Clojure Ring auto-refresh script for error screen

Question

When :auto-reload? true :auto-reload? true , Ring injects an auto refresh <script> tag via its internal wrap-reload middleware whenever you return a status full HTML page. However, this auto-refresh script is not included when an error occurs. As a result, I have to manually refresh the page.

How can I tell Ring to inject an auto-refresh script into its error screen as well?

This is in my project.clj :

:ring {:handler my-app.handler/app
       :auto-reload? true
       :auto-refresh? true}

Answer 1

Since the auto-refresh is added to the successful response, perhaps it needs to also be added to the error response. You could add a custom error response that returns a 500 error whose body includes the auto refresh script.
