Server-driven admin for the Ash framework

Your resource in.
A whole admin out.

Mishka Gervaz reads an Ash resource and generates the Phoenix LiveView admin (tables, forms and everything around them) from a short DSL. No hand-written UI.

How it works

From resource to admin in three moves.

Point at a resource

Add the DSL to any Ash resource. Gervaz reads your attributes, actions and relationships.

Declare tables & forms

A few lines describe columns, filters, fields and layout. Field types and options are inferred from Ash.

Get a live admin

Mount its LiveComponent in a LiveView: sortable, filterable, validated, uploads and real-time.

Tables

Columns, sort, filters, pagination, bulk & row actions, archive, all declarative.

Forms

22 field types: text, select, upload, relation, nested maps, combobox and more.

Wizards & tabs

Split a form into steps, wizard or tabs mode, with one layout block.

Validation

Driven by your Ash actions. Field-level errors surface automatically on change.

Real-time

Wire pubsub and rows update live. No manual subscriptions, no polling.

Uploads

Drop-zone or button, multi-file, auto-namespaced, existing-file management.

URL state

Filters, sort, page and search load from the URL; set mode :bidirectional and copy-link just works.

Overrides

Change one callback, wire a module, or swap a whole subsystem. No fork.

Pluggable UI

Same DSL, any design system.

The render layer is a swappable adapter. Tailwind ships in, Mishka Chelekom drops in, your own kit slots in. Mix them per resource or per component.

# tailwind ships in — your domain's default
mishka_gervaz do
  table do
    ui_adapter MishkaGervaz.UIAdapters.Tailwind
  end
end

# chelekom's components, tailwind for the rest
defmodule MyAppWeb.UIAdapter do
  use MishkaGervaz.Behaviours.UIAdapter,
    components: MyAppWeb.Components,
    nested_components: true
end

# in a resource's table or form block
presentation do
  ui_adapter MyAppWeb.UIAdapter
end

# your own kit — override only what you need
defmodule MyAppWeb.UIAdapter do
  use MishkaGervaz.Behaviours.UIAdapter
  def button(assigns), do: MyAppWeb.Kit.button(assigns)
end

Multi-tenant

One DSL, two actors.

The same admin drives a different Ash action depending on who's signed in. Master users act across every tenant with restore & soft-archive rights; tenant users see only their own scope. Toggle the actor →

Honest comparison

Why Mishka Gervaz for Ash admin panels.

Mishka Gervaz turns an Ash resource into a Phoenix LiveView admin: tables, filters and forms from one DSL. Here is how it compares with LiveAdmin, Backpex and Cinder.
