🇺🇸United States @phillamb168

phillamb168 → created an issue.

Figured it out... pushed to the fork: https://git.drupalcode.org/issue/preview_link-3273377/-/compare/2.1.x......

I needed this functionality as well. I modified the functionality on PreviewLinkController::preview() so that it:
1. checks entity->status->value to see if it's published
2. if published, calls the sessiontokencontroller and removes the tokens (to avoid redirect loops)
3. redirects to the new entity URL.

I'm pasting in the patch file while I figure out how to submit a patch - it's been a while so I need to remember how to do it.

Poking on this one - would be good to get it in, I had a similar issue and the patch resolved it for me.

I figured this out - it's actually pretty easy. On your local machine, run the drush command. Then what I did was:

create a new directory in the project root `ckeditor-plugins`
copy the `ckeditor5` directory from `web/libraries` (or wherever your docroot is) to this folder.
Your directory structure should now look like this:
/composer.json
/composer.lock
/web/libraries/ckeditor5/plugins/media-embed/build/media-embed.js (there are a lot of other files in /web/libraries/ckeditor5 but that's the important one)
/ckeditor-plugins/ckeditor5/plugins/media-embed/ (again lots of other files here)

You'll want to get composer to handle the copy of course - I added the following to my composer.json file:

    "scripts": {
        "post-update-cmd": [
            "cp -R ckeditor-plugins/ckeditor5 web/libraries/ckeditor5"
        ],  
        "post-install-cmd": [
            "cp -R ckeditor-plugins/ckeditor5 web/libraries/ckeditor5"
        ]
    }, 

Your 'scripts' section may look slightly different - just add those two cp commands as necessary.

@elusivemind thank you for this. One issue I'm experiencing: on Pantheon, we're not allowed to run drush commands that modify libraries because the filesystem is read-only. I thus need to have the media-embed part of ckeditor5 installed via composer. I'm digging into the docs for the ckeditor5 core side of things, but do you have any leads on how to install the requirement without having to run the drush command?
