Slate v2 Legacy Example DX Ralplan

Current Verdict

Score: 0.91, status: ready-for-user-review.

Hard take: the legacy examples are drifting into two bad teaching patterns:

• too much lifecycle boilerplate for runtime stores;
• model behavior shoved into React event handlers because the extension/input API is not yet pleasant enough.

Do not paper over that by making Slate magically opinionated. Fix the reusable surfaces that examples are exposing.

This plan updates, but does not replace, the accepted initialization plan:

• React Editor Initialization And Value Ralplan

Intent And Boundaries

Intent:

• Keep raw Slate unopinionated while making examples feel first-class.
• Avoid teaching users to copy boilerplate that only exists because the public React helpers are missing one layer.
• Compare the example DX against Lexical, ProseMirror, and Tiptap without importing their full mental model.

Outcome:

• A concrete execution plan for six reviewed surfaces: editor history setup, checklist backspace behavior, code highlighting decorations, TypeScript inference cleanup, annotation store context, and void render props.
• No implementation in this pass.

In scope:

• .tmp/slate-v2/site/examples/ts/**
• .tmp/slate-v2/packages/slate-react/src/hooks/use-slate-editor.ts
• .tmp/slate-v2/packages/slate-react/src/decoration-source.ts
• .tmp/slate-v2/packages/slate-react/src/hooks/use-slate-annotations.tsx
• .tmp/slate-v2/packages/slate-react/src/components/slate.tsx
• .tmp/slate-v2/packages/slate-react/src/components/editable-text-blocks.tsx
• .agents/rules/ralph.mdc rule update, during execution only

Non-goals:

• Do not make slate-react depend on slate-history.
• Do not add Plate-like plugins to raw Slate.
• Do not resurrect public extension commands; the current hard cut rejects that surface.
• Do not claim any issue closure from this plan. This is DX/API cleanup.

Issue-ledger accounting:

• No Fixes #.... rows are added by this plan.
• Related issue pressure remains the existing decoration/annotation and React runtime clusters in Issue Coverage Matrix.
• If execution changes public APIs or example proof status, sync PR Description Reference.

Live Current State

Editor creation:

• useSlateEditor creates withReact(createEditor(editorOptions)) and only runs withEditor when provided: /Users/zbeyens/git/slate-v2/packages/slate-react/src/hooks/use-slate-editor.ts:23.
• CreateEditorOptions only carries initialValue and initialSelection: /Users/zbeyens/git/slate-v2/packages/slate/src/interfaces/editor.ts:616.
• slate-react has slate-history only as a dev dependency, not runtime dependency: /Users/zbeyens/git/slate-v2/packages/slate-react/package.json.

History examples:

• Many examples repeat withEditor: (editor) => withHistory(editor) as CustomEditor, for example code highlighting: /Users/zbeyens/git/slate-v2/site/examples/ts/code-highlighting.tsx:54.
• Simple examples can pass withEditor: withHistory, for example plain text: /Users/zbeyens/git/slate-v2/site/examples/ts/plaintext.tsx:6.

Checklist behavior:

• Checklists currently handle Backspace through Editable onKeyDown: /Users/zbeyens/git/slate-v2/site/examples/ts/check-lists.tsx:75.
• The handler calls model logic and returns true, which Editable treats as handled and prevents default: /Users/zbeyens/git/slate-v2/packages/slate-react/src/editable/keyboard-input-strategy.ts:74.
• The model behavior itself is currently helper-based, not extension-owned: /Users/zbeyens/git/slate-v2/site/examples/ts/check-lists.tsx:97.

Code highlighting:

• The example creates a decoration source with useMemo and manually destroys it in useEffect: /Users/zbeyens/git/slate-v2/site/examples/ts/code-highlighting.tsx:60.
• The public low-level factory is createDecorationSource(editor, options): /Users/zbeyens/git/slate-v2/packages/slate-react/src/decoration-source.ts:111.
• code-highlighting.tsx imports type Node as SlateNode only to annotate match callbacks: /Users/zbeyens/git/slate-v2/site/examples/ts/code-highlighting.tsx:25.

Annotations:

• Slate currently accepts annotationStores and composes their projection stores: /Users/zbeyens/git/slate-v2/packages/slate-react/src/components/slate.tsx:62.
• useSlateAnnotations still requires the store argument: /Users/zbeyens/git/slate-v2/packages/slate-react/src/hooks/use-slate-annotations.tsx:68.
• collaborative-comments.tsx passes the same store to <Slate> and then manually down to CommentList: /Users/zbeyens/git/slate-v2/site/examples/ts/collaborative-comments.tsx:540.

