react-chatview

Infinite scroll chat or feed component for React.js

Changelog

Live Demo

Here is the live demo, and source code to the live demo, also here is a simpler fiddle.

Why another infinite scroll component?

As of time of this writing, other efforts are missing killer features:

• browser layout & resize "just works" (no need to know any heights in advance)
• Works as newsfeed (infinite load down) or chat (infinite load up)
• hardware accelerated scrolling

This work originated as a fork and modifications of seatgeek/react-infinite, and was subsequently rewritten several times.

Getting started

Install react-chatview using npm.

npm install react-chatview --save

You can also use a global-friendly UMD build:

<script src="path-to-react-chatview/dist/react-chatview.min.js"></script>

You can also use a es5 commonjs build:

<script src="path-to-react-chatview/lib/react-chatview.js"></script>

Documentation

It is really easy to use. The actual rows of content should be passed as children. There are four interesting props:

• className extra css class string for the container
• flipped true for chat (newest at bottom), regular for newsfeed (newest at top)
• reversed true for don't reverse elements
• scrollLoadThreshold pixel distance from top that triggers an infinite load
• shouldTriggerLoad callback function to check if chat view should trigger infinite load cycle when scroll passed scrollLoadThreshold. This callback is optional and by default onInfiniteLoad is always triggered.
• onInfiniteLoad load request callback, should cause a state change which renders more children
• returnScrollable return scollable object for scrollable event handling

See the jsfiddle example for a complete working example.

Todo

• Not actually infinite - currently all elements that have been loaded remain the dom

• auto-scroll to newest message when appropriate (pinning)

  use returnScrollable and set scrollable.scrollTop to scrollable.scrollHeight

• auto-correct scroll jitter when content resizes or is added above/below the focus point

• configurable loading spinner

• optimize for mobile (but it works)

There are probably more features missing. Please open an issue!

Please write me if you use this! :)

If this project is valued I will invest more time in it.
