers can employ virtual Attractors to make announcements in the streets of their cities and advertise local businesses and events.
Subscribers will hear announcements from nearby Attractors only, so you’ll always know when a new coffee shop opens close to you!
Setup
You'll need a recent LTS version of Node.js and Git.
Clone this repository to your computer and run:
npm install # to install the dependencies of this project
npm test # to run the tests
npm test -- --watch # to keep running the tests in the background
Exercise
- Subscriber should receive announcements only when they're within range of an attractor
- Subscriber should receive each announcement exactly once while she's within range
- Announcements have a configurable max TTL