Void renderer props:

• renderVoid receives target, but that value is literally a Path: /Users/zbeyens/git/slate-v2/packages/slate-react/src/components/editable-text-blocks.tsx:456.
• The exported prop type is target: Path: /Users/zbeyens/git/slate-v2/packages/slate-react/src/components/editable-text-blocks.tsx:496.
• Examples then type the prop as target: Path and use it as at: /Users/zbeyens/git/slate-v2/site/examples/ts/images.tsx:119.

Ecosystem Evidence

Lexical:

• Core createEditor does not include history by default; vanilla examples register history explicitly with registerHistory: /Users/zbeyens/git/lexical/examples/vanilla-js-iframe/src/main.ts:38.
• React rich text adds <HistoryPlugin /> as a plugin: /Users/zbeyens/git/lexical/examples/react-rich/src/App.tsx:159.
• The newer extension path includes HistoryExtension explicitly in dependencies: /Users/zbeyens/git/lexical/examples/extension-vanilla-tailwind/src/main.ts:83.
• Checklist and tab behavior are registered as editor commands, not random app onKeyDown branches: /Users/zbeyens/git/lexical/packages/lexical-list/src/checkList.ts:68 and /Users/zbeyens/git/lexical/packages/lexical-extension/src/TabIndentationExtension.ts:83.

ProseMirror:

• History is a plugin with transaction metadata, grouping, and collaboration rebase behavior. It is not core editor default: /Users/zbeyens/git/prosemirror/history/src/history.ts:258.

Tiptap:

• StarterKit includes undo/redo by default and lets users disable it with undoRedo: false: /Users/zbeyens/git/tiptap/packages/starter-kit/src/starter-kit.ts:95 and /Users/zbeyens/git/tiptap/packages/starter-kit/src/starter-kit.ts:218.
• The lower-level extension registers ProseMirror history and keyboard shortcuts explicitly: /Users/zbeyens/git/tiptap/packages/extensions/src/undo-redo/undo-redo.ts:46.
• Keyboard behavior lives on extensions through addKeyboardShortcuts, which the extension manager turns into keymap plugins: /Users/zbeyens/git/tiptap/packages/core/src/ExtensionManager.ts:110.

Conclusion:

• Copy the explicit-history/preset split.
• Copy the extension-owned keyboard behavior.
• Do not make raw Slate silently include history.

Decision Brief

Principles:

• Raw Slate is unopinionated. Examples can be friendly; the core hook cannot lie about installed behavior.
• Runtime stores should have React lifecycle helpers when examples must create them before <Slate>.
• If a public prop is a Path, call it path. If the runtime wants a stable target, make it a real target object.
• TypeScript examples should teach inference, not cargo-cult aliases and casts.

1. History Default

Decision: do not put history in useSlateEditor by default.

Why:

• slate-react does not own slate-history at runtime.
• Lexical and ProseMirror keep history opt-in.
• Tiptap only defaults history inside an opinionated starter kit, not in the core editor.
• Collaboration often needs custom history. A hidden default would create accidental double-history and migration pain.

Target:

const editor = useSlateEditor({
  initialValue,
  withEditor: withHistory,
});

For custom behavior:

const editor = useSlateEditor({
  initialValue,
  withEditor: (editor) => withImages(withHistory(editor)),
});

Execution requirement:

• Fix withHistory generic preservation enough that common examples stop needing as CustomEditor.
• If the repo later creates a slate-starter package or example-only helper, that preset may include history by default and expose an explicit disable switch. Keep that out of raw useSlateEditor.

Rejected:

const editor = useSlateEditor({ initialValue }); // hidden history

That is convenient but wrong for Slate.

2. Checklist Backspace

Decision: the current onKeyDown move is mechanically safe but not the best DX.

Why it happened:

• v2 Editable owns keydown classification, composition, shell/virtualization repair, and default prevention. Returning true from a user keydown handler plugs into that runtime path.

Why it is not good enough:

• Checklist Backspace is model behavior, not a component event concern.
• App authors should not have to remember to wire onKeyDown every time they use checklists.
• Lexical and Tiptap put this kind of behavior in commands/extensions.

Target:

• Keep the current helper as a local safety bridge.
• Add an extension-owned keyboard/input capability for model behaviors that need key intent access.
• Implement checklist backspace through that capability or a typed withChecklists composer, not through per-example Editable onKeyDown.

