LiveDelegate

LiveDelegate helps split a Phoenix LiveView into smaller, composable modules without introducing LiveComponents or changing the normal LiveView lifecycle.

defmodule MyAppWeb.DashboardLive do
  use MyAppWeb, :live_view
  use LiveDelegate

  alias MyAppWeb.DashboardLive.Projects

  delegate(:projects, Projects)

  def mount(params, session, socket) do
    {:ok, socket |> delegate_mount(params, session)}
  end
end

defmodule MyAppWeb.DashboardLive.Projects do
  use LiveDelegate, path: [:projects]

  def on_mount(_params, _session, socket) do
    socket |> delegate_assign(%{items: []})
  end
end

LiveDelegate keeps related concerns together:

• Events are namespaced, such as "projects:add".
• Assigns live under the corresponding path.
• Submodules use familiar LiveView callback signatures and return values.
• A submodule can delegate further work to nested submodules.

See the LiveDelegate module documentation for the complete guide.
