A unified interface to key/value stores.

Mnemonix aims to help you:

• Get running with key/value stores with minimal ceremony
• Experiment with different key/value store backends for your application
• Allow end-users of your library liberty to choose their preferred backend
• Enable composing access to different key/value stores with different read/write strategies

It encodes the behaviour, lifecycle, and feature set of a key/value store behind a common GenServer interface, normalizes different store APIs to conform to that interface, polyfills stores lacking features, and exposes access to them through a familiar Map API.

Learn more about starting a store and manipulating it with the Mnemonix API in the documentation.

Mnemonic systems are techniques or strategies consciously used to improve memory. They help use information already stored in long-term memory to make memorization an easier task.

Naturally, Mnemonix gives you Map-style functions to manipulate various key/value stores. However, Mnemonix also offers extra features beyond simple Map functions. Stores that don't natively support these features have the capability added through an Elixir polyfill, guaranteeing you can use and switch stores without worrying about what features they support under the hood.

Available features are:

• Mnemonix.Features.Map - The key/value manipulation you know and love
• Mnemonix.Features.Bump - Increment/decrement integer values
• Mnemonix.Features.Expiry - Set entries to remove themselves from the store with a ttl
• Mnemonix.Features.Enumerable - Iterate over all key/value pairs in supported stores

Add Mnemonix to your project's dependencies in its mix.exs:

def deps do
  [
    # ...
    {:mnemonix, "~> 0.10.0"},
    # ...
  ]
end

Pull requests are welcome and greatly appreciated!

Please submit them against the development branch rather than master––this allows useful changes to be finessed before release. The GitHub UI should do this by default.

Here are some useful commands if you've just forked the project and want to contribute:

• mix deps.get - Get development dependencies
• mix test - Run the test suite
• mix credo list - Run static code analysis for style pointers on Elixir source
• mix dialyzer - Run static code analysis for type checking on compiled BEAM bytecode
• mix coveralls.html - Generate test suite coverage report
• mix docs - Generate documentation pages
• mix inch - Evaluate quality of documentation
• mix checks - Run all of the above checks and analyses
• mix clean - If any of the above stop behaving as expected
