Migrating Settings from 4.x to 5.0

[selfboy3]

Hey all,

I am trying to migrate my app from Fitbit SDK 4.0 to 5.0 and before used the "simple-settings" infrastructure. This utilized messaging and callback when setting and updating settings. It worked great, but now my "data" variable is returning null. I have included my code from the companion-settings and device-settings.

FROM COMPANION SETTINGS

import * as messaging from "messaging";
import { settingsStorage } from "settings";

export function initialize() {
  settingsStorage.addEventListener("change", evt => {
    if (evt.oldValue !== evt.newValue) {
      sendValue(evt.key, evt.newValue);
    }
  });
}

function sendValue(key, val) {
  if (val) {
    sendSettingData({
      key: key,
      value: JSON.parse(val)
    });
  }
}

function sendSettingData(data) {
  if (messaging.peerSocket.readyState === messaging.peerSocket.OPEN) {
    messaging.peerSocket.send(data);
  } else {
    console.log("No peerSocket connection");
  }
}

FROM DEVICE_SETTINGS

/*
  Responsible for loading, applying and saving settings.
  Requires companion/simple/companion-settings.js
  Callback should be used to update your UI.
*/
import { me } from "appbit";
import { me as device } from "device";
import * as fs from "fs";
import * as messaging from "messaging";

const SETTINGS_TYPE = "cbor";
const SETTINGS_FILE = "settings.cbor";

let settings, onsettingschange;

export function initialize(callback) {
  settings = loadSettings();
  onsettingschange = callback;
  onsettingschange(settings);
}

// Received message containing settings data
messaging.peerSocket.addEventListener("message", function(evt) {
  settings[evt.data.key] = evt.data.value;
  onsettingschange(settings);
})

// Register for the unload event
me.addEventListener("unload", saveSettings);

// Load settings from filesystem
function loadSettings() {
  try {
    return fs.readFileSync(SETTINGS_FILE, SETTINGS_TYPE);
  } catch (ex) {
    return {};
  }
}

// Save settings to the filesystem
function saveSettings() {
  fs.writeFileSync(SETTINGS_FILE, settings, SETTINGS_TYPE);
}

FROM INDEX.JS IN THE APP DIRECTORY

function settingsCallback(data) {
  console.log(data);
  if (!data) {
    return;
  }
  if (data.colorB) {
    body.style.fill = data.colorB;
  }
  if (data.colorH) {
    mixedtext.style.fill = data.colorH;
  }
  if (data.selection) {
    versionNum = data.selection.selected;
  }
}
settings.initialize(settingsCallback);

FROM INDEX.JS IN THE COMPANION DIRECTORY

import * as settings from "./companion-settings";

settings.initialize();

Thanks for any help anyone can provide. If this is not a good way to do settings, please lead me on the right path. Thanks again.
