From f5bcf363d2bcae0e8e571dd5e9ac9919093a886b Mon Sep 17 00:00:00 2001 From: Nick the Sick Date: Tue, 21 Oct 2025 11:49:45 +0200 Subject: [PATCH 1/3] fix(react): destroy editor instances after two ticks React's StrictMode makes it so that refs (which we use as the main trigger for mounting/unmounting the editor), are triggered twice. This makes it difficult to know when the editor is _actually_ meant to be unmounted. If an editor is unmounted during a render of React NodeViews, this can cause errors to occur (since elements which were in the dom at the start of the render are no longer in the dom by the time that the render occurs). This change takes a similar approach to the editor integration in Tiptap, where it delays `unmount`ing the editor until 2 ticks have passed. This is to allow React the opportunity to re-call `mount` with the same element, or if the ticks pass, to actually unmount the editor instance. In most cases, delaying the removal of the editor instance should be fine, because it is not expected to be available after it has been destroyed. --- packages/core/src/editor/BlockNoteEditor.ts | 31 +++++++++++++++++++-- 1 file changed, 28 insertions(+), 3 deletions(-) diff --git a/packages/core/src/editor/BlockNoteEditor.ts b/packages/core/src/editor/BlockNoteEditor.ts index 811e25afcc..14ce13b501 100644 --- a/packages/core/src/editor/BlockNoteEditor.ts +++ b/packages/core/src/editor/BlockNoteEditor.ts @@ -1035,15 +1035,40 @@ export class BlockNoteEditor< * @warning Not needed to call manually when using React, use BlockNoteView to take care of mounting */ public mount = (element: HTMLElement) => { - // TODO: Fix typing for this in a TipTap PR - this._tiptapEditor.mount({ mount: element } as any);
