description	Dependency management patterns for the elixir_cache project. TRIGGER when: adding dependencies, modifying mix.exs, or changing project configuration. DO NOT TRIGGER when: working with code that doesn't involve dependency or project configuration.

Dependency Management

elixir_cache is a single Mix project (not an umbrella). All dependencies are declared directly in mix.exs.

Current Dependencies

Runtime:

• error_message — structured error returns
• redix + poolboy — Redis adapter backend
• con_cache — ConCache adapter backend
• nimble_options — option validation for adapter schemas
• sandbox_registry — process registry for test sandbox isolation
• jason — JSON encoding/decoding
• telemetry + telemetry_metrics — telemetry events

Optional:

• prometheus_telemetry — Prometheus metrics integration

Dev/Test only:

• credo + blitz_credo_checks — linting
• excoveralls — test coverage
• faker — test data generation
• dialyxir — static analysis
• ex_doc — documentation generation

Adding a Dependency

1. Add the dependency to defp deps in mix.exs
2. Run mix deps.get
3. If the dependency is only needed for a specific adapter, consider making it optional: true
4. Keep runtime deps minimal — this is a library published on Hex

Key Rules

• This is a published Hex package — be conservative with runtime dependencies
• Use optional: true for adapter-specific backends that consumers may not need
• Dev/test deps should use only: [:test, :dev] and runtime: false where applicable
• Keep mix.exs aliases: compile and test both use --warnings-as-errors
