dump / restore game state to / from json.
See original GitHub issueThis is a feature request
It would be nice to see a simple api to dump game state to json and restore it. Something like
let json = game.dump()
game.restore(json)
This could be used to save games in a database or create save/restore points.

@Piterden - thank you for sharing! It looks like you’re saving each move into a table and then restoring the board by re-applying each move individually. This is effectively what I did in the stdlib implementation.
An alternative, I recently noticed, which I forgot about in my original reply on this issue thread, that there is a way to load a game from a move history: https://github.com/brozeph/node-chess/blob/master/src/game.js#L86. One possibility might be to serialize the move history as JSON (
JSON.stringify(gameClient.game.moveHistory)
) and then use that when creating a game subsequently for reload… if this sounds interesting or worthwhile, I could implement aload
method from the game clients that does just this (as an alternative to thecreate
method).Should we keep this issue open, or does the FEN load address this need?
