Looking for games built with Phaser that have internal map editors

[Babsobar]

Hello everyone,

A friend and I are working on a multiplayer game built with Phaser. Our first project!

We  are making a turn-based strategy game in which we would like to include an in-game map editor and builder.
I'm looking for examples of code or games that can inform us on how to save, store and re-use the maps created by the user.

I've been having trouble with understanding how to extract the data input by the user in a compact, no server load, way.

Thanks,
Bab
