View Source Commanded.Commands.CompositeRouter (Commanded v1.4.1)
Composite router allows you to combine multiple router modules into a single router able to dispatch any registered command from an included child router.
One example usage is to define a router per context and then combine each context's router into a single top-level composite app router used for all command dispatching.
example
Example
Define a composite router module which imports the commands from each included router:
defmodule Bank.AppRouter do
use Commanded.Commands.CompositeRouter
router(Bank.Accounts.Router)
router(Bank.MoneyTransfer.Router)
end
One or more routers or composite routers can be included in a
Commanded.Application
since it is also a composite router:
defmodule BankApp do
use Commanded.Application
router(Bank.AppRouter)
end
You can dispatch a command via the application which will then be routed to the associated child router:
command = %OpenAccount{account_number: "ACC123", initial_balance: 1_000}
:ok = BankApp.dispatch(command)
Or via the composite router itself, specifying the application:
:ok = Bank.AppRouter.dispatch(command, application: BankApp)
A composite router can include composite routers.
