I want entries in a specific PlainText field for a named group to be pre-filled with random content. I am aware of the https://github.com/lukeyouell/craft-randomkeygenerator plugin and am aware that I could create my own field type, but I am intending to use jQuery to do this instead (which should be easier).

This Can a plugin add JS or CSS to the control panel? describes how to do this in Craft 2 (I assume that the code works). My equivalent in Craft3 is... 

class MyPlugin extends Plugin {
    if (Craft::$app->request->getIsCpRequest())
    {
      Craft::$app->templates->includeJs('alert("xxx")');
    }
}

but $app->templates does not work. So is there a Craft3 equivalent of this line?

NB: I have already written a plugin that is adding a file volume (for encrypting files uploaded as Assets) so intend to add to that.

You should be able to do this with Asset Bundles. Full documentation on this is here.

Thanks for those. I found out for the specific need I had that I could take the existing Craft3 Plaintext field file, duplicate it (in my plugin folder), change the 'value' line of the getInputHtml function and then add a EVENT_REGISTER_FIELD_TYPES event to the main Plugin file.

However, there are other situations where I may need to add Javascript so I have reviewed the Asset Bundle page, but I will not be able to check it in detail until a specific job requires its use.

I hope this 'answer' matches the guidelines as it (strictly) does not answer my original question (only its need).
