This plugin is excellent and works exactly as advertised. Definitely worth a perfect rating.
I do think the FAQ could be expanded a little more to mention process_cache_relations for custom REST endpoints, however. I only found my solution buried in other users’ threads. I had wrongly assumed that providing the object type manually via the determine_object_type hook was equivalent to making object relationships work, which is clearly not the case.
Overall, a really great plugin and very well thought-out.
Using this plugin has made my API for filtering products go from finishing the filtering and reaching the user in 2.3 seconds to reaching the user in about 200 ms. A huge improvement indeed.
However, I’ve noticed two things that slowly drive me insane:
This is a solid 5/5 if they add the above. I’ve yet to find a better solution that doesn’t involve Cloudflare.
Thanks for the plugin!
Installed on suggestion of WP Maps, made a big difference in load speeds of maps.
Great plugin! I use it for a headless WordPress instance with Nuxt 3, and it works perfectly fine.
The only thing I needed to change was the API endpoint since I created a custom endpoint to the route. But the FAQ cleared this up quickly and it works flawlessly. As a small suggestion I’d propose to add this option to the plugin’s settings page for easier access.
