Add JS Code to the Mirror

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

@sdetweil said in Add JS Code to the Mirror:

mod_client

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

@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
