  • The < Route > component is one of the most useful components of React Router v4 and the idea behind it is simple, wherever you want to render something when only there is a match with the location’s path you can use a Route component.
  • We can just append the name to be used for the variable plus a colon : to the end of the route’s path, for example: – – When there is a path match an object which has the following properties will be created and passed to the component: – -…
  • First we import the necessary routing components such as Route and BrowserRouter – – Next we create the base layout component, besides common HTML tags we also use React Router v4 components Link and Route: – – Next we create our pages: – – And finally we create the App…
  • In our example app we used the prop exact in the Route for component HomePage – – That’s because React Router v4 uses inclusive routing instead of exclusive routing used by React Router v3 so without exact property the home component will be rendered with all other components, for example…
  • You can also navigate inside your React application using methods from the history object, for example: – – Which are equivalent to: – – Whenever you want to redirect to another location, you can place component which is when rendered will redirect to the location specified in to prop that…

In this tutorial we are going to get you started with react-router-dom using an example React application showing you how to use different concepts such as Link and NavLink for creating links (instead of anchors) in the React way, Switch and exact for enabling exclusive routing and browser routing history.

📦 The final release of React 16 is here!   #javascript #angularjs #100DaysOfCode #reactjs

  • Among the changes are some long-standing feature requests, including fragments, error boundaries, portals, support for custom DOM attributes, improved server-side rendering, and reduced file size.
  • Think of error boundaries like try-catch statements, but for React components.
  • According to Sasha’s synthetic benchmarks, server rendering in React 16 is roughly three times faster than React 15.
  • “When comparing against React 15 with compiled out, there’s about a 2.4x improvement in Node 4, about a 3x performance improvement in Node 6, and a full 3.8x improvement in the new Node 8.4 release.
  • Fiber is responsible for most of the new features in React 16, like error boundaries and fragments.

We’re excited to announce the release of React v16.0! Among the changes are some long-standing feature requests, including fragments, error boundaries, portals, support for custom DOM attributes, improved server-side rendering, and reduced file size.

Writing Server-rendered React Apps with Next.js — SitePoint

Writing Server-rendered #ReactJS Apps with Next.js:  by @sitepointdotcom #JavaScript

  • This gets you all the dependencies you need for starting: – $ npm install next react react-dom –save – – Create a directory for your app, and inside that create a directory called pages.
  • js inside your project with these contents: – export default () = ( – divHello, Next!
  • So, you just have a style component inside your React Component render function: – export default () = ( – div – Hello world – pThese colors are scoped!
  • So, you can write code like this that dynamically loads a React component after initial load: – import dynamic from ‘next/dynamic’ – – const = dynamic( – { – loading: () = pThe component is loading…/p – } – ) – – export default () = – div – Header…
  • Next renders pages on the server, and they can be loaded just like good old rendered web pages when JavaScript is disabled.

  • React Alicante 2017This weekend I have been in Spain to attend React Alicante.
  • It’s the first edition of this conference focused in React and React Native.Glenn Reyes on stage talking about code splitting to improve the performance of our React apps.The conference was 3-day long, one day with workshops introducing React and React Native, and 2 days for talks in a single track.It’s the…
  • It was truly international, with all talks delivered in English (something unusual in Spain) and 250 attendees from 25+ countries.The most impressive is that it was arranged by 2 Spanish expats who form the company Limenius, based in Munich.
  • They managed to prove that it’s possible to arrange a good conference in a well-communicated location like Alicante, with good weather and interesting attractions, while making it affordable (the regular tickets for the talks were 99€).
  • Other topics were forms, CSS in JS, Redux/Mobx, code splitting, GraphQL, and React Native.They covered pretty well the current ecosystem of tools when working with React, and they shared learnings that can be applied to our daily jobs.If you are interested in the specifics of the talks, check this list…
