What’s New With Server-Side Rendering in React 16 – Hacker Noon

What’s New With Server-Side Rendering in React 16:  by @xander76 #JavaScript #ReactJS #NodeJS

  • Naturally, this feature is also supported by React 16’s server-side rendering.So, you can now server-render components that look like this:class MyArrayComponent extends React.Component { render() { return [ div key=”1″first element/div, div key=”2″second element/div ]; }}class MyStringComponent extends React.Component { render() { return “hey there”; }}class MyNumberComponent extends React.Component {…
  • To learn more about this feature, read Dan Abramov’s post on the React blog about the change.React 16 SSR Doesn’t Support Error Boundaries or PortalsThere are two new features in the React 16 client-side renderer that are unfortunately not supported in the server-side renderer: Error Boundaries and Portals.
  • If for any reason there’s a mismatch, React raises a warning in development mode and replaces the entire tree of server-generated markup with HTML that has been generated on the client.In React 16, though, the client-side renderer uses a different algorithm to check that the server-generated markup is correct.
  • And when the client-side renderer in React 16 detects a markup mismatch, it only attempts to change the HTML subtree that doesn’t match, rather than the entire HTML tree.Generally, this change shouldn’t have much effect for end users, except for one fact: React 16 doesn’t fix mismatched SSR-generated HTML attributes…
  • This performance optimization means that you will need to make extra sure that you fix any markup mismatch warnings you see in your app in development mode.React 16 Doesn’t Need To Be Compiled For Best PerformanceIn React 15, if you used SSR straight out of the box, performance was less…

There are lots of exciting new bits (most notably the Fiber rewrite), but personally, I’m most excited about React 16’s many improvements that have been made to server-side rendering. Let’s take a…

Write Your Own React.js! – Caleb Meredith – Medium

Write Your Own React.js! @calebmer  #Reactjs #JavaScript #WebDev

  • One of the more popular React alternatives (at least in my Twitter feed) is Preact which shares a very similar API to React.
  • Even React Fiber , the React core team’s experimental rewrite of React internals is just another set of implementation details on top of the core abstraction!
  • After you have your VDOM implementation and optional JSX transformer, all that’s left is defining the interface.
  • Including Lin Clark’s “A cartoon guide to performance in React” or Paul O’ Shannessy’s “Building React From Scratch” .
  • Depending on your use case filesize matters, and React made that tradeoff for features over filesize.

Meditation is incredibly difficult for me. First, I sit down. Second, I do some stuff with my arms and legs that I’m sure looks “zen.” Third, I’ll start deep-breathing, or what I think is deep…
