Data, conditions & styling

  • Conditional rendering: "visible": {"auth": "signed-in"}, {"roles": ["admin"]} or an expression such as "=product.stock > 0". Decided on the server: hidden elements are never sent.
  • Data binding: bind takes text from data (name, user.name, props.title, params.slug, state.cart.count); binds binds attributes. Containers become data-driven with data + item. See data binding.
  • Styling: className for your stylesheets, style for CSS in JSON, states for hover/focus/active, animation for entrance motion. See the style property reference.
  • Responsive behaviour: responsive applies CSS at or below a breakpoint ({"mobile": {"padding": "12px"}}); grids also take responsiveColumns.
