react-native-section-alphabet: A TypeScript repository from Coffer

A simple React Native component that takes an array of data and renders a SectionList with alphabetically sorted data.

This package_uses the array of objects data-structure.

const data = [{...}, {...}, {...}, ...]

For react-native-flatlist-alphabet, the data does not need to be pre-formatted and sorted before use. The component handles all this logic internally.

Installation

Using npm:

npm install react-native-flatlist-alphabet

or with yarn:

yarn add react-native-flatlist-alphabet

Usage

Import the module

import AlphabetList from "react-native-flatlist-alphabet";

Use the component

<AlphabetList
  data={YourData}
  renderItem={YourRenderItemFunction}
  renderSectionHeader={YourRenderSectionHeaderFunction}
  getItemHeight={YourItemHeight}
  sectionHeaderHeight={YourHeaderHeight}
  indexLetterColor={ColorOfTheIndexSidebarLetters}
/>

YourData should be provided as an Array of objects, with each object item having both a valueand a key.

const YourData = [
  {
     value: string, // determines which alphabet section to place the object in
     key: string // used as the key in the keyExtractor for SectionList
     ... // your other properties
  },
  ...
]
