Build a simple video streaming app with OpenTok & React Native

  • This time we came up with an experiment to build simple mobile application that allow user to live stream their mobile camera using OpenTok and React Native.
  • OpenTok is video platform tool from TokBox community to easily integrate high-quality video,audio streaming with your web or mobile apps.
  • Once you ready with your OpenTok account registration process, you can create a new project for your react native mobile app.
  • Let’s see the steps required to integrate an OpenTok session within React Native app for both Android and iOS – – This plugin is build by integrating native ’s with Javascript.
  • Subscriber component is allow user to join with specified live stream using Session id and Subscriber token like below, – – So the result, we ended up with simple cross-platform mobile app that perform live streaming.

Challenges with React native app development is growing day by day. We are always ready to accept those challenges and make our development process enjoyable.

Getting started with React Native

  • React Native helps you to build apps that no one would ever tell you that you did not use a custom native language such as JAVA or Swift or Objective C. React Native gives you that extra feel.
  • Create React Native App is the easiest way to start building a new React Native application.
  • It allows you to start a project without installing or configuring any tools to build native code – no Xcode or Android Studio installation required.
  • Do a change of directory to the location where you installed the React Native App.
  • NOTE: Create React Native App makes it really easy to run your React Native app on a physical device without setting up a development environment.

Introducing React Native Android Fragment – In The Hudl – Medium

  • So today we are announcing our first open source project for React Native at Hudl.React Native Android Fragment: Native Android Fragment does exactly what its name implies.
  • It helps to facilitate the development of a React Native application, for a pre-existing Android application that relies on the framework’s Fragment class.
  • It can be downloaded via jitpack and its versioning will attempt to always follow that of React Native’s major.minor versions.Our Android app originated around 2013 when Fragments were the Android standard and we’ve stuck with them ever since.
  • For anyone else that has tried to use React Native, you may also realize that support for Fragments is non-existent.
  • We hope this library, although small, may help others to get started quickly into the React Native ecosystem.

React Native Performance

#ReactNative performance and some tricks & tools to optimize your React Native application:

  • Every character typed in the Native component involves the physical event, transforms it in letter or action, and then transmits it by the bridge to the JS component.
  • In all of the transactions of data between JS and Native, the Bridge always intervenes so that the data is included in both parts.
  • The Animated library has been created to improve the performance of the animations, and its objective is to lighten the use of the bridge by sending predictions of the data to the native before starting the animation.
  • Thankfully, the Bridge isn’t the only one at fault, and there are many other ways to optimize a React Native application.Therefore, here is an exhaustive list of why and/or how you can optimize your application:

    The React Native “tooling” is not yet very developed, but a great part of the toolset is that itis coming from the application.

  • The performance of a React Native application is very important.

Getting Started with React Native and Flow – React Native Training – Medium

Getting Started with React Native and Flow 📱👌 #javascript #react #reactnative #flowtype

  • Using the Flow server For a large project, you probably only want Flow to recheck files incrementally when they change.
  • To get started, we first need to make sure we either have flow set up in our project at node_modules/bin/flow (as we have already done above) or installed globally.
  • To stop the server, we can run node_modules/.bin/flow stop to stop the server.
  • In our project, we start the server by running node_modules/.bin/flow , which we’ve saved as an npm script npm run flow .

Flow allows us to easily add static type checking to our JavaScript. Flow will help you prevent bugs and allow for better code documentation among other things. A lot of the React Native…
