Scroll-n-react

A react component library...

Description

Primary Objective

Scroll-n-react is a React Component Library for creating components that trigger functions at a certain scroll length. This is to create potentially infinite scrollers. There are other infinite scroller component libraries out ther but none that I have seen easily replicate features like the facebook messenger load more messages feature.

Demo TypeDocs

//Example you can check out in the example.tsx file. Just a real rough sketch of what using the component is like.
<ScrollRx onRef={ref => {this.child = ref}} height={300} loader={Wave2} threshold={0} width={250} getMore={this.Foo} anchorBottom component={K} fetching={this.state.fetching} dataArray={this.state.dataArray}/>

Props	Purpose	type
onRef	used to get a hold of the scroll instance to call its reset method	Function
height	Required prop that sets the height of the scroller	Number
width	Required prop that sets the width of the scroller	Number
threshold	Determines how far from the top or bottom that the scroller triggers its getMore callback	Number
getMore	The callback that should fetch more data via ajax or any other method, it should provide new props to the dataArray prop	Function
anchorBottom/anchorTop	Determines the orientation of the scroller. Anchorbottom makes it act a lot like facebook messenger's chat scrollers	boolean
dataArray	Array of objects.Each object MUST HAVE AN id property. This is used to coordinate the key feature and main motivation for this project. The id is used to hold a placeholder to the last top element after more data comes in instead of pulling your view up along with the new data.	{id: any}Array
component	Stateless component which will be filled with the data from dataArray	Function
fetching	prop you pass in that will display or hide the loader component. Use in tandem with getMore	Boolean
loader	A loader component that will show up when fetching is set to true. I provide a default Loader , but you can use something like react-better-spintkit to provide a better loader.	Function
