Understanding higher-order components

  • Why use HOC: Promote reuse of logic across React components.
  • How to use HOC: The core structure of a HOC is a function that takes a component and returns a new component.
  • HOC are pure functions with no side-effects because the component passed in, is wrapped in a new component.
  • The HOC looks like this: – – State now has a property to inject data from the API fetch into the wrapped component via the prop.
  • React Redux connect has a different function signature of a function returning a function which accepts one argument (ie, ‘component’) to create a HOC.

Building Native Mobile Apps with React Native

Building Native Mobile Apps with React Native |

  • It’s been tough for developers to create native apps in different OS platforms.
  • Moreover, developing the native apps for different platforms requires skill sets and experience pertinent to the OS platform.
  • As a result, React Native is making progress by providing Real Native experience for different OS platforms.
  • The beauty of React Native is that it allows developers to build native apps using JavaScript and React.Its main theme lies on utilizing the power of React in native platforms.
  • The most useful features of React Native are the capability to write source code only in React Native, and the ability to compile it on various OS platforms.

React Native is providing Real Native experience for different OS platforms. It allows developers to build native apps using JavaScript and React.

Using Electrode to Improve React Server Side Render Performance By Up To 70%

  • js application platform that powers walmart.com with several goals in mind, including ease of use, re-usability of components across applications and, most importantly, performance.We use server side rendering for almost all of our applications for two reasons:Improved performance for the customerBetter for SEOIn our tests, however, we found that React’s renderToString() takes quite a while to execute — and since renderToString() is synchronous, the server is blocked while it runs.
  • Every server side render executes renderToString() to build the HTML that the application server will be sending to the browser.To solve this problem, we created two Electrode modules: Above the Fold Render (ATF) and Server Side Render Profiling and Caching (SSR Caching).
  • The average renderToString()call with this configuration took 153.80 ms.Electrode default, though, Electrode comes with renderWithIds:false, which gives us a renderToString() time of 124.80 ms. Not bad — Electrode’s default configuration has already improved render time by 19%!
  • That drops our renderToString() time all the way to 36.56 ms — an astounding 71% improvement from the default Electrode configuration, and a 76% improvement from our original, unoptimized test.
  • That means a 70% improvement won’t mean 90 ms, but 180 ms saved.Special Thanks:To Arunesh Joshi, Dmitry Yesin, and the home page team who have implemented the Electrode modules and are using them on the home page in production.To Caoyang Shi, for helping to gather data and ensuring we’re getting the right numbers!More Information:Check out Joel Chen’s post on ReactJS SSR Profiling and Caching or Arpan Nanavati’s post on Building React.js at Enterprise Scale.Check out my post about the release of Electrode, the customer-facing platform that powers Walmart.com.The Electrode website: www.electrode.io

Embracing React  #ui #react #software #reactjs #cloud #reactjs

  • This allows the UI (which is a huge cost in any build) to be re-useable — a huge business benefit when building cloud software.We had been using Backbone as our main UI framework and had found that too much logic hid itself inside our models.
  • There was no clear delineation between where the model ended and the logic began.Beautiful design can be implemented in any framework (or without one at all!)
  • This is due to the main logic being removed from the grid itself and only the common state changes, such as a loading state, remaining triggered by the main logic.In 2015 we were starting a few new projects from scratch, so we decided to use React as the framework for the UI.
  • The solution was to build these common components to be re-usable from the ground up — so they could be dropped into any app seamlessly.One component we’ve used multiple times is a card dashboard (shown above) — where we separate bite-size information chunks into cards that can then expand into a larger picture.
  • React has been an ideal framework for developing these cards as separate modules that have no dependencies on other cards or the underlying dashboard layout.Another useful outcome of React is that our designer is able to communicate in components as building blocks.

React is a JavaScript library for building UI and it promises many things. But the main one that appealed to us was the idea that state and logic could be easily removed from the UI code and placed…

Using Native Modules in React Native and Building an App from Scratch

Next stop on the #ReactNative Cookbook book tour, React Native Boston Meetup!

  • How about if we have an existing native app that we want to seamlessly integrate React Native into?
  • This talk will cover how we can use JavaScript and a little bit of native code to unlock the hidden power of React Native.
  • Stan has specialized in JavaScript framework development for over five years and recently co-authored the “React Native Cookbook” (Packt Press) released in December 2016.
  • While we won’t be able to cover building the entire app during the talk, you should leave with a better understanding on how to get started, how to think about and build components and screens, or simply an appreciation for how React Native enables us to build great mobile apps.
  • Chris is a Founding Partner at Echobind, a web and mobile agency specializing Ember, React Native, Rails and Elixir/Phoenix.

*NOTE: Different venue this month!*
This month, we have talks by Stan Bershadskiy from Modus Create and Chris Ball from Echobind!

Scripting Native App with React Native – Supreet Totagi – Medium

Scripting native app with React Native:  #frontend #ReactJS #JavaScript

  • Even though native development takes longer, there are many reasons why we can produce better experience on mobile than on web.
  • React Native apps can access platform features like the phone camera, or the user’s location.
  • With all the advantages of native development, what we really want is user experience of native mobile apps combined with developer experience we have when building on the web.
  • Scripting Native App with React Native
  • If we use JavaScript to build native mobile apps, we would probably make this stack work across multiple platforms combined with great developer experience that comes in building apps for the Web.
