solid-infinite-scroll

Infinite scrolling / Dynamic list loading library for SolidJS

Installation

First, install the library from the npm registry:

yarn add -D solid-infinite-scroll

Second, import it in the tsx component you're working on:

import InfiniteScroll from 'solid-infinite-scroll';

Usage

To use the infinite scroll module, you would need a signal/resource for data storage, and implement two functions:

• each should return the currently stored data array, this is similar to the SolidJS <For> component
• hasMore should return true if more data is available
• next should load more data into the array stored by each and return nothing

For example, if you want to load all data at once but only display e.g. 50 at a time, you can do:

const fetchApi = async () => await (await fetch("https://api.example.com/list").json() as string[]

export default function App() {
  const [api] = createResource(fetchApi)
  
  const [scrollIndex, setScrollIndex] = createSignal(50)
  const scrollNext = () => setScrollIndex(Math.min(scrollIndex() + 50, api().length))
  
  return (
    <InfiniteScroll each={api()?.slice(0, scrollIndex())} 
      hasMore={scrollIndex() < api()?.length}
      next={scrollNext}>
      {(item, index) =>
        <div>{item}</div>
      }
    </InfiniteScroll>
  )
}
