React + TypeScript + Vite

This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.

Currently, two official plugins are available:

• @vitejs/plugin-react uses Babel for Fast Refresh
• @vitejs/plugin-react-swc uses SWC for Fast Refresh

Expanding the ESLint configuration

If you are developing a production application, we recommend updating the configuration to enable type aware lint rules:

• Configure the top-level parserOptions property like this:

export default {
  // other rules...
  parserOptions: {
    ecmaVersion: 'latest',
    sourceType: 'module',
    project: ['./tsconfig.json', './tsconfig.node.json'],
    tsconfigRootDir: __dirname,
  },
}

• Replace plugin:@typescript-eslint/recommended to plugin:@typescript-eslint/recommended-type-checked or plugin:@typescript-eslint/strict-type-checked
• Optionally add plugin:@typescript-eslint/stylistic-type-checked
• Install eslint-plugin-react and add plugin:react/recommended & plugin:react/jsx-runtime to the extends list

Side Panel Focus Pattern

We use a consistent focus management pattern for side panels:

• Open: focus the first actionable element inside the panel.
• Close: restore focus to the button that opened the panel.

Implementation summary:

1. A provider stores a panelRef and a registry of trigger refs (setTrigger/getTrigger).
2. Each trigger button registers itself with setTrigger("key", el).
3. Panel content uses useRestoreFocus with:
   • resolveTrigger → returns getTrigger("key").
   • onOpened → finds the first actionable element inside panelRef.

Example:

// Trigger button
;<ToggleButton ref={(el) => setTrigger('tools', el)} />

// Panel content
useRestoreFocus(isOpen, {
  resolveTrigger: (activeEl) => getTrigger('tools') ?? activeEl,
  onOpened: () => {
    const first = panelRef.current?.querySelector(
      '[data-attr="tools-list"] button'
    )
    ;(first as HTMLElement | null)?.focus({ preventScroll: true })
  },
})
