I’m saying that I’m using Typescript to create a React APP that uses OnsenUI.
In implement the OnsenUI components it’s necessary the react-onsenui types for the best typescript experience, but not all of the components are typed.
npm install @types/react-onsenui --save-dev
Brings this: https://github.com/DefinitelyTyped/DefinitelyTyped/blob/master/types/react-onsenui/index.d.ts
And if you take a look, you will not find Checkbox or SearchInput (to name a few) react-onsenui components.
I hope it makes sense
