Loader

Picking a variant

All 7 variants (ring-inset, ring-clip, ring-outset, ring-dual, pulse, dots-roll, dots-sweep) are real, distinct animations, not palette swaps of the same shape — ring-inset (the default) reads as a standard spinner; the dots variants read lighter and work well inline next to text; pulse is the least visually busy option for a subtle "something's happening" indicator.

<Loader variant="ring-inset" />
<Loader variant="dots-roll" size="sm" />
<Loader variant="pulse" color="primary" />

Color: one prop or two

color is a shorthand that sets both the track and the moving indicator to the same color in one step — the common case. For a variant where the track and indicator should differ (a light track with a colored indicator, for instance), set trackColor and indicatorColor independently instead of using color.

<Loader color="primary" />

// Independent track/indicator colors
<Loader trackColor="default" indicatorColor="success" />

Sizing and speed

size accepts the usual xs–xl token scale, or a raw pixel number when you need an exact footprint that doesn't map to a token (say, matching an icon's exact size next to it). speed takes any valid CSS time value if the default 1s animation cycle feels off for the context — slower for a background sync, faster for something the user is actively waiting on.

<Loader size="sm" />
<Loader size={18} />
<Loader speed="0.6s" />

Inside a Button

For a loading button, you almost never render Loader directly — pass isLoading to Button and it renders its own internal spinner (with spinnerPlacement/spinner to customize it) already wired to aria-busy. Reach for a standalone Loader when the loading state belongs to a section of the page, not a specific button.

// A loading section, not a button -- standalone Loader
<div className="flex items-center justify-center p-10">
  <Loader label="Loading dashboard" />
</div>

Accessibility

• Renders with role="status" so assistive technology treats it as a live region announcing an in-progress state.
• label (defaults to "Loading") supplies the accessible name announced alongside role="status" — override it with something more specific ("Loading dashboard", "Saving changes") whenever there's more than one loading region on a page, so a screen reader user can tell which one just started or finished.

Best practices

• ◆Always keep label meaningful when a page has more than one Loader at once — the default "Loading" text is fine for a single, obvious spinner, but ambiguous if several regions can be loading simultaneously.
• ◆For a button's own loading state, use Button's isLoading prop instead of manually rendering a Loader inside it.
• ◆Match variant weight to context: dots-roll/dots-sweep read lighter for inline or small-scale use; ring-inset/ring-outset read as a more standard, higher-visibility spinner for full-section loading states.
• ◆Don't rely on Loader alone to communicate what's loading — pair it with surrounding text or a label prop, since a lone spinning icon carries no information by itself.
