Have the use case to save app settings to be restore after startup/reset and decided to use .boot0.

This is the snippet I started with:

var defaults = { a:1, b:2, c:3 };
var s = require('Storage');
if (s.read('.boot0') === undefined) {
       s.write('.boot0',`var settings = ${JSON.stringify(defaults)}`);
       settings = defaults;
  }

print(settings);

// add  function to update `.boot0` if settings change ....

How do you save your app settings?

Hi! i made a simple localStorage module to save my settings, maybe can help you
This is a quick example on how to use it:

var localStorage = require("localStorage").getInstance();

var settingsObject = localStorage.getObject('settings');
if (!settingsObject) {
console.log("setting not exists");
//here's how to set
localStorage.setObject('settings', { 'ssid': 'blablabla', 'password': 'blablabla' });
}
else {
console.log(settingsObject);
//use the settings
}
