no-useless-use-spring

Reports spring hook calls whose config is static and whose dependencies never update.

Rule details Suggestion

By default, this rule checks useSpring. It reports calls where the config object is fully static and the dependency array is missing, omitted, or static. Empty dependency arrays are also reported by default.

Calls with both from and to in the config are skipped, because they can still represent a one-time mount animation.

Static springs still cost work

If a spring can never change, the hook is extra machinery around a constant value.

Options

Option	Type	Default	What it does
springHooks	string[]	["useSpring"]	Hook names treated as spring hooks
staticGlobalFactories	string[]	Roblox value constructors such as Vector3, UDim2, Color3, and CFrame	Names treated as static constructors
treatEmptyDepsAsViolation	boolean	true	Reports [] when the config is static

Examples

Incorrect

const spring = useSpring({ opacity: 1 });

const DEFAULT_SCALE = 1.5;
const scale = useSpring({ scale: DEFAULT_SCALE }, [DEFAULT_SCALE]);

Correct

const spring = useSpring({ opacity: isOpen ? 1 : 0 }, [isOpen]);

const intro = useSpring({
  from: { scale: 0 },
  to: { scale: 1 },
}, []);
