React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.

Server Rendering with React and React Router

Server Rendering with React and React Router, by @tylermcginnis  #reactjs #react

  • Now that we get the big picture, let’s work on creating the foundation for what will become a server rendered React Router app.
  • Here’s what the React docs have to say about this – – When you’re just rendering a component with no data, it’s not difficult to have the server rendered and client rendered content be identical – as we saw when we just rendered .
  • You need to make sure that the component is rendered with the same data (or props) on both the client and server.
  • The idea is when a GET request is made to our server, instead of calling immediately, we fetch the popular repositories first and then call it after giving our React app the data.
  • The client because it obviously needs to know which components to render as the user navigates around our app and the server because it needs to know which data to fetch when the user requests a specific path.

Give React Native a(nother) try + ReactNative Navigation

  • React Native is no different from other – – tools in this regard, so I want to present a few reasons why you might want to give – – React Native a(nother) try now, just over two and a half years since its initial release.
  • # Native Navigation with React Navigation – – – – You start using React Native.
  • You can either use a library that wraps the native navigation APIs for the platform or a re-implementation of those APIs using the same React Native primitives (View, Text, Animated, etc) that you use throughout your app.
  • React Navigation (https://reactnavigation.org/) is a “JavaScript-based” navigation solution and React Native Navigation is a “native” navigation library.
  • I lead the React Navigation along with the creator of the project, Eric Vicenti.

Brent Vatne (expo.io, ReactNative) and Eric Vicenti (ReactNative @Facebook) are in town delivering training…# Reasons to give React Native a(nother) tryWhen a highly hyped new tool is released, many

Building A Sticky Sidebar In React

Building A Sticky Sidebar In React  #reactjs #webdev #javascript

  • In this three part live coding series, we will build a basic 8-2 column layout and add a sticky sidebar to our app.
  • In the process, we will learn about how we can create dummy paragraphs programmatically and leverage several useful functions from Lodash, Boostrap and React-Sticky component.
  • We start our app by using the Create React App boilerplate.
  • We will use several ES6 features, so if you need a refresher, check out these tutorials: – – If you enjoyed this tutorial, make sure to subscribe to our Youtube Channel and follow us on Twitter @pentacodevids for latest updates!

How and Why to Bind a Callback Function in React Components

How and Why to Bind a Callback Function in #reactjs Components  #javascript

  • If you ask yourself, why you even have to bind callback functions and when you actually have to do this, this article is for you: Today we’re going to learn about binding the  keyword in React components.
  • Avoid binding by using the public class fields syntax, or bind your callbacks inside the constructor.
  • Another way to bind  is to do so in your parent component’s constructor by calling for your callback function: – – That’s it!
  • Instead of binding the callback function in your constructor, you can do so while passing it through a prop: – – Note: Whenever your component is re-rendered, returns a new function and passes it down your component tree.
  • Instead of using the public class field syntax, you could directly pass an arrow function down your props: – – Note: Like in the previous example, this creates a new callback each time your component is re-rendered and may cause unnecessary re-rendering of your component tree.

Why do we need to bind ‘this’? What’s the best way to bind a callback function in React components? Read about the why and how in this article and never worry about binding callbacks again!

A React Navbar Component by Dan on CodePen

A simple, responsive #Navbar using #ReactJS:  @CodePen #coding

  • I’m going to give it a name of NavComponent because that just makes way too much sense, and inside the render function, toss in an empty (for now) set of tags to wrap around everything else that will go in there: – – And underneath all that I’m going to…
  • This will give my a “hamburger” icon (courtesy of Font Awesome) for smaller screens that need a drop down menu.
  • Since our drop-down menu is contained in the “narrowLinks” className, we’re going to target that in our function: – – And then tell our function to toggle the drop-down based on its current CSS display value: – – And to make the new function work, we need to give our…
  • I obviously don’t want to see both sets of links all the time, and since we’re using mobile-first design, we’re going to set our “navWide” links to hidden: – – And we’re also going to stick our hamburger icon and drop-down links on the left side of the screen, just…
  • And finally a media query to switch between our mobile drop-down menu and our larger screen mode with just a row of our links: – – For a working example, click here.

Design Spin Builds a React Website with Cosmic JS – Hacker Noon

  • If this was a WordPress website the language we would be using on the server side would be PHP, but we would still be using JavaScript on the client side for any browser trickery such as the image sliders mentioned.
  • When you visit this website, the first page is delivered from the server then further page changes are handled client side.
  • Lighthouse is available within the Google Chrome browsers development tools, allowing you to quickly audit any of your web pages for Progressive Web Apps, Performance, Best Practices and Accessibility.
  • “I hope in the future that this new website will convince clients to avoid WordPress and use the fantastic Cosmic JS API to build apps and manage content.”
  • Carson Gibbons is the Co-Founder CMO of Cosmic JS, an API-first Cloud-based Content Management Platform that decouples content from code, allowing devs to build slick apps and websites in any programming language they want.
