How we built a back end system for Uber-like maps with animated cars
This is an interesting challenge, I'm building something similar for public transport, and the latency in updates tends to make things bad.On browsers I'm using turf.js to calculate movements and then animate them. I calculate where the bus/train is likely to be in the next 30 seconds, and then send that data through to the user. Then I keep updating the vehicle marker frequently until that 30 seconds time out, or until another update comes in.I'm struggling to do the same on Android because I haven't found a good turf.js equivalent there.
