The Future of State in React

The Future of #State in #reactjs   #javascript #developers

  • React’s new Context API will be the go-to solution for sharing state simply™️.
  • In this post, I’ll describe Context by creating a simple theme-switching component: – – Since Context won’t be live until React 16.3, I’ll be using the polyfill.
  • Creating a Context instance is as simple as calling a function with a default value .
  • Context’s has less emphasis on global state than Redux and can be used to as little or as large a scale that you’d want: just like MobX.
  • In the following snippet, I set up a React Component that manages the state that our Provider will pass to those willing to consume it: – – Consumers must be descendants of its context’s Provider for it to access the value it wants.

The days of relying on state-management libraries for non-local state are coming to a close. You wont need Redux anymore. Not even MobX. React’s new Context API will be the go-to solution for sharing state simply™️.

My experience with React 16

  • If you have a React 15.5 app which doesn’t use deprecated features and doesn’t throw errors, then React 16 just works!
  • One of my favorite things about React is that it gives me access to a great library of open-source components.
  • And thanks to the stability of React’s API, I haven’t needed to upgrade many of these components… until now.
  • In previous versions of React, throwing exceptions within event handlers would have unpredictable results.
  • While React’s API hasn’t changed much, it has an entirely new engine under the hood called React Fiber.

Now I don’t want to waste your time with another “What is React 16?”; the official blog is already very informative. But what I can give you is the story of my experience this week, when I upgraded a large project to React 16.

Easily Styling React Apps In JavaScript

Easily Styling React Apps In JavaScript

☞ 

#reactjs #javascript

  • While many developers still use CSS to style their React apps, writing styles in JavaScript has become an increasingly popular practice as it gives all of the conveniences of CSS preprocessors without the need to learn a new language.
  • Most CSS-in-JS libraries involve creating a JavaScript object of styles.
  • As an example, this is what a style object looks like using my preferred library, Aphrodite.
  • For example, when styling placeholder text, I use a function that returns an object of styles:

    One of biggest advantages of writing styles in JavaScript is that classNames are scoped to each component by default.

  • There are lots of helpful libraries for creating JavaScript styles.

React, Firebase & Me – Crystal Tate – Medium

React, Firebase & Me  #api #react #javascript #firebase #womenintech #reactjs

  • For my quarter 1 project, I decided to make a web app using React for my frontend and Firebase for my backend — two technologies I knew nothing about.
  • Galvanize gave me this confidence, by the way.The other students in my class were wrestling with code and working towards their project goals.
  • I had yet to commit one line of code, while the other students were approaching their MVPs.I didn’t want to abandon my goal of using React for this project; but I wondered who I thought I was.
  • I’d essentially learned to make delicious code bread, yet I was attempting to make code puff pastry for my project.
  • I was able to make even more progress on my project at school.

Life as a student at Galvanize is incredibly rewarding and truly challenging. Each day we’re tasked with much more than the day before, and somehow we keep moving along. Tuesday was totally defeating…

Deploying React pages to Share

Deploying @reactjs pages to #alfresco Share by @_DaveDraper

  • We need to eject in order to gain access to the start.js script that is edited to allow us to add custom HTTP proxy middleware .
  • If you want your users to access this new page with the context of Share then it makes sense to include the standard header and footer.
  • Once the server has restarted you’ll be able to login to Share and then you will be able to access your page at /share/page/react .
  • Content tagged with alfresco share
  • In the blog post I’m going to step through the process of creating a page using React and deploying it into Share.

Introduction I’ve previously experimented with developing Alfresco clients using a number of different application frameworks. In this blog post I’m going

Employee Directory: Sample Application with React Native and Node.js

Employee Directory: Sample app with #ReactNative and #NodeJS

  • In React Native , you render your components using React Native components like and which are wrappers around native components.
  • React Native is a framework for building native mobile applications using JavaScript.
  • Trivia application built with React (hosted live )
  • The source code for the React Native application is available in this GitHub repository.
  • The REST service implementation (employee-service-rest.js) uses fetch to access Node.js-based REST services hosted on Heroku .

Over the past few years, I’ve built many versions of the Employee Directory application as a way to explore new languages and frameworks. In this post I’ll share a version of the Employee Directory sample app built with React Native.
