Shared Preferences for Fitbit

Android-like, memory cached and persistent key-value local storage for Fitbit Ionic SDK.

Usage

It's a super simple script, so I'll be brief there.

Put the shared_preferences.js script in the common folder, or wherever you want.

Import the script:

import * as prefs from "../common/shared_preferences";

Store your values:

prefs.setItem("keep_screen_on", true);
prefs.setItem("user_name", "John Doe");
prefs.setItem("birth_year", 1988);

Read your values:

let keepScreenOn = prefs.getItem("keep_screen_on");
let userName = prefs.getItem("user_name");
let birthYear = prefs.getItem("birth_year");

The script loads the data automatically on start, and saves it on close. You can, however, load or save (synchronously) on demand:

prefs.save();
prefs.load();

You can also enable debug logs or change storage file right within the script:

const DEBUG_MODE = true;
const FILE_NAME = "different_file.json";

And that's all there is :-)).
