Use The Wizard

Editing JSON by hand is tedious. All the json config options can be edited by using the cli wizard. To use it:

mstream --wizard /path/to/config.json

JSON config

Using a JSON config with mStream allows for more advanced configurations. This example contains all configurable params for reference purposes.

{
  "port": 3030,
  "webAppDirectory": "public",
  "secret": "b6j7j5e6u5g36ubn536uyn536unm5m67u5365vby435y54ymn",
  "writeLogs": true,
  "noUpload": false,
  "scanOptions": {
    "skipImg": true,
    "scanInterval": 1.5,
    "pause": 50,
    "saveInterval": 500,
    "bootScanDelay": 15
  },
  "storage": {
    "albumArtDirectory": "/media/album-art",
    "dbDirectory": "/media/db",
    "logsDirectory": "/media/logs"
  },
  "folders": {
    "blues": "/media/music/blues",
    "rock": { "root": "/media/music/rock"}
  },
  "users": {
    "paul": {
      "password":"p@ssword",
      "vpaths": ["blues", "rock"]
    },
    "james": {
      "password":"qwerty",
      "vpaths": "rock",
      "lastfm-user": "username",
      "lastfm-password": "password"
    }
  },
  "ssl": {
    "key": "/path/to/key.pem",
    "cert": "/path/to/cert.pem"
  }
}

All these params have default values. Technically, an empty objects would be valid. It's the same as running mstream without any config options

# This is valid
{ }

Port

Sets the port. Defaults to 3000 if not set

UI

Folder that contains the frontend for mStream. Defaults to public if not set

Secret

Sets the secret key used for the login system. If this is not set, mStream will generate a random secret key on boot and previous login sessions will be voided

Scan Options

• skipImg: (boolean) whether to skip scanning for album art. Speeds up the scan time
• bootScanDelay: delay between server boot and first file scan (in seconds)
• scanInterval: The interval which controls how often file system will be scanned for changes (in hours)
• saveInterval: interval which to refresh the DB on scan. Defaults to 250. Can be set to a higher number for large collections to avoid hogging the CPU thread
• pause (in milliseconds): During the scan, there is an optional pause that is aded between file parsing. This can prevent mStream from hogging system resources during the initial scan

{
  "scanOptions":{
    "skipImg": true,
    "scanInterval": 1.5,
    "pause": 50,
    "saveInterval": 500,
    "bootScanDelay": 15
  }
}

Folders

Folders are set by key value pairs. The key is used later to give access to folders on a per user basis. (more info in the users section)

There are two valid syntaxes for folders

  "folders": {
    "blues": "/media/music/blues",
    "rock": { "root": "/media/music/rock"}
  }

For now, these are identical. In the future, mStream will be able to offer different frontend features based on the directory type.

Users

A basic user example.

{
  "folders": {
    "media": "/media/music"
  },
  "users": {
    "paul": {
      "password":"p@ssword",
      "vpaths": "media"
    }
  }
}

A user with multiple folders

{
  "folders": {
    "music": "/media/music",
    "audiobooks": "/media/books/audio"
  },
  "users": {
    "paul": {
      "password":"p@ssword",
      "vpaths": ["music", "audiobooks"]
    }
  }
}

Multiple users with multiple directories

{
  "folders": {
    "jake-music": "/media/jake/music",
    "finn-music": "/media/finn/music",
    "audiobooks": "/media/books/audio"
  },
  "users": {
    "jake": {
      "password":"p@ssword",
      "vpaths": ["jake-music", "audiobooks"]
    },
    "finn": {
      "password":"p@ssword",
      "vpaths": ["finn-music", "audiobooks"]
    }
  }
}

If there is no users object, the login system will not be enabled and anyone will be abe to access the server. All folders will be accessible

{
  "folders": {
    "music": "/media/music",
    "audiobooks": "/media/books/audio"
  }
}

SSL

mStream comes with SSL support built in. Just add your key and cert and the server will take care of the rest

  "ssl": {
    "key": "/path/to/key.pem",
    "cert": "/path/to/cert.pem"
  }

Disable Uploading

  "noUpload": true

LastFM Scrobbling

Each user can have their own lastFM credentials

{
  "folders": {
    "jake-music": "/media/jake/music",
    "finn-music": "/media/finn/music",
    "audiobooks": "/media/books/audio"
  },
  "users": {
    "jake": {
      "password":"p@ssword",
      "vpaths": ["jake-music", "audiobooks"],
      "lastfm-user": "username",
      "lastfm-password": "password"
    },
    "finn": {
      "password":"p@ssword",
      "vpaths": ["finn-music", "audiobooks"],
      "lastfm-user": "username",
      "lastfm-password": "password"
    }
  }
}

If you want to use LastFM scrobbling without a user system, you can do the following

{
  "folders": {
    "music": "/media/music",
    "audiobooks": "/media/books/audio"
  },
  "lastfm-user": "username",
  "lastfm-password": "password"
}

Port Forwarding

Set tunnel to true if you want mStream to try to auto configure port forwarding via uPNP

{
  "tunnel": true
}

Storage

mStream will write, logs, DB files, and album art to the filesystem. By default these will be written in the mStream project folder tothe save and image-cache folders. Use the storage object to choose where to save these files

The albumArtDirectory will be publicly available

{
  "storage": {
    "albumArtDirectory": "/media/album-art",
    "dbDirectory": "/media/db",
    "logsDirectory": "/media/logs"
  }
}

Logs

set writeLogs to true to enable writing logs to the filesystem

  "writeLogs": true,
