MP3 Player

@sdetweil ah right so I need to change it to something like this:

MP3.setCurrentSong(0, 'songName');

Also did you manage to look into my later code which I described as the “better way”

sdetweil · Apr 18, 2024, 6:51 PM

@bachoo786 I did not look at the better method… cause I don’t know what that means.

I wasn’t looking at design, only syntax

@sdetweil ok I will try and explain the “better” method:

I’m basically trying to add a playlist feature to the MP3 player module I’m working on. My initial setup involved adding a songList to MP3Player.js, which lists all the songs—.mp3 files—in the ‘music’ folder of the module. I’ve also added a second folder, ‘music2’, to categorize songs by artist. Each artist’s name is tagged with an ‘h2’ in the CSS, for both songList and songList2.

However, this setup becomes cumbersome because it requires repeating the process for multiple artists, creating many folders and modifying the code each time for songList3, songList4, etc.

I thought a better approach would be to have one ‘music’ folder with subfolders for each artist containing their songs. This way, the module would display artists on the frontend, and clicking an artist’s name would show the songs in their folder.

I did start on this more streamlined method, but it proved challenging, so I reverted to the simpler, original method which we’ve been discussing since yesterday, as that uses a “single” songList displaying songs from the ‘music’ folder and has been working for me. So I have been trying to add another “songList2” to add more artists and their respective music.

I hope that makes sense?

@bachoo786 ok. I saw the song list 2 and 3, and said
these should be arrays of songlist[][]
but now that u add by artist it would be a hash of hashes
songlist{artist{album}{song}}

so you could access it with
songlist[“artistname”][“album1”][song1"]

or
songlist[song_info]
where song_info is a structure
{ artist_name:“…”, albums[{name:“…”, songs:[{…}]]}

@sdetweil sorry to mess with your head but I have been working on this for the last 3 hours and have come up with the following that should show the folders on the front end and when any folder is clicked it should reveal the mp3 files. the issue I am facing is that I am having no errors whatsoever but the module will just not show on the front end. I am pulling my hair out now !

these are my files:

node_helper.js:

var NodeHelper = require('node_helper');
const Fs = require('fs');

module.exports = NodeHelper.create({
    start: function() {
        console.log("Loaded MP3Player node_helper");
    },

    socketNotificationReceived: function(notification, payload) {
        var self = this;
        if (notification === 'SOURCE_MUSIC') {
            const musicPath = payload.musicPath;
            const extensions = payload.extensions;

            Fs.readdir(musicPath, (err, folders) => {
                if (err) {
                    console.error("Error reading music directory:", err);
                    self.sendSocketNotification('ERROR', {message: "Error reading music directory"});
                } else {
                    const musicData = folders.map(folder => ({
                        folderName: folder,
                        songs: Fs.readdirSync(`${musicPath}/${folder}`).filter(file => self.checkExt(file, extensions))
                    }));
                    self.sendSocketNotification("RETURNED_MUSIC", { musicData: musicData }); 
                }
            });
        }
    },

    checkExt: function(file, ext) {
        return ext.some(extension => file.toLowerCase().endsWith(extension)); 
    }
});

sdetweil · Apr 19, 2024, 1:09 PM

@bachoo786 can you please make a git repo of this.

sdetweil · Apr 19, 2024, 1:16 PM

@bachoo786 what shows in the developers window?

bachoo786 · Apr 19, 2024, 1:39 PM

@sdetweil I will .

Nothing says everything is loaded including the mp3 player module.

sdetweil · Apr 19, 2024, 1:47 PM

@bachoo786 well, code and data don’t match

config.js

        musicPath: "modules/MMM-MP3Player/music",

defaults

    musicPath: "modules/MMM-MP3Player/music",

getDom()

    if (MP3.config.musicData) { (and other places)

if you use the developers window you can step thru the code
