React.ReactNode to react element

Question

I have an object of type React.ReactNode, and I want to:

1) Check if it is of type React.ReactElement

2) If yes, then I want to create a ReactElement Object equal to the node

for part 1, I am using React.isValidElement (not sure if necessary)

for part 2, i'm not sure how to do at all

In the end, I need to be able to check if a certain class is contained within the node if it is an element if that is of help. I'm assuming I need to create the ReactElement object to do this but if not that is okay as well.

Answer 1

First, you're using TypeScript (at least it looks that way by the tags) - so, ideally, you wouldn't even need to make a runtime check on the type of the object, you can do it at compile time

interface PropTypes {
  something: React.ReactElement<...>
}

const M = ({ something }: PropTypes) => { 

}

Second, in order to create a ReactElement from it, you can use React.cloneElement(...)

const cElement = React.cloneElement(something, something.props, [...children])
