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

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

Setup React with webpack 3, babel and NPM – Jakob Lind

How to setup React with webpack 3, babel and NPM  #reactjs #javascript

  • To get started with React you have to learn and configure NPM, webpack, babel AND React.
  • You have probably heard of create-react-app (CRA) which is an official tool to start a new React project.
  • Next, we are going to create our minimal React app and HTML file.
  • Our webpack config file looks like this: – – It contains the following: – – Babel is a highly configurable tool to transpile JavaScript.
  • Our webpack config uses babel-loader to run babel which uses the regular babel config file.

A few years ago jQuery was the best practice for Javascript/frontend development. Getting started with jQuery was as simple as creating an index.html document, include jQuery and start writing code.

Even Better Support for React in Flow – Flow – Medium

Even Better Support for #ReactJS in Flow:  by @calebmer #JavaScript

  • It is time to rethink how Flow models React.In Flow 0.53.0 we are changing how Flow models React and in doing this we can provide better types for higher-order components, strict typing for React children, and fixes for a host of bugs in Flow’s React support.The biggest change we are…
  • A React component in 0.53.0 looks like this:type Props = { foo: number,};type State = { bar: number,};class MyComponent extends React.ComponentProps, State { state = { bar: 42, }; render() { return this.props.foo + this.state.bar; }}When your component has no state, you only need to pass in a single type…
  • Without state your component definition would look like this:type Props = { foo: number,};class MyComponent extends React.ComponentProps { render() { return this.props.foo; }}If your component has default props then add a static defaultProps property:type Props = { foo: number,};class MyComponent extends React.ComponentProps { static defaultProps = { foo: 42, };…
  • For the React Router example above, you would type the Route component’s children as:type Props = { children: (data: { match: boolean }) = React.Node, path: string,};class Route extends React.ComponentProps { /* … */ }To learn more about typing React children read our documentation guide on the topic.The children prop…
  • Here is how you would type a simple higher-order component that injects a number prop, foo:function injectPropProps: {}( Component: React.ComponentType{ foo: number } Props,): React.ComponentTypeProps { return function WrapperComponent(props: Props) { return Component {…props} foo={42} /; };}class MyComponent extends React.Component{ a: number, b: number, foo: number,} {}const MyEnhancedComponent = injectProp(MyComponent);//…

The first version of Flow support for React was a magical implementation of React.createClass(). Since then, React has evolved significantly. It is time to rethink how Flow models React. In Flow 0.53…

How The React Framework is Changing Front-End Development

An Introduction to the #React Framework @reactjs #webdev

  • If you’re looking for instant page loads, or the ability to handle long lists of dynamic content changing within the view, React may be the JavaScript library for you.
  • Enter React, an isomorphic JavaScript library released by Facebook in 2013, that allowed developers to use SSR to build modern web apps.
  • One of the reasons developers had started to drift away from SSR was that it was necessary to have to load the entire web page every time something changed within the view.
  • React introduced a workaround called the Virtual DOM that allowed developers to take advantage of the inherent performance advantage of SSR, without having to update the entire view every time a user made a small change to the UI.
  • React is a powerful UI library that brings the power of SSR, isomorphic JavaScript, and component-based web development to modern dynamic web applications.

React (also known as React.js or ReactJs) is a powerful JavaScript library that uses server-side rendering (SSR) to provide a flexible, performance-oriented, componentized front-end solution. If you’re looking for instant page loads or the ability to handle long lists of dynamic content changing within the view, React may be the JavaScript library for you. Read on to learn more about React.
