ReactStickyHeadroom

ReactStickyHeadroom is a React component, that hides your header when you scroll down and shows it once you're scrolling up again. It's designed for best performance and can only be used if you know the height of your header component (or more precisely the amount of pixels you want ReactStickyHeadroom to hide). This helps us avoid calculating the height ourselves and therefore browsers don't need to perform heavy Recalculate-Style-Phases. For more information read here.

Since it's using styled-components internally, it's best to use it in apps where you already have styled-components in place. The component is only compatible with styled-components v4 and higher.

The component is inspired by react-headroom.

A basic usage example:

render () {
  return <StickyHeadroom scrollHeight={100}>
    <div style={{height: '100px', backgroundColor: 'red'}}>MyHeader</div>
  </StickyHeadroom>
}

You can pass the following props to ReactStickyHeadroom:

• children: React.Node The header component, that should be hidden and revealed
• scrollHeight: number The maximum amount of px the header should move up when scrolling
• pinStart: number (Default: 0) The minimum scrollTop position where the transform should start
• height?: number (Optional) The height of the children node. Used for calculating the stickyTop position for a sticky ancestor in onStickyTopChanged
• onStickyTopChanged?: (number) => void Fired, when Headroom changes its state and height is provided. Passes the calculated stickyTop position of an ancestor node.
• positionStickyDisabled?: boolean (Optional, Default: false) If true, the header will stay static (e.g. for edge 16 support)
• parent: ?HTMLElement (Optional, Default: document.documentElement) The parent element firing the scroll event.
• zIndex: number (Optional, Default: 1) The z-index used by the wrapper.
• className?: string (Optional) A classname for applying custom styles to the wrapper. Use at your own risk.

The component generally supports:

• Internet Explorer 11
• Edge >= 16
• Chrome >= 41
• Firefox >= 40
• Safari >= 6.2

However, if you want to support non-modern browsers, you are responsible for transpiling the code for your preferred target. The distributed files on npm are transpiled for ES2020.

For hiding and revealing the header, the browser needs to support the css-property position: sticky. You can read about the browser support for that on caniuse.com. 'Partial-Support' is enough for ReactStickyHeadroom to work in most cases.

Since version 2.x.x, ReactStickyHeadroom is written in TypeScript. Support for FlowJS types were dropped in version 2.0.0.

ReactStickyHeadroom is a client-side library and hence does not support Server Side Rendering (SSR) a priori. For NextJS you can find more information on how to embed this library here.
