I’ve watched as users continue to struggle with formatting in config.js and i think I have a solution

https://github.com/sdetweil/MMM-Config

it automatically discovers what you have installed (in the modules folder) and what you are using (in config.js)

and will let you turn them on/off, edit the settings and change the module positions. all in a form.

every time u start MagicMirror it will check to see if config.js has changed since last time, and if you’ve added or removed something from the modules folder… it will construct a form that will allow you to edit the settings of everything.

and then save it back to config.js (after saving the current copy) (and if using PM2) restart MM to use that new config.js

also works on Windows installations of MM.

it can put a QR code on the screen so you can use your phone or ipad, or other scanning device so u don’t have to know the url
and can also be bookmarked etc…
I supply a css to allow you to change color of the form.

some screen shots
initial form screen

base expanded

some places I can tell what you can do

modules list, blue is enabled, red disabled… (u can changed that in the css file)

sample module form section , discovered from module source file and config.js usage (if any)

module position info, cause you may need one above another, (clock and calendar for example)
and things in other areas…

if u disable a module (checkbox), the contents STAYS in config.js, otherwise it would lose the important info (apikeys, urls, etc)

thanks to a few testers(who can name themselves if they want) , we’ve gone thru a lot of modules, but not all…
so I expect there will be reports of troubles… give it a shot and let me know…

it currently doesn’t support multiple instances of the same module (used for pages and carousel or similar type modules ), or things like my Covid19 charter.
but I have an open issue and am working on it…

given that we will have a regular update quarterly, and we have such a large number of new users experiencing troubles after updates (mostly cause they have a ton to learn)… I have developed a script I would like to get included for future updates…

it should handle all the work…
and give you a trial run of all that…

only applying changes if u request them

give it a try
this works on Mac as well

  bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)"

no changes are made to the local repo or the working copy

if you WANT to actually apply the changes do

  bash -c  "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/upgrade-script.sh)" apply

there is a log file in the installers folder…

just a note for spammers,

there is no tolerance.

if it does not apply to MagicMirror, then your posts will be removed, and you will be banned.

Period, no second chances.

the message module not found has nothing to do with MagicMirror ‘modules’ but a library USED by a MagicMirror module. sadly we cannot change or intercept the message

a typical error

Cannot find module ‘request’

In recent mm releases we have removed libraries that are discontinued ( aka deprecated).

many mm modules used these but didn’t document it. so they fail

to fix this you need to install the library in the module folder,
so do

cd ~/MagicMirror/modules

cd modulename (where modulename is the module having the error)

once there, do

ls package.json

if the module does NOT provide that file ( ls reponse is ‘No such file or directory’) then do

npm init -y

NEVER EVER do this in the MagicMirror folder
if you do/did, then do
git checkout package.json

then regardless (in the module folder) do

npm install ???

where ??? is the library noted in the message Cannot find module ‘???’

| in the example message above, ??? is request

to find this message, look in the output of npm start. or if you use pm2 to launch mm do
pm2 logs --lines=50

@oddo MagicMirror is written in Javascript, and uses loadable extensions (modules) to display small fragments of content (lots of modules, produces lots of content)

each module is essentially an application, focused on the content IT provides. without knowledge of any other module

the documentation on creating a module is here
https://docs.magicmirror.builders/development/introduction.html#general-advice

and u can use my sample to start
https://github.com/sdetweil/SampleModule

read the links in my signature below on how to install a module and making a good config file

also see my installation and maintenance scripts for MM
https://github.com/sdetweil/MagicMirror_scripts

@humdinger44 here u go

starting today, Sept 7, 2022, we have enabled posting moderation…

users with reputation less than 2 will have their posts dumped into the moderation queue for review before appearing in the forum.

this to stop the spam…

for existing users, to get your reputation raised requires someone to upvote your posts… think of helping new users we let in, after filtering out the spam

use the scripted upgrade if u have any additional modules…

https://github.com/sdetweil/MagicMirror_scripts#update-to-next-magicmirror-version-from-an-existing-magicmirror-installation

already seen requirement for npm rebuild or reinstall as a few have electron version dependencies (binaries) of THEIR dependencies

also note that valid-url has been removed, and at least two modules fail for this dependency

workaround

cd ~/MagicMirror
npm install valid-url

@egnos comma is continuation… its ok to have an EXTRA , after the play group,… it is NOT ok to have a missing , between things

as we get more users, we see the same errors occurring after each quarterly upgrade…

i have started a script to do this for the users…

lets collaborate and get it working…

I’ll maintain a copy on my dropbox…
https://www.dropbox.com/s/71xtxr18si7cpnq/upgrade-script.sh?dl=0

right now it doesn’t DO the npm installs… (flag for that)
we need to determine which files are important on the git pull ( i use fetch/diff to get the list of changed files)
and what to do about them… reset hard or stash /stash pop after…

know that package.json, package-lock.json and custom.css are files of concern so far…

it find all modules which have a package.json, and goes into each and does npm install if the base npm install works…

we know that some modules are difficult , because their electron version must match the base…
how can we detect that and run electron-rebuild…

always hate telling people to look, but where??

now its on the top bar.

@sdetweil probably node_helper missing

Do

cd ~/MagicMirror
git checkout modules/node_modules/node_helper/index.js

@jalibu as this a community constructed place, have at it. build whatever u want.

@lusiess01 ok, we have seen this only a few times… but in each case it was a problem with the memory card. stuff written doesn’t stick…

there is a problem with the original module… I have a fixed version
here https://github.com/sdetweil/MMM-GoogleMapsTraffic

Do this

cd ~/MagicMirror/modules
mv  MMM-GoogleMapsTraffic  MMM-GoogleMapsTraffic.original
git clone https://github.com/sdetweil/MMM-GoogleMapsTraffic
cd MMM-GoogleMapsTraffic
npm install

then restart the mirror app

@macg

where xxx is the library noted in the message cannot find module xxx

so your message was

 Cannot find module 'request'

so xxx is

request

just to clarify
there are MORE libraries not found than just request. so I am trying to teach you all how to read the messages and understand what to do…

Description

Enable MagicMirror sleep from external (camera) sources

If you are running the MM on a non PI device, or want to control sleep/wake without having to wire up another device, this module will take external info and signal MM to sleep or wake up.

I use a Webcam camera for the motion detection, driven by the github Motion project.
That project allows for a script to be run when motion starts and ends. I provide a script that
creates a file for both events, and the module detects those files.

the module supports sleep and wake 3 different ways… On PI using the tvservice command, or the exec dpms command if not using HDMI, or hiding all modules if using an energystar monitor (like my tv)

I have submitted changes to MMM-voice and HelloLucy to allow our modules to know about the others processing… so voice Go To Sleep and motion wakeup work… if using the Hide method, modules already hidden at sleep will remain hidden on wakeup.
