Notes

You might find this library useful if you are an Elixir developer who needs to work with the Discogs API in some form.

It includes Ecto mappings for the Discogs User -> Release -> Record and Artist -> Release -> Record relationships, and could be easily extended.

I kept the Ecto model structs quite slim, since I originally wrote this repo for a fairly simple use-case (creating a shuffled sample of records to experiment with aleatory DJ mixes).

Here are a few more reasons this library might be of interest to Elixir developers:

• as an example of a tested Ecto library that does not include Phoenix
• as an example of a library using the uncommon sqlite_ecto2 adapter
• as an example of a CLI app making very minimal use of Elixir's OptionParser

Contributing

This project uses credo and formatter for style consistency. Please run

mix format

Guidelines

Testing

All public functions for the Ecto models should be tested exhaustively, including changeset/2.

Documentation

All public modules and their functions should be documented with the appropriate typespecs.

This library uses ExDoc conventions for documentation. You can run

mix docs

to build the docs and open them in your local environment.

Typespecs are validated through dialyzer.
