NodeRef

Sometimes we want to be able to reference a node in the DOM directly. We can do so by using NodeRef.

A NodeRef can be created by using create_node_ref. This can be assigned, in turn, to a node using the ref property in the view! macro.

let node_ref = create_node_ref(cx);

view! { cx,
    p(ref=node_ref) { "Hello World!" }
}

node_ref is now a reference to the p node.

We can access the raw node using the .get() method on NodeRef.

node_ref.get::<DomNode>()

Note that this method will panic! if the NodeRef has not been assigned to a node or if the NodeRef has the wrong type. That means that calling node_ref.get::<DomNode>() will panic! in a server side rendering context (which uses SsrNode instead of DomNode).
