  • Each time the component is rendered with different prop values, a separate copy is saved to the cache.
  • If a component is frequently rendered with different prop values, you may prefer to cache a template of the component to save space in the cache.
  • To use the streaming functions, simply pass in these 5 arguments: ( : The React component being rendered : The component cache object : The response object that Express provides : Start of html markup in string form : End of html markup in string form ).
  • React Component Caching provides its own cache implementation as well as support for Redis and Memcached.
  • React Component Caching gives you access to all four of React 16’s server-side rendering methods, as well as additional functionality.

  • For example, you could do not the following before React@16 – class MyAwesomeComponent extends Component { – render () { – return ( – liItem One/li – liItem Two/li – liItem Three/li – ) – } – }You would have to wrap those elements.
  • – class MyAwesomeComponent extends Component { – render () { – return ( – span – liItem One/li – liItem Two/li – liItem Three/li – /span – ) – } – }This is a simple example but there could be many scenarios where you need to wrap your content.
  • But if you prefer the idea of returning an Array go right ahead – class MyAwesomeComponent extends Component { – render () { – return [ – liItem One/li, – liItem Two/li, – liItem Three/li, – ] – } – }Fragment is a solution allowing you to return many elements…
  • The content of the component will render as expected but without the wrapping – import React, { Component, Fragment } from ‘react’class MyAwesomeComponent extends Component { – render () { – return ( – Fragment – liItem One/li – liItem Two/li – liItem Three/li – /Fragment – ) – }…
  • – class MyAwesomeComponent extends Component { – render () { – return ( – – liItem One/li – liItem Two/li – liItem Three/li – / – ) – } – }The last thing to note is that Fragment only supports one attribute.
