Understanding the Role of <script> and <style> in Svelte
In a Svelte component, the <script> and <style> tags define the behavior and appearance of the component. Svelte files are self-contained, meaning that the logic, layout, and styling are all included in a single .svelte file.
Used to write JavaScript logic for the component, such as variables, functions, imports, and event handlers.
Supports reactive declarations using the
$:syntax, automatically updating the UI when variables change.Can import other components or external libraries.
Executed at compile time, producing optimized vanilla JavaScript.
Used to define the component's CSS styles.
Styles are scoped by default, meaning they apply only to the current component and not globally.
Helps keep styling modular and avoids CSS conflicts.
By combining <script> for functionality and <style> for presentation, Svelte enables developers to create highly modular and maintainable components.
