I added the core trading mechanics to the SpaceTraders client today. Ships can now purchase and sell cargo at different locations, which is the fundamental gameplay loop of the game.

I also implemented flight plans so ships can actually travel between locations. This involved extending the API client with the relevant endpoints and adding a new ship slice to Redux to manage ship-specific state separately from the main game state.

The location model got expanded to include more detail about what’s available at each waypoint, which will be useful for making informed trading decisions.
