MountNode class

Lifecycle boundary node that triggers callbacks on mount and unmount.

Executes onMount after the child tree is attached to the DOM, and onUnmount when the subtree is removed or disposed.

DOM Mounting and SSR

  • Browser (mount): onMount is executed in a microtask immediately after DOM nodes are appended to the document. onUnmount is registered with the enclosing region and called when the region is torn down or rebuilt.
  • SSR (renderToHtml): Renders child only. Lifecycle callbacks onMount and onUnmount are intentionally ignored on the server.

Usually created using the DSL sugar Mount.
