[Solved]-How to prepare a React.js component for usage in ClojureScript as an external Reagent component?-Reactjs

Use ClojureScript's compiler options to include the external JS in the build, then use reagent's adapt-react-class to use the component in your reagent views. Try not to depend on projects like CLJSJS.

Doing this yourself will keep you in control of your project.

in project.clj

:foreign-libs [{:file "https://rawgit.com/felixrieseberg/React-Spreadsheet-Component/master/dist/spreadsheet.js"
                :provides  ["no-idea"]}]

in the views

(def reactable-table (r/adapt-react-class js/Reactable.Table))

(defn example []
  [:div
  [reactable-table
    {:data (clj->js [
                 {:name "Foo" :section 51}
                 {:name "Bar" :section 51}])}]])

Note however that this component bundles lots of dependencies (jQuery). You might be better of by making a component like this yourself, in clojurescript/reagent.
