A plug for responding to "ready" check requests.

This plug responds with "200 YES" when ready, "423 NO" otherwise. It checks the :ready_for_traffic env var to determine if the application is ready for traffic.

Options

• :otp_app - app name that the config belongs to
• :path - request path string to handle requests for
• :json - a boolean to decide whether response should be json

Examples

defmodule MyServer do

use Plug.Builder
plug Fast.Plug.Ready

# ... rest of the pipeline

end

Using a custom path:

defmodule MyServer do

use Plug.Builder
plug Fast.Plug.Ready, otp_app: :my_app, path: "/ready"


# ... rest of the pipeline

end
