Built on Battle-Tested Infrastructure

🔥 Ash Framework

Type-safe resources, declarative APIs, and automatic GraphQL/REST endpoints. Multi-tenant isolation built-in.

⚡ Phoenix LiveView

Real-time dashboards with zero-latency updates. Track type metrics and pattern match coverage live.

📊 Observable

Every type definition tracked. Compilation metrics, safety scores, and usage stats—all observable.

🗄️ PostgreSQL

Type metadata storage with full ACID guarantees. Query your type system like data.

# Define structured data (product types)
alkeymatter User do
  elements do
    reagent id :: String.t()
    reagent name :: String.t()
    reagent email :: String.t()
  end
end

# Define variant types (sum types) with Ash integration

  phases do
    essence Success, value :: any()
    essence Error, message :: String.t(), code :: integer()

  # Automatic Ash resource generation

    attribute :__variant__, :atom
    attribute :value, :map
    attribute :message, :string
    attribute :code, :integer
  end
  
  # GraphQL union types auto-generated
  graphql do
    type :result_union
  end
end

# Type-safe construction with observability
result = synthesize Result, response do
  {:ok, data} -> essence Success, value: data
  {:error, reason} -> essence Error, message: reason, code: 500
end
# ⚗️ Compilation time: 12ms | Safety score: 99.2%

# Type-safe pattern matching
message = distill Result, result do
  essence Success, value: data -> "Got: #{inspect(data)}"
  essence Error, message: msg, code: code -> "Error #{code}: #{msg}"
end
# ✓ Exhaustive pattern match verified at compile-time

Alchemical Metaphor

Transform data with intuitive alchemical terminology. Matter and form, essence and synthesis—concepts that make sense.

🔒

Type Safety

Catch errors at compile time with comprehensive type checking. No more runtime surprises from malformed data.

📊

Observable Everything

Every type tracked, every compilation measured. Real-time dashboards show safety scores and pattern match coverage.

🎯

Ash Integration

Automatic resource generation, GraphQL unions, and declarative APIs. Alkeyword types are first-class Ash resources.

Installation

Add Alkeyword and optional integrations to your mix.exs dependencies:

def deps do
  [
    {:alkeyword, "~> 1.0"},
    {:alkeyword_ash, "~> 1.0"},          # Ash Framework integration
    {:alkeyword_observable, "~> 1.0"},  # Real-time observability
    {:alkeyword_phoenix, "~> 1.0"}       # LiveView components
  ]
end

Then add to your modules:

defmodule MyApp.Types do
  use Alkeyword
  use Alkeyword.Ash          # Enable Ash integration
  use Alkeyword.Observable  # Enable metrics tracking
end

Quick Start (15 minutes)

# 1. Install Alkeyword
mix deps.get

# 2. Run migrations (sets up type metadata tables)
mix alkeyword.install

# 3. Start Phoenix with dashboard
mix phx.server

# 4. Visit http://localhost:4000/alkeyword/dashboard
#    See your types, metrics, and safety scores in real-time!
