Satisfactory is ... all about optimized production and smooth processes.

To make the approach easier, I built this calculator as a repository database, used to power the production planner.
A mix of custom algorythms and ELK are used to provide the player with coherent production lines to be used in-game.

The calculator also bundles an interactive map which act as a full featured save editor,
by reading Unreal Engine binary save files and converting them to a JSON format.
I used Leaflet JS as a starter and build around it with some custom modules tailored to the game features.
