Understanding State and Props in React – Hacker Noon

Understanding State and Props in React @RuairidhWM  #JavaScript #Reactjs #WebDev

  • Understanding State and Props in ReactI’ve been playing around with React and Redux recently and thought I would start writing articles on concepts which I’ve had to wrap my head around.So unless you’ve been living in a cave for the past few years, you’ll know that React is an awesome front-end library developed by the good folks at Facebook to make life easier for developers.It’s different to Angular or other frameworks as it is purely front-end (though see the comments below for a great clarification on this).
  • With that said, it’s extremely powerful.One of the concepts I struggled to understand during my learning more about React was the interaction between State and Props.
  • If you’re at all familiar with React then you should know that props flow downwards from the parent component.There is also the case that you can have default props so that props are set even if a parent component doesn’t pass props down.This is why people refer to React as having uni-directional data flow.
  • What happens when a component receives data from someone other than the parent?
  • This is super cool because that means React takes care of the hard work and is blazingly fast.As a little example of state, here is a snippet from a search bar (worth checking out this course if you want to learn more about React)Class SearchBar extends Component { constructor(props) { super(props);this.state = { term: ” }; }render() { return ( div className=”search-bar” input value={this.state.term} onChange={event = / /div ); }onInputChange(term) { this.setState({term}); }}SUMMARYProps and State do similar things but are used in different ways.

react-native-aws-cognito

React Native module for authentication with #AWS Cognito.

  • Motivation to work on this module (and so, best use case) was having a secure, simple and cheap user management system that can access AWS IoT devices.
  • It supports Enhanced (Simplified) Authflow as described on are some limitations in this module:

    Sample code for retrieving signed url and using it to connect with AWS IoT using MQTT over Websocket:

A gentle Introduction to Higher Order Components

  • I want to pick out one use case, the conditional rendering with higher order components, to give you two outcomes from this article as a reader.
  • First, it should teach you about higher order components with the use case of conditional rendering.
  • Keep in mind, that altering the look of a component with a higher order component, specifically in the context of conditional rendering, is only one of several use cases to use HOCs.
  • In order to teach higher order components, the article focuses on the use case of conditional rendering.
  • Now you could use the higher order component but with a function that determines the conditional rendering.

Higher order components, or known under the abbreviation HOCs, are often a hard to grasp pattern in React. The article gives you an introduction to HOCs, how to use them elegantly in the case of conditional rendering and how to abstract them…

Develop React Native #iOS apps on Linux:  #ReactJS #JavaScript

  • Develop React Native iOS apps on LinuxYes, you need a Mac to do any kind of iOS development but that doesn’t mean that you have to write the code in the Mac.
  • You can test this by starting any web server on your dev machine, binding it to that port and trying to reach http://DEV_MACHINE_IP:8585 with a web browser in your Mac.
  • So, I did: I fired up the packager in my dev box with react-native start –host 0.0.0.0 –port 8585 (setting the host to 0.0.0.0 is vital, because otherwise your server will only bind to localhost and won’t be accessible from your Mac).
  • I couldn’t find a setting to tell React Native to poll the packager service in a different host:port pair, so I figured that if I wanted it to access the server running in my dev machine, I had to do a TCP tunnel, which is actually quite easy to set up.
  • You’re all set!Make some changes to your React Native code in your dev machine, then hit Cmd+R in your Mac to see the changes.

Yes, you need a Mac to do any kind of iOS development but that doesn’t mean that you have to write the code in the Mac. You can actually write your code in whatever OS/editor combo you prefer and use…

Adding Users to the Node.js / React.js Neo4j Movie App

Adding Users to the #Nodejs / #Reactjs Neo4j Movie App


via @thesilverlogic

  • Once a user has logged in and navigated to a page that displays movies, the user can select a star rating for the movie or remove the rating of a movie he or she has already rated.
  • When a user visits their own profile, the user will see movie recommendations.
  • These users will be able to log in and out, rate movies, and receive movie recommendations.
  • Before a User can rate a Movie , the the user has to exist – someone has to sign up for an account.
  • Users with established tastes may be interested in finding movies with similar characteristics as his or her highly-rated movies, while not necessarily caring about whether another user has or hasn’t already rated the movie.

Learn how to add users and movie recommendation engine to the Neo4j Movie App Template using Node.js and React.js in addition to the Cypher query language.
