I wish this existed so I could use it in my Electron app

auto-persister.js

import Path from 'path';
import AppPaths from 'app-paths';
import Persist from 'auto-persister';


let settings = Persist.manageFile({
	path: Path.join(ApPaths.ConfigFile, 'default.myapp-settings'),
	json: true, // read & write will marshall JSON automatically
	autocreate: true, // file (and parent dirs) will be immediately created if they don't already exist
	initialData: DefaultSettings, // value that will be returned if file doesn't exist, and that will be written if autocreate true
	// all other options are passed to underlying FS methods
	encoding: 'utf8',
	...
});


// invoke whenever to write data into the file
settings.write({ data: someObj, async: true })


// invoke whenever to read data from file
settings.read({ async: true })
