ReactAutoHeaderList

Automatically create and render a list of items with headers to categorize them into sections/groups. You can think of it like the React version of iOS TableView with section header. ReactAutoHeaderList has zero dependencies, it only has peerDependencies for react.

Demo & Examples

Live demo: xkawi.github.io/react-auto-header-list

To build the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.

Installation

The easiest way to use react-auto-header-list is to install it from NPM and include it in your own React build process (using Browserify, Webpack, etc).

You can also use the standalone build by including dist/react-auto-header-list.js in your page. If you use this, make sure you have already included React, and it is available as a global variable.

npm install react-auto-header-list --save

Usage

Simply require them into your React component (or import is you support ES6 syntax). Refer to example/src for more details on how to use it.

var ReactAutoHeaderList = require('react-auto-header-list');

<ReactAutoHeaderList
    items={items}
    totalItemCount={items.length}
    onLoadMore={this.onLoadMoreClicked}
    isFetching={false}
    getSectionHeaderTitle={this.getSectionHeaderTitle}
    renderItem={this.renderItem}
    renderHeader={this.renderHeader}
/>

Properties

Required Props:

• items - array of items (e.g. [{}, {}, {}]);
• totalItemCount - number of items
• isFetching - boolean to indicate if data is being fetched, so it can show loading screen while fetching data asynchronously
• onLoadMore - function to load more data if items is fetch asynchronously
• renderItem - function to render the view of each item
• getSectionHeaderTitle - function to determine the section header title (e.g. first character of item.name), it will transform the items array accordingly

Optional Props:

• renderHeader(headerTitle) - function to render view for section header title
• renderLoadingView(isFetching) - function to render loading view when isFetching===true
• renderLoadMoreButton(onLoadMore, isFetching) - function to render 'load more' button
• renderEmptyView - function to render view when items.length = 0
• loadingLabel - string used in renderLoadingView (can be overwritten by renderLoadingView function itself)

Notes

ReactAutoHeaderList uses the totalItemCount props to determine if it needs to reset the transformed list or append to existing list when new data comes in. You can look at componentWillReceiveProps method on this business logic assumption.

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).

Roadmap

• replace 'load more' button with load data on scroll mechanism
• optimise rendering by only rendering views within the visible range of the viewport
• allow options to disable header
• replace or remove gulp with webpack or npm script
