Add JS Code to the Mirror

stacywebb

Check your

mopidy.conf

located at:

~/.config/mopidy/mopidy.conf

Look for this section:

[http]
enabled = true
hostname = 127.0.0.1
port = 6680
static_dir =
zeroconf = Mopidy HTTP server on $hostname
allowed_origins =
csrf_protection = true

Take note of the hostname part.
If your’s looks like the above instead of using localhost in the url, use the ip address or host name of the mirror.

Examples:
mirror.local:8080/modules/test/mopidy.html
or
10.x.x.x:8080/modules/test/mopidy.html

I tested the code you posted on pastebin and it works as expected for me.
Only tested using the hostname of the Mirror from external browser. Not locally on the machine.

I was able to solve that problem.
MPD port was double busy. Apparently 2 instances of Mopidy were running.

Now the module MMM-MPD runs under a few specials:

During the installation the folder name has to be changed according to the config file.
The config file value maxRows must not be 0!
The display will only update after a song change!

It was hard to find this specifics, but I thank everyone for the help!

Thank You @stro, This work great. Im rename folder MMM-MPD to mod_client and move to MagicMirror module, From MagicMirror/module/mpd_client npm install and work.

Something like this happens to me, but my module is from user coderpussy @github , pretty new fork, maybe I got some failure from moodeaudio devs, but I dont think, so anyway here is some of my errors.

if change folder name mmm-mpd to mpd_client errors in MM startup:

change folder name from mmm-mpd to mpd-client:
Result: No errors in MM-startup but mpd-module does not start.

**Looking for errors in MM-dev tools with folder named to mpd-module>**

module in mm-config array looks like 
this.

@dnj0104 there is probably more to the error message this also happens when there is some library required by a module not found at startup

u can also run

npm run config:check

to review any syntax errors in the config.js file

dnj0104

@sdetweil said in Add JS Code to the Mirror:

npm run config:check

in magicmirror/modules

or in magicmirror/modules/mpd-module ?

Thinks the whole module has to be rebuilt…

sdetweil

@dnj0104 in MagicMirror

dnj0104

@sdetweil

then I got

[2020-10-23 23:46:08.836] [INFO]   Checking file...  /home/pi/MagicMirror/config/config.js
[2020-10-23 23:46:09.049] [INFO]   Your configuration file doesn't contain syntax errors :)

sdetweil

@dnj0104 ok, so the error that causes the default config to load is caused by some other problem.

missing module, or some other failure

can u show the MM startup messages (from the window where you do npm start)

a module consists of the folder name

MMM-MPD

and its main js file

MMM-MPD.js

and inside MMM-MPD.js is the module register statement

Module.register("MMM-MPD", {

and in config.js

  {
     module: 'MMM-MPD',

this causes MM to look for the folder, filename and file contents in that order

SO, it SOUNDS like from a prior post, that the REAL name is

mod_client

(so there must be the right folder name, file name and file contents of
mod_client

if so, you can rename the folder (mv is the rename command on linux)
then in config.js you need

  module:'mod_client',

see the topic ‘How to add modules’ in my signature

mod_client

errors folder and file config.js (mmm-mpd) renamed to mod:

roll back, Folder named to mod-client and in config.js and mpd_client.js to mod_client.
Result; electron start with no error all my modules shows, but not mod_client aka mpd_client

sdetweil

@dnj0104 what MM version are you running on? this problem was fixed in 2.10
do this
from the MM folder

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

dnj0104

I got version 20.13.0

from your git command i get output

pi@raspberrypi:~/MagicMirror $ git checkout modules/node_modules/node_helper/index.js
error: pathspec 'modules/node_modules/node_helper/index.js' did not match any file(s) known to git

sdetweil

@dnj0104 can you do

cd ~/MagicMirror
grep version package.json

dnj0104

yes and and result is

pi@raspberrypi:~/MagicMirror $ grep version package.json
	"version": "2.13.0",

sdetweil

@dnj0104 yeh, mess

this module should be installed like this to make up for the name problem

cd ~/ MagicMirror/modules
git clone https://github.com/timjong93/MMM-MPD.git mpd_client
cd mpd_client
npm install

then everything matches

sdetweil

@dnj0104 thanks… so the git checkout would not have worked, sorry…

try the install as I suggest above

dnj0104

@sdetweil

so then i throw mpd client folder in trash and follow your
install instructions?

because I believe there have been a problem when I first installed mpd_client, I did not been clear where the npm install should been placed, if you read in mpd-client readme.md maybe you understand, english is not my first language, and my linux-fu is below first grade :)

sdetweil

@dnj0104 is ok, he didn’t do the instructions correctly…

yes, start over

cd ~/MagicMirror/modules
rm -rf mod_client

then do the install as I suggested

dnj0104

and then change folder name to mod-client ?

is it mod-client (folder) and mod_client in config.js in config array. do I also change name in mpd-client.js file?

sdetweil

@dnj0104 everythign should be named mpd_client

look at the files list in the module
https://github.com/timjong93/MMM-MPD

all mpd_client

no, do NOT change the folder name, change the config.js to match

module: 'mpd_client',
