  • Redux-saga is a Redux middleware to handle side effects, mainly the asynchronous actions which change the state.
  • A saga is a generator function that can run asynchronous actions indefinitely like a thread in the application.
  • On the other hand, Redux-saga uses the generators which can pause, resume, and interact with the asynchronous actions by using generators.
  • Each of the following functions will return a saga effect which is an object containing instructions of what/how the action should be executed by the saga middleware.
  • takeEvery – – Resolve the effect with the result of each time that the action is received.

No Bundle URL Present – Joshua Kuhar – Medium

No Bundle URL Present  #ios #reactnative #reactjs #reactjs

Create amazing 360 and VR content using React #ReactVR #ReactJS

Create amazing 360 and VR content using React



#ReactVR #ReactJS

  • React VR is a framework for the creation of VR applications that run in your web browser.
  • Leveraging web technologies and the existing React ecosystem, React VR aims to simplify the construction of 360 experiences and democratize the creation of VR content.
  • We’ve designed the React VR developer experience to get your first project up and running in only a few minutes.
  • Before installing the developer tools, you’ll need to make sure that you have two prerequisites installed:

    Next, install the React VR CLI – a command-line tool that generates the basic layout of new projects.

  • It’s helpful if you include the version of React VR, Browser, and OS you’re using.

React Native with Apollo — Part 2, Apollo Client – React Native Development – Medium

  • We return the App component we will create next and wrap it in passing in the client as a prop.
  • create a new query using gql that we will use when we create the higher order component
  • gql will be used to create our query.
  • The graphql method will allow us to create a higher order component for providing Apollo data to a component.
  • create a component named President that we will pass to the higher order component along with the query

Here, we will be using the Apollo GraphQL server we created in part 1 to retrieve data from our database and render it in our app.

Develop React Native/Redux Applications like a BOSS with this tool – React Native Development – Medium

  • In the post I’ll show you how to setup the amazing React Native Debugger.
  • global.reduxNativeDevTools(/*options*/) : noop => noop ); const store = createStore(reducer, initialState, enhancer); // If you have other enhancers & middlewares // update the store after creating / changing to allow devTools to use them if (global.reduxNativeDevTools) { global.reduxNativeDevTools.updateStore(store); } return store; }
  • If you’re using Redux to manage your state in React Native apps then you should also be using the React Native Debugger to super charge your development experience.
  • Make sure you have Homebrew installed on your system by executing ‘brew’ in your Terminal.
  • Never miss a story from React Native Development , when you sign up for Medium.

React Native: The Bad Parts

  • Our app worked great with the first 2 ways, but we couldn’t build the apk because React Native clobbers your NODE_ENV environment variable only when you’re actually building the apk.
  • React Native Apps Run In Least 3 Different Environments
  • Each of the ways gives you a very different app, and it’s quite common for code to work as expected when using react-native run-android but fail miserably when you actually ship the apk.
  • To include native extension like, say, a wrapper around the Java version of analytics.js , you need to npm install a package and then make some changes to RN’s Java code.
  • In my several months of React Native dev, I’ve learned the painful lesson that React Native is still at least several years away from being useful for anything but the most trivial of apps .

If you haven’t heard the React Native hype train yet, you will: it’s probably
the only thing that’s noisier than the Caltrain at 6am. However, in my several months of React Native dev,
I’ve learned the painful lesson that React Native is still at least several
years away from being useful for anything but the most trivial of apps. My next stop: progressive web
apps, and if that doesn’t work out, I’m going back to Cordova. Here’s why.

Introducing React Native Ubuntu

Even @Ubuntu has gone all #Native on us! -  #Reactjs #ReactNative #JavaScript

  • We have support for web applications and creating and packaging Cordova applications, both of these enable any web framework to be used in creating great application experiences on the Ubuntu platform.
  • To get started, follow the instructions in README-ubuntu.md and create your first application.
  • React Native is the sister to React.js, you can use the same style and code to create an application that works directly with native components with native levels of performance, but with the ease of and rapid development you would expect.
  • We want to make everyone’s life easier, enable the use of tools that are familiar to web developers and provide an easy path to using them on the Ubuntu platform.
  • Over the next little while there will be blogs posts on everything you need to know about developing a React Native Application for the Ubuntu platform; creating the app, the development process, packaging and releasing to the store.
