@firere/roact-spring v1.1.3-ts.1

Why roact-spring

Declarative and imperative

roact-spring is the perfect bridge between declarative and imperative animations. It takes the best of both worlds and packs them into one flexible library.

Fluid, powerful, painless

roact-spring is designed to make animations fluid, powerful, and painless to build and maintain. Animation becomes easy and approachable, and everything you do look and feel natural by default.

Versatile

roact-spring works with most data types and provides extensible configurations that makes it painless to create advanced animations.

Getting Started

Getting started with roact-spring is as simple as:

Declarative

local toggle, setToggle = React.useState(false)
local styles = RoactSpring.useSpring({
    transparency = if toggle then 1 else 0,
})

-- Later
setToggle(function(prevState)
    return not prevState
end)

Imperative

local styles, api = RoactSpring.useSpring(function()
    return {
        position = UDim2.fromScale(0.3, 0.3),
        rotation = 0,
    }
})

-- Later
api.start({
    position = UDim2.fromScale(0.5, 0.5),
    rotation = 45,
    config = { tension = 170, friction = 26 },
})
