  • Well, React’s fast-paced performance and easy learning played a crucial role in highlighting and well-liked javascript among other several of available Javascript.
  • Some stunning features expect its typical attributes has enabled React to win the race rapidly and steadily.
  • Below in the first graph, you can see the popularity raised within the last two years which is acceptable due to the tremendous support of the React with the application development which we have already discussed.
  • Now coming to the second graph as you can see the another Javascript liked and most preferred by the developers i.e AngularJS compared with the React.

Understanding Navigation In React Native

  • Navigation has to do with the nav bars, tab bars and side menu drawers in your mobile application.
  • You should check out the React Native documentation on how to get started with React Native and React Navigation.
  • We can use this to relate to the StackNavigator which simply means adding screens on top of each other like a stack.
  • A code snippet of ScreenOne:

    One of the major difference between this navigator and the rest is and which opens and closes the drawer.

  • If you have to use React Native Navigation libraries, you should check out this list of amazing libraries for React Native.

I’ll be taking you through React Navigation. Navigation has to do with the nav bars, tab bars and side menu drawers in your mobile application.
At the end of the tutorial, you should have a pretty…

  • Accept Payments with Apple Pay and using the Payment Request API.
  • Note that you’ll need to run it from a browser with Payment Request support.
  • Before you can start accepting payments with Apple Pay, there are a few steps you’ll need to go through:

    Apple has a documentation on how to do both of these in their Configuring your Environment guide.

  • You can dismiss the Payment Request at any point by calling the method.
  • If you’re equiped to Apple Pay payments on your server, all you have to do is send the Payment Response’s and to your server.

React Behavioral Wrapper Components – Ian Carlson – Medium

React Behavioral Wrapper Components  #ui #react #javascript #reactjs

  • But because of how flexible React is you can create wrapper components that add behavior to the children being passed through.
  • This is more applicable when using Redux since not all the backend requests are made within the same component, like a session container for example.Here’s a example of creating an opacity animation component that adds the animation to any child component.
  • This is based on the example in the React documentation using the CSS transition group extension to apply fade-in, fade-out animations based on the lifecycle of the child component(s).
  • The former is actual animation time and the latter is how long temporary classes will stay in existence.Here’s an example of how to use the OpacityAnimation:You can also pass an array of children as well, but it’s important to carefully manage the key properties on each child — even for just one child.
  • For example, a tooltip component would display the children as is, but then attach event handlers to display the tooltip on the right conditions.

Another great thing about React is how easy it is to add behavior to components through composition. Typically new people only think of composition in terms of layout. But because of how flexible…

Using RxJS with React.js: Part 3 — Dispatching events from Component

Using RxJS with React.js: Part 3 - Dispatching events from Component

  • Using RxJS with React.js: Part 3 — Dispatching events from ComponentThis is the third part of the series.Illustration of unidirectional flow between Subject and ComponentUnidirectional cycleEarlier we saw an example of HoC streaming props to the base component.
  • Let’s now look at ways how we can dispatch events from inside the base component, update some value, and the updated value will then be streamed back to the component completing one unidirectional cycle.We can take the example of a form input field.
  • To keep things simple, let’s say BehaviorSubject is a kind of Subject, that can already start with an initial value.import { BehaviorSubject } from ‘rxjs’;const subject$ = new = console.log(x)); // prints `foo` right awayThe base Component with form inputLet’s say this is our base component:import React from ‘react’const MyComponent = React.createClass({ render() { const { value, handleChange } = this.props; return ( div input type=”text” value={value} onChange={e = handleChange(e.target.value)} / pCurrent value: {value}/p /div ); }});From the base component, we are accessing the props value and handleChange.
  • First one is a stream of the input value, and the latter for handling the change.import { BehaviorSubject, Observable } from ‘rxjs’;const formInput$ = new BehaviorSubject(‘foo’); // with initial valueconst handlers$ = Observable.of({ handleChange: value = formInput$.
  • scan(function (props, emitted) { return { …props, …emitted }; });Observing the base ComponentNow that we have the props$ observable ready, we can integrate it with our base complement easily using the observe function from FrintJS:import { observe } from ‘frint-react’;const ObservedRoot = observe(function () { return props$;})(MyComponent);Now you can stream the props, including both the input value and the change handler from your HoC, and also trigger changes in the Subject from your Component’s events.Live demoVisit this example in JSBin.

Earlier we saw an example of HoC streaming props to the base component. Let’s now look at ways how we can dispatch events from inside the base component, update some value, and the updated value will…
