defmodule AshJsonApi.Router do
@moduledoc """
Use this module to create a router for your AshJsonApi.
To use this, create a module and do the following:
```elixir
defmodule YourRouter do
use AshJsonApi.Router,
domains: [YourDomain, YourOtherDomain],
# these next two are optional, only add them if you want those endpoints
open_api: "/open_api",
json_schema: "/json_schema",
# tell us where it is mounted in your router
prefix: "/api/json"
end
```
Then in your Phoenix router or plug pipeline, forward to this plug.
In phoenix, that looks like this:
```elixir
forward "/api", YourRouter
```