Do not resurrect public extension commands. The v2 extension hard cut explicitly rejects public commands slots. Use capabilities or runtime input handlers.

3. Code Highlighting And Decoration Source Lifecycle

Decision: add a React lifecycle hook for decoration sources.

Current code is too much:

const codeHighlightingSource = useMemo(
  () => createDecorationSource(editor, options),
  [editor],
);

useEffect(
  () => () => codeHighlightingSource.destroy(),
  [codeHighlightingSource],
);

Target:

const codeHighlightingSource = useSlateDecorationSource(editor, {
  id: "code-highlighting",
  dirtiness: ["text", "node"],
  read: ({ snapshot }) => collectCodeProjections(snapshot.children),
  runtimeScope: ({ snapshot }) => collectCodeRuntimeScope(snapshot),
});

Rules:

• Keep createDecorationSource as the low-level API.
• Add useSlateDecorationSource in slate-react for the common React lifecycle.
• Do not hide dirtiness or runtimeScope; they are the performance contract.
• Reduce code-highlighting.tsx by extracting code-block editor behavior and projection source setup into named helpers.

4. TypeScript Inference In Examples

Decision: clean examples aggressively.

Current worst offender:

match: (n: SlateNode) => Node.isElement(n) && n.type === ParagraphType;

Target:

match: (node) => Node.isElement(node) && node.type === ParagraphType;

Execution:

• Remove useless type Node as SlateNode imports.
• Remove inline callback parameter types where the prop or API already infers them.
• Keep real exported component prop types where inference has no owner.
• Remove avoidable as CustomEditor, as any, and alias casts after composer typing is fixed. If a cast remains, it needs a local reason.
• Add this rule to .agents/rules/ralph.mdc, then run pnpm install because rules are source of truth.

Rule text to encode:

For TypeScript examples, prefer inference. Do not annotate callback parameters,
alias broad node types, or use `as any` / public type casts unless the compiler
cannot infer the public API shape. Prefer type guards, `satisfies`, and fixed
generic surfaces over local assertions.

5. Annotation Store Context

Decision: yes, the store should be consumable from Slate context, and the public provider prop should be singular: annotationStore.

Current shape passes annotationStores into <Slate>, but that is worse DX. One SlateAnnotationStore already stores many annotations through allIds and byId; channel/source distinctions should live in annotation data/projection, not in a plural provider prop.

Target:

<Slate annotationStore={annotationStore} editor={editor}>
  <CommentList />
</Slate>

const snapshot = useSlateAnnotations();

API shape:

• useSlateAnnotations() uses the nearest annotation store.
• useSlateAnnotations(store) remains valid for external sidebars, cross-editor inspectors, and explicit non-context reads.
• If no store exists, return the empty snapshot or throw in development based on the current hook philosophy.
• If a product really needs separate stores with independent lifecycles, expose an explicit composition helper or require the app to build one aggregate store. Do not make the common provider prop plural.

Do not put annotation stores on the core editor. They are React/projection runtime state, not document model state.

6. renderVoid Prop Name

Decision: rename public renderVoid prop from target to path, unless the value becomes a real target object first.

Current API says:

target: Path;

That is vague. If the value is a Path, the prop should be:

path: Path;

Future option, only if useful:

target: {
  path: Path;
  runtimeId: RuntimeId;
}

Do not keep target: Path as the stable v2 public API. It is worse for agents and humans because it sounds abstract while being less informative than path.

Execution Plan

Phase 1: History And Composer Typing

• Keep useSlateEditor history-free by default.
• Re-check withHistory and withReact generics.
• Remove casts from simple examples where generic preservation makes them unnecessary.
• Add type tests for withHistory preserving ValueOf<T> and editor intersections.

Acceptance:

• Examples can use withEditor: withHistory when no custom composer is needed.
• Custom composers do not require casts unless the custom editor type itself is intentionally broader than the runtime extension.

Phase 2: Checklist Behavior Ownership

• Keep current onKeyDown as baseline proof.
• Design a minimal extension keyboard/input capability that works with the v2 input runtime and composition guards.
• Move checklist Backspace into withChecklists or a checklist extension.
• Add focused tests around Backspace at start of a checklist item.

Acceptance:

• The checklist example does not manually wire checklist Backspace in Editable.
• IME/composition keydown behavior stays green.

