Hello,
I have an e-commerce site and I migrated the site’s search results pages to use LiveView. Users can paginate the search results, and the liveview uses push_patch to update the url with a page param like fakestore.com/search?page=1
I want to be able to canonicalize the search results pages such that fakestore.com/search?page=1 or fakestore.com/search?page=2 or fakestore.com/search?page=n… all point to the same canonical url.
I am having a difficult time figuring out how to add a rel=canonical link to the head of the page. The LiveView in question inherits from a root.html layout that stores all of the static metatags, but I can’t simply put the rel=canonical in root.html because that root layout is shared across many other pages, and I only want the rel=canonical to apply to the search results page.
What is the best method for passing information from a LiveView to the layout?
One idea I have is ditching the live "path" LiveView call in the router and instead use regular controllers/templates. Then, in the controller, I would be able to pass some information about rel=canonical to the conn, and pull that information off of the conn in the root layout. Then I could use live_render to render the liveview from within the controller. However, I would really prefer to avoid making changes like these just for this use case.
Thanks for the help!
