somascrobbler-api

SomaScrobbler API Server streams SomaFM track metadata in real-time over socket.io. SomaFM's metadata contains a lot of errors and typos, so the data is auto-corrected and enhanced using Last.fm's correction API.

Note: This is also available as a service

SomaFM is probably not too happy if a thousand people poll their API about several dozen thousand times per day. So if you intend to run this software locally just for you, it might be better to use api.somascrobbler.com instead of running your own.

The service can be used for free as much as you want. There is, however, no up-time guarantee or any other type of guarantee or warranty. But we try our best. If you notice that the service is having problems, please just submit an issue.

Installation

• Download and install Node.js or io.js. You should use a recent version.
• Then install the somascrobbler-api package globally (-g) from npm. You may have to prefix the sommand with sudo depending on your setup.

npm install somascrobbler-api -g

Configuration

Create a config file "$HOME/.somascrobblerapirc" or "/etc/somascrobblerapirc", or any other location supported by the rucola module.

Here's a sample config file:

loglevel = debug

[somafm]
pollinterval = 20000

[lastfm]
apikey = xx123456789012345678901234567890

[server]
address = 0.0.0.0
port = 9987
uri = http://localhost:9987

• loglevel (string; optional; default: info): The log level. Can be either "debug", "info", "warn", or "error".

• somafm.pollinterval (integer; optional; default: 10000): The number of milliseconds to wait between SomaFM API requests.

• lastfm.apikey (string; optional; default: null): Your Last.fm API key. This is required for metadata auto-correction. If omitted metadata will not be corrected and contain lots and lots of typos.

• server.address (string; optional; default: 0.0.0.0): The IP of the interface for the web server to listen on. By default it will listen on all interfaces.

• server.port (integer; optional; default: 9987): The port for the web interface to listen on.

• server.uri (string; optional; default: http://localhost:9987): The full public URL through which the web interface will be accessible including the port number unless you're using one of the default ports.

Configuration options can also be provided through environment variables. For example, the valirable key for lastfm.apikey would be SOMASCROBBLERAPI_LASTFM_APIKEY.

Run

somascrobbler-api

Or provide an alternate config file:

somascrobbler-api --config=path/to/theconfig

Additionally, configuration options can be overridden through command-line arguments:

somascrobbler-api --lastfm-apikey=blabla_my_lasfm_key

Docker

SomaScrobbler API Server is also available as a Docker image. It should work with Docker 1.5 or later.

Pull the image from the registry:

docker pull maxkueng/somascrobbler-api:latest

To run it, provide all non-default configuration options as environment variables:

docker run -d \
  -p 80:9987 \
  -e SOMASCROBBLERAPI_LASTFM_APIKEY=xx123456789012345678901234567890 \
  -e SOMASCROBBLERAPI_SERVER_URI=http://example.com \
  --restart on-failure \
  maxkueng/somascrobbler-api:latest

You can also mount an external config file instead of using environment variables (or use a combination of both):

docker run -d \
  -p 80:9987 \
  -v /path/to/the/config/file:/etc/somascrobblerapirc \
  --restart on-failure \
  maxkueng/somascrobbler-api:latest
