Lastfm Archive Build Status Hex pm Coverage Status

A tool for creating local Last.fm scrobble data archive and analytics.

The software is currently experimental and in preliminary development. It should eventually provide capability to perform ETL and analytic tasks on Lastfm scrobble data.

Current Usage

Download and create a file archive of Lastfm scrobble tracks for a configured user via Elixir applications or interactive Elixir (invoking iex -S mix command line action while in software home directory).

  LastfmArchive.archive

The data is currently in raw Lastfm recenttracks JSON format, chunked into 200-track compressed (gzip) pages and stored within directories corresponding to the years when tracks were scrobbled.

The data is written to a main directory specified in configuration - see below.

Requirement

This tool requires Elixir and Erlang, see installation details for various operating systems.

Installation

lastfm_archive is available in Hex, the package can be installed by adding lastfm_archive to your list of dependencies in mix.exs:

  def deps do
    [
      {:lastfm_archive, "~> 0.1.0"}
    ]
  end

Documentation can be found at https://hexdocs.pm/lastfm_archive.

Configuration

Add the following entries in your config - config/config.exs. For example, the following will create a file archive for a_user. The archive will be written to ./lastfm_data/a_user/ within the software home directory.

An api_key must be configured to enable Lastfm API requests, see https://www.last.fm/api (“Get an API account”).

  config :lastfm_archive, 
    user: "a_user", # lastfm user name
    data_dir: "./lastfm_data/", # main directory for the archive
    per_page: 200, # 200 is max no. of tracks per call permitted by Lastfm API 
    req_interval: 500 # milliseconds between requests cf. Lastfm's max 5 reqs/s rate

  config :elixirfm,
    lastfm_ws: "http://ws.audioscrobbler.com/",
    api_key: "", # mandatory
    secret_key: ""
