DISCLAIMER: Personal thoughts only, based on what I’m seeing around the web over the last few years.
- If you’re trying to provide any custom functionality for WordPress, you pretty quickly end up doing it in PHP because that’s where all of the internal APIs and functionality resides.
That’s been a fine approach for the last 10 years, but I believe that things are changing, and we need to change with them to remain relevant. Full page reloads with heavy server-based everything is no longer really acceptable for a solid UX. With that in mind, here’s a possible future for WordPress, extrapolated out from where some things seem to be going (on the wider web, not necessarily currently within WordPress development):
Plugins would create additional endpoints within the backend API, or would supplement existing ones (e.g. post/meta) with additional data and/or actions. They could also be implemented via pure JS, depending on what they were built to do. Themes could potentially be built using no PHP at all — making queries directly to the API via JS, and then using something like Mustache to template the output back to the user. This would have SEO ramifications, but we can always figure something out there, and search engines are constantly improving.
Unfortunately a crucial point where backwards compatibility would be important would be the Post Editor, which is also where some big performance/UX improvements could potentially be seen by switching to a largely JS-powered UI.
I don’t know if this is really where WordPress will go, or if it is, exactly how it will get there. There’s a project currently to build a core REST API which I’m eagerly observing and will be trying to get more involved in. It has the potential to become the kernel of the future of WordPress if it’s done right. This is going to be a long road either way, so I’m excited for where we can all go from here.
Do you think WordPress can (or should) move in this direction?
