Caravela
Declare your domain. Sail with the generated code.
A schema-driven, composable full-stack framework for Phoenix projects. Describe a domain (entities, fields, relations, hooks, permissions) as an Elixir DSL; Caravela generates Ecto schemas, migrations, Phoenix contexts, JSON controllers, Absinthe schemas, and LiveView + typed Svelte components.
defmodule MyApp.Domains.Library do
use Caravela.Domain, multi_tenant: true
version "v1"
entity :books do
field :title, :string, required: true, min_length: 3
field :published, :boolean, default: false
end
can_create :books, fn ctx -> ctx.current_user.role in [:admin, :editor] end

Status
Phases 1–5 are in place: DSL + compiler, Ecto schemas + migrations,
hooks + permissions, Phoenix contexts, JSON API, Absinthe/GraphQL,
multi-tenancy, API versioning, LiveSvelte generation, the
Caravela.Live.* runtime, dynamic Svelte forms with visibility
predicates + async validation, and a GenServer-backed flow runtime
(Caravela.Flow) for composable async workflows. Phases 7–8 add
trait-based authentication — declare authenticatable on an entity
and mix caravela.gen.auth emits the full email/password + API-token
stack plus matching LiveSvelte UI. Phase 9 adds triple-target
policies — one policy block compiles into Ecto WHERE clauses,
field projection on every API/GraphQL response, and a typed
field_access Svelte prop, all enforced server-side.
