I’ve been using Semantic UI with React & Meteor on my latest project and am finding they all work together remarkably well.
There are a few little gotchas as can be expected, but most of it just figuring out which part of the stack should take responsibility for things (e.g. using a Meteor ReactiveVar to keep track of what state an onboarding modal’s form is in so React can render the correct presentation, like a button showing loading indicator etc, and deciding on which Semantic UI callback to use to set that ReactiveVar). Sounds like it could be tricky but I’m finding it’s all very intuitive in practice. Surprisingly so, I haven’t had this much FUN developing with multiple new technologies in a long time.
So yes, highly recommend checking out Semantic UI, they even have React integration examples in their docs to help get you started.
