MMM-JAST stopped updating a couple of days ago.

[wyovino]

@KristjanESPERANTO I’m running an old version of MM and this update just killed it completely. The reason I stayed with Version 1 was because I’m using a Pi Zero2W and the MMM-Jast ticker was painfully slow when scrolling. I guess I have no choice now.

[wyovino]

@KristjanESPERANTO I updated to the latest MM and the horizontal scroll works but it stutters badly on a Zero2W. I’ve tried changing the settings but none of them give an acceptable appearance. I have a request for an enhancement of the Vertical scrolling feature.

The ticker scrolls up until it gets to the last instrument, then scrolls in the opposite direction. This is fairly ugly. Can it be made to continually scroll in one direction?

@wyovino

the horizontal scroll works but it stutters badly on a Zero2W.

There are some performance hints in the README: https://github.com/jalibu/MMM-Jast#performance-on-raspberry-pi. Feedback would be nice if these are helpfull.

The ticker scrolls up until it gets to the last instrument, then scrolls in the opposite direction. This is fairly ugly. Can it be made to continually scroll in one direction?

Oh I didn’t noticed that before. I doubt that this was intentional, so I just changed it. Please update to the new release v2.10.1 🙂

[wyovino]

@KristjanESPERANTO Perfect! Thanks. I had tried the performance hints but they didn’t really help. This is a good alternative.

[KristjanESPERANTO]

@wyovino Okay, I’m glad we were able to improve the situation 🙂 Can this thread marked as solved?

[wyovino]

@KristjanESPERANTO Yes, thanks again.

@KristjanESPERANTO hi, i have updated to the latest version but my modules is still stuck at loading. any idea?

[KristjanESPERANTO]

@1a2a3a Any unusual log entries in the node or browser console? Do you use the current MM version?

@KristjanESPERANTO
I hate to jump on the bandwagon, but I am also having an issue with it saying undefined. I did do the git pull and npm install on MMM-Jast since it is the only one of 48 modules that stopped working… Kind of amazing, Since some of them are getting to be old modules… Running Trixie and latest MM. Pi4 8gb fully up to date…

[KristjanESPERANTO]

@plainbroke Please update to v2.10.3 and check. If it doesn’t work: Any unusual log entries in the node or browser console? Show me your config.

[plainbroke]

@KristjanESPERANTO
I had to remove and reinstall, just updating with git pull did not fix it, but the reinstall fixed it. Thanks for your efforts.
Much appreciated.

[sdetweil]

@plainbroke did you do an npm install after the git pull?

[plainbroke]

@sdetweil
Yes
npm ci
Like his read me says to.
Worked with reinstall so alls good on my mirror again.

[1a2a3a]

Ok, after git pull, had to do a npm ci and that fixes it!

Hi, I’m stuck at “Loading…” on this module as well. This is a new build I’ve been working on in the last week or so, first timer with MagicMirror so hopefully I’m not missing something obvious. I’ve not been able to get MMM-Jast to display any values at all, but I can get other modules working no problem.

I’m running the latest 2.10.3 version and I’ve removed and reinstalled it a few times, as well as completely reloaded my raspi device from scratch, but no luck. pm2 logs don’t show any errors, but I’m unsure what other logs to evaluate.

Here is my config. I’ve tried a bunch of different config options to see if anything kicks it into gear, including a completely bare config with just the example config from the README, but each attempt just shows “Loading”.

    {
      module: "MMM-Jast",
      position: "middle_center",
      config: {
        displayMode: "none",
        stocks: [
          { name: 'DJIA', symbol: 'DIA' },
          { name: 'SP500', symbol: 'VOO' },
        ]
        },
    },

[KristjanESPERANTO]

@vgardenn Interesting. Your config works on my system.

Please show us your system information (you can see it when you run npm run start) - and looks like this:

@KristjanESPERANTO Here is my system info from the npm run start output:

This also highlighted an error I may have been missing in the pm2 logs output, so it may not be a module issue at all. I apologize if I had you looking at this and it was just an issue with my MM setup. I’ll start researching what this error means:

[2026-01-19 18:14:54.626] [ERROR] [app] WARNING! Config file appears empty, maybe missing module.exports last line? 
[2026-01-19 18:14:54.627] [ERROR] [app] WARNING! Could not load config file. Starting with default configuration. Error found: TypeError: userConfig.modules is not iterable

@vgardenn show the last 5 lines of config.js
Compare to the sample in the same folder

What is this?

userConfig.modules

[vgardenn]

I’m unsure what that userConfig.modules is, from my googling it seems maybe related to node.js?

Here is the entire config.js. The last 5 lines look similar to the sample config:

let config = {
  modules: [
    {
      module: "MMM-MagicMover",
    },
    {
      module: "clock",
      position: "top_bar",
      config: {
	timeFormat: 12,
	displaySeconds: false,
	dateFormat: "dddd, MMMM D",
        }
    },
    {
      module: "weather",
      position: "top_center",
      config: {
	weatherProvider: "weathergov",
        type: "current",
	tempUnits: "imperial",
	roundTemp: true,
	showFeelsLike: false,
	colored: true,
	showSun: false,
	lat: "xxxxxx",
	lon: "xxxxxxx",
        }
    },
    {
      module: "MMM-Jast",
      position: "middle_center",
      config: {
	displayMode: "none",
	stocks: [
	  { name: 'DJIA', symbol: 'DIA' },
	  { name: 'SP500', symbol: 'VOO' }
	]
        }
    },
    {
       disabled: true,	
       module: "MMM-NowPlayingOnSpotify",
       position: "bottom_center",
       config: {
       	 showCoverArt: false,
         clientID: "<YOUR_CLIENT_ID>",
         clientSecret: "<YOUR_CLIENT_SECRET>",

    	 }
    },
  ]
};

@vgardenn these lines are not at the bottom of your config file

/*************** DO NOT EDIT THE LINE BELOW ***************/
if (typeof module !== "undefined") { module.exports = config; }
