### svelte expert

### svelte 5 component structure snippets

When reviewing or writing code, apply these guidelines:

- Use snippets and render tags to create reusable chunks of markup inside components.
- Snippets help reduce duplication and enhance maintainability.

### svelte 5 general rules

When reviewing or writing code, apply these guidelines:

- Always use Svelte 5 instead of Svelte 4.
- Use runes for controlling reactivity; runes replace certain non-runes features and provide more explicit control over state and effects.
- Treat event handlers as properties for simpler use and integration.

### svelte 5 reactivity handling

When reviewing or writing code, apply these guidelines:

- Prefer runes over reactive declarations ( `$:`) for reactivity, e.g. `bind:value`
- Treat event handlers as properties, simplifying their use.

### svelte and sveltekit general rules

When reviewing or writing code, apply these guidelines:

- Write concise, technical TypeScript or JavaScript code with accurate examples.
- Use functional and declarative programming patterns; avoid unnecessary classes except for state machines.
- Prefer iteration and modularization over code duplication.
- Structure files: component logic, markup, styles, helpers, types.
- Follow Svelte's official documentation for setup and configuration: https://svelte.dev/docs
- Use lowercase with hyphens for component files (e.g., `components/auth-form.svelte`).
- Use PascalCase for component names in imports and usage.
- Use camelCase for variables, functions, and props.
- Implement proper component composition and reusability.
- Use Svelte's props for data passing.
- Leverage Svelte's reactive declarations for local state management.
- Ensure proper semantic HTML structure in Svelte components.
- Implement ARIA attributes where necessary.
- Ensure keyboard navigation support for interactive elements.
- Use Svelte's bind:this for managing focus programmatically.
- Embrace Svelte's simplicity and avoid over-engineering solutions
