Three presentational pieces that turn a bare text area into a document editor: EditorTabs (the open documents, like a code editor's tab strip), EditorStatusBar (word and character counts, line and column, and whether the text is saved) and EditorBacklinks (documents that link here, and related ones). You own the text and the state; the chrome shows it and reports what the person did.

When to use

  • A notes or writing app where several documents can be open at once.
  • Any editor that autosaves and needs a calm, always visible save state.
  • Knowledge tools that link documents to each other.

When not to use

  • Page-level navigation: use tabs (Base UI tabs, panels included). EditorTabs has no panels; the editor is yours.
  • Editing the rich text itself: use rich-text-editor.
  • A list of every note: use notes or EntityList.

Import

import { EditorTabs, EditorStatusBar, EditorBacklinks } from "@fadymondy/nasaq/web";
// inside this monorepo: "@nasaq/web"

Quick start

import { useState } from "react";
import { EditorBacklinks, EditorStatusBar, EditorTabs, closeEditorTab, editorCursorAt, editorTextStats } from "@fadymondy/nasaq/web";

export function Editor() {
  const [tabs, setTabs] = useState([
    { id: "a", title: "Trip plan", dirty: true },
    { id: "b", title: "Ideas" },
  ]);
  const [active, setActive] = useState<string | null>("a");
  const [text, setText] = useState("Book the flights");
  const [caret, setCaret] = useState(0);
  const stats = editorTextStats(text);
  const { line, column } = editorCursorAt(text, caret);

  return (
    <div className="flex flex-col">
      <EditorTabs
        tabs={tabs}
        activeId={active}
        onSelect={setActive}
        onClose={(id) => {
          const next = closeEditorTab(tabs, active, id);
          setTabs(next.tabs);
          setActive(next.activeId);
        }}
      />
      <textarea value={text} onChange={(e) => setText(e.target.value)} onSelect={(e) => setCaret(e.currentTarget.selectionStart)} />
      <EditorStatusBar words={stats.words} characters={stats.characters} line={line} column={column} saveState="saved" />
    </div>
  );
}

Examples

<EditorTabs tabs={tabs} activeId={active} onSelect={setActive} onClose={close} onNew={createDoc} onPin={pin} onCloseOthers={closeOthers} onCloseAll={closeAll} />
<EditorStatusBar saveState="error" onRetry={retrySave} words={120} characters={640} line={4} column={12} />
<EditorBacklinks
  backlinks={[{ id: "1", title: "Weekly review", snippet: "…see [[Trip plan]] for dates…", path: "Journal" }]}
  related={[{ id: "2", title: "Packing list" }]}
  highlight="Trip plan"
  onOpen={(link) => open(link.id)}

Accessibility

KeyAction
Arrow keysMove between tabs (Left and Right swap in RTL).
Home, EndFirst and last tab.
Enter, SpaceSelect the focused tab.
DeleteClose the focused tab (when onClose is set).
Shift+F10, Menu keyOpen the tab's context menu.
  • The strip is a tablist with a roving tab stop. A dirty tab has visually hidden text "Unsaved changes", not only a dot.
  • The save state is a role="status" live region; the error state is role="alert". Every state has an icon and text, never colour alone.
  • Localise labels when the app has its own wording.

RTL & i18n

  • The strip, arrows and counts follow the Nasaq direction. Left and Right arrows swap in RTL.
  • Counts use the locale's formatting with Latin digits by default. Document titles use dir="auto".
  • Line and column labels are localised ("Ln 4" and "سطر 4").

Styling & tokens

Uses --nq-* surface, border, selected and focus tokens. Target data-slot, and data-active and data-dirty on tabs. Extend with className.

Do / Don't

  • Do keep the save state visible. Autosave without feedback makes people press Ctrl+S anyway.
  • Do close a tab and move to its neighbour (closeEditorTab does this).
  • Don't use the tab strip for navigation between app sections.
  • Don't hide a failed save behind a toast. The status bar keeps it in view.
