Add JS Code to the Mirror

[stro]

No, i want to show the current playing Track from mopidy.

Either by MMM-MPD (i didn‘t get to work)
Or by the Code i found on the web ( i didn‘t get to work)

@stro MagicMirror is a web page.
It displays html. The modules generate a small section matching their requirements, and mm injects that onto the page in the configured position.

The module can get it’s data from anywhere. API, file system, database.

You have an API, which returns data, not html. Some code has to convert the data into displayable html

@sdetweil thanks for helping me.

I have the code (pastebin) who put the data, i‘m looking for, in a HTML Output. If i open the html file like this

file:///home/pi/MagicMirror/modules/test/mopidy.html

everything is okay.

But if open this HTML File with the Mirrorpath like this:

localhost:8080/modules/test/mopidy.html

It shows me nothing. And i wonder why.

@stro open the developers window, ctrl-shift-i, select the console tab and scroll up to see any errors

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:

alerts in MagicMirror 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>** 

Errors:

module in mm-config array looks like 
this.

{
		module: "mpd_client",
		position: "top_right",	// This can be any of the regions.
		config: {
			  // See 'Configuration options' for more information.
			hostname:"mpd@moodeaudio@rpi3b+=IPnumber)",
			port:6600 
			
		}
        
     },

@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…
