A simple React component that lets you listen for when scrolled to the bottom


A simple listener component that invokes a callback when the webpage is scrolled to the bottom.






npm install react-bottom-scroll-listener

yarn add react-bottom-scroll-listener


On bottom of entire screen

Simply have the BottomScrollListener anywhere in your application and pass it a function as onBottom-prop.

<BottomScrollListener onBottom={callback} />

On bottom of specific container

Pass the BottomScrollListener a function inside the JSX_tag, receive the scrollRef in this function from the BottomScrollListener
and pass it to the component you want to listen for a scroll event on.

<BottomScrollListener onBottom={callback}>
  {scrollRef => (
    <div ref={scrollRef}>
      Callback will be invoked when this container is scrolled to bottom.

Those are some weird children, what's going on?

This pattern is called "function as a child". What this allows is that the BottomScrollListener can pass you a React.RefObject. This
React.RefObject can then be passed to whatever component you want to be notified when you hit the bottom of. Without this it would be
difficult to attach event listeners for scrolling to an arbitrary element.


Property Type Default Description
onBottom Function null (required): callback invoked when bottom is reached
debounce number 200 milliseconds, how much debounce there should be on the callback
offset number 0 offset from bottom in pixels. E.g. 300 if it should invoke onBottom 300px before the bottom.
children React.Node or Function null Not required, but you can use this to wrap your components. Most useful when you have some conditional rendering. If this is a function, that function will receive a React.RefObject that needs to be passed to a child element. This element will then be used as the scroll container.
