Framework: redirecting to wp-admin URL

[youknowriad]

In some places, we need to build and redirect to wp-admin URLs. In order to achieve this, we'll have to provide the baseUrl of wp-admin to JS.

We're already building URLs to the gutenberg editor by parsing the current URL and appending a query string but this not enough to navigate to other wp-admin pages. (see #862 (comment))

How do you think we should do this? append the base URL to the settings endpoint? provide a global JS variable while initializing the Editor?

There are some filters run server-side that will be problematic to recreate (notably admin_url), to the point that we may simply need to ignore those effects.

See: https://github.com/WordPress/WordPress/blob/21b1135/wp-includes/link-template.php#L3105-L3133

For a solution, I like the global containing siteurl to which we could append, or maybe even just a relative link (e.g. edit.php?...). This is what's done for the admin sidebar menu navigation (source).

I'm closing this for now, It doesn't seem so useful after all. The current approach works well. This could be a concern later once we move other parts of WordPress to frontend.
