feat(core,react): public focus API with editor-UI-aware tracking - #3028
Merged
Merged
Conversation
`editor.isFocused()` and `onFocusChange` previously only saw the content area, so focus moving into the editor's own UI — a toolbar popover's input — read as a blur. That is fine for a desktop toolbar that unmounts anyway, but the mobile toolbar has to stay up while the user types a URL into the popover it opened. Adds an `includeEditorUI` option that treats the editor's UI as part of the editor, and defers the decision until focus has settled (at focusout the outgoing element has already lost focus and `document.activeElement` reads as `<body>`, so the destination isn't knowable yet). `useEditorFocus` exposes it as state for components that render off focus; `useEditorFocusChange` is the side-effect counterpart, the same split as `useEditorState` vs `useEditorChange`. The mobile toolbar controller switches to the hook, dropping its private reach into `editor._tiptapEditor`. The new hooks hold their callback in a ref so the subscription survives re-renders; `useEditorChange` and `useEditorSelectionChange` are converted to the same pattern for consistency. (Behaviour note: they no longer resubscribe when the callback identity changes — the latest callback is simply invoked.) The DOM contract this rests on is asserted rather than assumed — EventManager.browser.test.ts pins the documented focus event order, and that `document.activeElement` is `<body>` during focusout, across all three engines.
The document listeners behind `includeEditorUI` are reference-counted, and the returned unsubscribe decremented that count unconditionally. Calling it twice — which cleanup code does defensively — drove the count negative, so it never reached 1 again and the tracker silently stopped attaching for every later subscriber, with nothing to indicate anything was wrong. Proven across all three engines: subscribing after a double unsubscribe received no events at all. Also collapses the three near-identical copies of the `includeEditorUI` documentation into one exported `EditorFocusOptions` type, so the explanation has a single home rather than three that drift.
…acks The latest-ref wrapper called the callback with no arguments. The declared type never had any — so typed consumers are unaffected — but the subscription has always passed the editor, and an untyped caller using that argument would have silently received undefined. Forward it as before.

Review feedback: these test a specific hook, not an end-to-end flow, so they belong next to the source as a .browser.test file (they still need real focus semantics, so a browser rather than jsdom). Ported off the mantine BlockNoteView onto BlockNoteViewRaw and plain react-dom, since the react package cannot depend on a skin. Also from review: useEditorFocus now uses the EditorFocusOptions type the core API exposes (newly exported publicly) instead of restating it.
Review finding: the refs behind useEditorChange, useEditorSelectionChange and useEditorFocusChange were updated in a passive effect, so a layout effect firing an editor event right after commit could still reach the previous render's callback. The refs now update in an isomorphic layout effect — extracted from useEditorState, which already had the SSR-safe variant inline.

Review finding: the cached settled value initialized once, so changing the editor or includeEditorUI rendered one frame computed for the old inputs before the new subscription re-synced. The cache is now keyed by both inputs — an input change re-reads live, which is exactly what the first render already did. Proven red-first: flipping the option while focus sits in the editor's UI rendered a stale false frame on all three engines.

useEditorChange/useEditorSelectionChangeare converted to the same latest-ref pattern for consistency. They no longer resubscribe when the callback identity changes — the latest callback is simply invoked. Typed consumers can't observe a difference;useEditorSelectionChangekeeps forwarding the (undocumented) editor argument so untyped callers don't break.Tests
EventManager.browser.test.ts(12 tests × 3 engines) pins the DOM contract this rests on — the documented focus event order,<body>during focusout — plus dedupe, multi-editor independence, and unsubscribe semantics. Sabotage-checked: breaking the tracker's dedupe fails 2 tests on all 3 engines.useEditorFocus.browser.test.tsx(colocated with the hooks) covers them (15 tests).Summary by CodeRabbit
