Sugarcube 2 (Twine) Ajax Saving
This module implements auto saving/loading via ajax. It does not deal with the server side or authentication, it's up to you to implement that.
Behavior
When your story loads, this module will make a simple GET request to the url stateUrlPath (parameter). If the repsonse is a text/plain save data, it will be passed to Sugarcube's Save.unserialize() to load the data. If this fails, nothing unordinary happens. The base saving system will take effect.
On the saving side, anytime a passage is loaded (ie whenever the normal autosave runs), this module will make a PUT request with the save state data to stateUrlPath.
Installing and Loading
If using npm with Tweego/Twee, you can simply install with npm i -S sugarcube-ajax-save.
For Twine Desktop/Web... I'm not sure yet best approach for installing.
After installed, it needs to be loaded somewhere in your global js:
import ajaxSaving from 'sugarcube-ajax-save';
ajaxSaving({ Config, State, $document: $(document), jQuery, LoadScreen, LZString, stateUrlPath });
Further Improvements
Loading There may be a better standard for Twine/SugarCube modules.
