essentially I need to translate

import MomentUtils from "@date-io/moment";

<MuiPickersUtilsProvider utils={MomentUtils}>

Are you using a CJS or ESM distribution? I'll assume ESM for now, which in case you'll need to (require '["@date-io/moment$default" :as MomentUtils]) Assuming the utils prop accepts a function, then you should be able to use MomentUtils directly

Also, don't use aget with strings - it's intended only for arrays. When you need to get a field from a JS object that didn't come from goog.*, just use externs inference and interop: (.-someField ^js obj) (and ^js is not even necessary a lot of the times).

see all the examples translating import to CLJS require https://shadow-cljs.github.io/docs/UsersGuide.html#_using_npm_packages

(def moment-utils DateIOMoment/MomentUtils) is also preferred over aget. .- also works of course

or ["@date-io/moment$default.MomentUtils" :as moment-utils] as the shortest variant, just directly in require without any def
