We want to avoid avoid a potentially longer blocking page for the user due the time it takes to do the actual import. So the idea would be to dynamically submit the form with the POST data and edit token needed and then wait for a response in the background. Here's a rough plan on how this can be done.
- When clicking the submit button a handler set up by Codex UI stops the actual submission and triggers a POST request in the background to the special page with a flag to indicate a Codex submission
- An overlay with a spinner blocks the page as long as we wait for the response on that request https://doc.wikimedia.org/codex/latest/components/demos/progress-bar.html#using-progress-bars
- The Special page retrieves the submit request and executes the steps in doImport e.g. in a new method doCodexImport
- doCodexImport returns JSON that can be retried by the Codex UI to communicate the outcome of the import process
PoC:
- When the import is successful the Codex UI redirects to the result as it is now. When there's an issue we just show a generic error message.
