npm version npm downloads Donate

A React component for scroll to #hash links with smooth animations. Scrollchor is a mix of Scroll and Anchor, a joke name for a useful component.

     * - this prop is required
    to: PropTypes.string.isRequired,

     * id attribute of the scrollable DOM node
     * - `#` can be omitted
     * - uses the root element of the document if omitted
    target: PropTypes.string,

     * scroll smooth animation can be customized
     * Accepted options, Ex: (default)
     *  { offset: 0, duration: 400, easing: easeOutQuad }
    animate: PropTypes.object,

     * callback function triggered before scroll to #hash

    disableHistory: PropTypes.bool

Reactive props

Update props will re-render Scrollchor element

Example: updating "to" prop

Custom animations

Animation behavior can be customized:

<Scrollchor to="#aboutus" animate={{offset: 20, duration: 600}} className="nav-link">Home</Scrollchor>

default animation settings

{ offset: 0, duration: 400, easing: easeOutQuad }

This setting is equivalent to default jQuery.animate easing: swing

more Easing functions

before and after Animate callbacks

Use these callbacks to trigger behaviors like: update state, load async stuff, etc.

<Scrollchor to="#aboutus" afterAnimate={() => updateState(this)}>Home</Scrollchor>

Simulate click API

Scrollchor includes a dedicate API to do animate scroll programmatically that works like normal click events using simulateClick().

Example: using simulateClick

When used programmatically, some use-cases don't need anchor tags. On these cases use childless Scrollchor.

Childless Scrollchor

This component will render null and the user is reponsible for storing the component reference, Ex: childless

<Scrollchor ref={ref => (this._back = ref)} to="_back" />

Example: calling simulateClick() on childless ref

_afterAnimate = () => {
  this.setState({ to: });
    setTimeout(() => this._back.simulateClick(), 1000);

Scrollable ancestor container

Scrollchor works within any scrollable parent container. The root element of the document will be choose if none is specified.

Hosted example show how to use a different container using prop target.
