useControls brings is a smart GUI for your React apps and your creative coding endeavors:

• 🧐 Smart defaults, your GUI will always pick the best input type for your data
• 🤳 Mobile-ready, all inputs work perfectly on mobile
• 💪 Type safety, useControls is built from the ground up with typescript, all types are inferred from your code.

useControls isn't a component library.

• As-you-type filtering of inputs.
• You can modify number inputs by either dragging over the input label or inner label.
• The lib automatically calculates the number input step based on the initial value magnitude and significant digits.
• Increase / decrease numbers with arrow keys, with alt (±0.1) and shift (±10) modifiers support.
• Draggable pane.

• String
• Boolean
• Number
• Range
• Interval [min,max]
• Point2d [x,y] or {x,y}
• Point3d [x,y,z] or {x,y,z}
• Color #hex and {r,g,b,a}
• Select
• Spring {tension,friction,mass}
• Image

Simply call the useControls hook from anywhere in your app.

Your component will update whenever the values defined in the hook are changed!

import { useControls } from 'leva'

function MyComponent() {
  const { myValue } = useControls({ myValue: 10 })
  return myValue
}
