I think at this point Mediawiki's frontend stack and its dependencies on RL and supporting user gadgets don't lend itself well to frameworks like React or Vue. With regards to moving away from jQuery UI your path of least resistance inside MediaWiki feels like it might be to use a library such as Redux for managing your state and OOjs UI for rendering the UI components.
Frameworks by definition provide you with rules and constraints to prevent you from writing code in bad ways leading you to easier to work with code. The MediaWiki ecosystem doesn't do well with constraints - it's about experimenting. That aside, I'm curious if you have considered a different approach. One big issue we commonly see in the reading web team in working with MobileFrontend and our apps team who depend on our APIs is that the lines of model and view get blurred frequently. There are certain things our API doesn't do and that we workaround in PHP code - the only place we can do this. I was a little worried about this, so as a side project I explored how difficult it was to render the existing mobile site without MediaWiki's PHP layer. I built a progressive web app (PWA) using React (just a personal preference but any framework could be used to do the same). The result is deployed on labs: https://trending.wmflabs.org and the code on Github: https://github.com/jdlrobson/weekipedia At first, this may seem like a lot of work but it wasn't. I reused Mediawiki code where possible (packaging up into npm libraries) and what I found was feature development became extremely easy the more that I implemented as reuse was extremely useful within the framework. The React web app now has feature parity with the mobile site - it looks th esame, you can login support via OAuth (thanks to the awesome work from Gergő Tisza and co), there's i18n support <https://trending.wmflabs.org/he.wikipedia/%D7%99%D7%A9%D7%A8%D7%90%D7%9C?uselang=he>, you can edit.... you can view history/diffs etc etc... we've been using it for user testing. Since things got so easy I even got carried away and built features I've wanted forever ;-) [1]: If I exclude the time I spent improving Mediawiki REST APIs to support this app I reckon building this took about a month of work (and that wasn't even full time). Yes, the solution had many trade-offs... My app cannot run gadgets or CSS/JS from the Mediawiki namespace and certain pages which require additional JavaScript e.g. maps/pages with math do not load that Js - but I see those problems as easily solvable and I value the benefits I experienced through working within a well-documented framework... So I'm curious... for something like Wikidata which is so different from standard Mediawiki instances =(the rendering and editing experiences are fundamentally different) what's stopping you from adding a layer on top of the stack and using Mediawiki as a black box for storage and API... at least as an alternative editing experience? Having complete APIs and enabling our future and present community members to be able to build things like this easily should be our goal as engineers. It's worth pointing out that Chrome has plans to allow developers to package web apps as installable APKs (see https://joreteg.com/blog/installing-web-apps-for-real). What this means is with a bit of configuration I could update my PWA to override all visits to Wikimedia domains and steal traffic. I think when this happens lots of developers will be jumping on this opportunity. This is great for distributing our knowledge, not so good about keeping a unified experience for all our visitors. I'd rather we were ahead of that trend rather than lagging behind. Happy to chat more if you find this conversation interesting. I've covered a lot here... :) [1] e.g. * infinite random - https://trending.wmflabs.org/en/wiki/Special:Random * the trending work turned into a REST API that we're still experimenting with and offline support. * cross-wiki search - https://trending.wmflabs.org/en.wikiquote/Special:Search/San%20Francisco On Tue, 31 Jan 2017, 5:06 a.m. Jan Drewniak, <jdrewn...@wikimedia.org> wrote: Certainly a topic for the front-end standards group, but to give my two cents: Many of these new JS libraries, such as React, have some very heavy dependancies. React requires JSX which needs to be transpiled into JS, ES6 Class syntax which needs to be transpiled into ES5, which requires Babel and probably a task runner like Grunt or Gulp (or webpack), which of course require Node and NPM... so already you've built a very heavy dependancy chain which itself needs to be maintained (ex: Gulp 4 is coming with breaking changes) and all this needs to be integrated into MediaWiki which has its own way of doing things. None of that sounds like fun to me, so however you proceed I would certainly aim to avoid all that <https://getpocket.com/a/read/1434444086>.
