Plato - Declarative Content Management

A learning project demonstrating Elixir umbrella applications, DSLs, and Phoenix.

🏗️ Umbrella Architecture

│   ├── plato/          # Core library (Schema DSL + Registry)
│   ├── plato_web/      # Phoenix web UI (optional)
│   └── plato_example/  # Example schemas

Quick Start

mix deps.get          # Install dependencies
mix test              # Run tests
mix phx.server        # Start server at http://localhost:4000

How It Works

1. Define schemas:

use Plato.DSL

schema "BlogPost" do
  field(:title, :text, required: true)
  field(:body, :text)
end

2. Get auto-generated web UI!

• Forms, validation, schema browsing - all automatic

Apps Explained

plato - Core library (no Phoenix dependency)

• Can be used in any Elixir project
• Just the DSL and Registry

plato_web - Optional web interface

• Depends on plato
• Provides Phoenix-based management UI

plato_example - Demo app

• Shows how to use Plato
• Defines example schemas

Why Umbrella?

✅ Core library stays clean and reusable ✅ Web UI is optional ✅ Clear separation of concerns ✅ Mirrors real-world Elixir apps