Phase 3: Decoration Hook

• Add useSlateDecorationSource.
• Migrate code highlighting, search highlighting, external decoration sources, markdown preview, and highlighted text where the hook simplifies lifecycle.
• Keep low-level createDecorationSource exported.

Acceptance:

• No example manually pairs createDecorationSource with cleanup useEffect unless it is demonstrating the low-level API.
• Decoration store metrics and runtime-scope behavior stay unchanged.

Phase 4: Annotation Context Hooks

• Rename the public provider prop from annotationStores to annotationStore.
• Add annotation store context value derived from <Slate annotationStore>.
• Make useSlateAnnotations(store?) and useSlateAnnotation(id, store?) support context defaults.
• Migrate collaborative comments, review comments, and persistent annotation anchors where it removes prop threading.

Acceptance:

• collaborative-comments.tsx does not pass the same store through <Slate> and component props just to list annotations.
• One store can hold multiple annotation channels.

Phase 5: Void Prop Rename

• Rename RenderVoidProps<T>['target'] to path.
• Update examples and hooks that consume it.
• Decide whether to keep a temporary internal alias only if tests or examples need a migration bridge before public v2 freeze.

Acceptance:

• Public examples use path, not target, when passing at to transforms or useElementSelected.
• If a future stable object is introduced, it is named and typed as a real target, not a path alias.

Phase 6: Example Type Cleanup And Rule Sync

• Remove useless callback parameter annotations and alias imports from all examples.
• Remove avoidable casts after the API fixes above.
• Update .agents/rules/ralph.mdc with the TypeScript inference rule.
• Run pnpm install to sync generated skills/rules.

Acceptance:

• rg -n "match: \\(n: SlateNode\\)|type Node as SlateNode| as any| as CustomEditor" .tmp/slate-v2/site/examples/ts only returns justified leftovers.
• .agents/rules/ralph.mdc includes the inference rule.

Regression Proof

Required focused proof after implementation:

• bun --filter slate-react typecheck
• bun --filter slate-history typecheck
• focused Slate React tests for decoration source lifecycle
• focused annotation store hook tests
• focused checklist Backspace test
• focused examples typecheck or example-app typecheck
• browser smoke on:
  • /examples/check-lists
  • /examples/code-highlighting
  • /examples/collaborative-comments
  • /examples/images
  • /examples/embeds
  • /examples/mentions

Do not run full browser integration unless one of these focused rows points at runtime selection/input risk.

Maintainer Objections

"History should just be default. Everyone wants undo."

No. Everyone wants undo until collaboration, read-only, history-forking, or custom batching arrives. Lexical, ProseMirror, and Tiptap all keep the raw engine separate from the history plugin/extension. Slate should too.

"But examples are noisier without default history."

Correct. Fix the composer typing and example helper story, not the package boundary.

"Checklist behavior in onKeyDown is simpler."

It is simpler for one file and worse as the example people copy. Model behavior belongs to editor extension behavior, with React event hooks as escape hatches.

"Decoration hooks hide performance."

Only if they hide dirtiness and runtimeScope. The hook should hide lifecycle cleanup, not the invalidation contract.

"Annotation stores are external; hooks should take the store explicitly."

Explicit store arguments should remain. The default should use the nearest Slate context because <Slate annotationStore> is the editor-local projection channel.

"What if I have comments, suggestions, and review marks?"

Put them in one SlateAnnotationStore with a kind, channel, or source field. A store is already a collection. If independent lifecycles are truly needed, compose them before passing to <Slate>.

"target sounds future-proof."

Not while typed as Path. Future-proofing with a misleading name is fake design. Either call it path or make it a real target object.

Applied Skill Notes

• slate-ralplan: applied. This is a planning/review pass with live source grounding.
• intent-boundary-pass: applied. Intent, in-scope, non-goals, and issue boundaries are explicit.
• steelman-pass: applied. Maintainer objections recorded.
• high-risk-deliberate-pass: applied. Public API and runtime behavior changes are gated by proof.
• performance / performance-oracle: applied. Decoration invalidation and runtime store lifecycle keep dirtiness and runtimeScope visible.
• react-useeffect: applied. The plan removes repeated userland useMemo/useEffect cleanup ceremony behind a hook.
• tdd: applied as proof requirements, not implementation.

Score

Weighted score: 0.91.

Ready State

This plan is ready for a later ralph execution pass.

Do not start by implementing all phases at once. First execution should take Phase 1 plus one narrow example cleanup so type evidence is real before touching the rest.

Execution Log
