Sunsetting React Native – Airbnb Engineering & Data Science – Medium

  • This is the fourth in a series of blog posts in which we outline our experience with React Native and what is next for mobile at Airbnb.
  • Although many teams relied on React Native and had planned on using it for the foreseeable future, we were ultimately unable to meet our original goals.
  • Failing to Reach OurGoals – Move Faster – When React Native worked as intended, engineers were able to move at an unparalleled speed.
  • It is not allbad – Although we werent able to achieve our goals with React Native, engineers who used React Native generally had a positive experience.
  • Every company that uses React Native will have an experience that is a unique function of their team composition, existing app, product requirements, and maturity of React Native.

Why You Should Use Simpler-Redux For React-Redux Development

  • Why You Should Use Simpler-Redux For React-Redux Development – Simpler-redux is a new well tested library that simplifies react-redux development, but also greatly reduces react-redux code size, simplifies debugging and improves testing capabilities.
  • After those exclusions and excluding comments, the simpler-redux code required only 52 lines of code whereas the react-redux version required 190 lines of code to do the same thing.
  • That means the simpler-redux implementation is less than 1/3 the code size of react-redux.
  • Moreover, if your project had 20 react-redux components, simpler-redux would require just 1040 lines of code whereas react-redux would need around 3800 lines.
  • So, clone a working side by side implementation of the redux reddit example written in both simpler-redux and react-redux and verify for yourself the tremendous code savings and the simplicity of simpler-redux.

React Native at Airbnb – Airbnb Engineering & Data Science – Medium

  • This is the first in a series of blog posts in which we outline our experience with React Native and what is next for mobile at Airbnb.
  • Placing a Bet on ReactNative – We are continually evaluating new technologies to enable us to improve the experience of using Airbnb for guests and hosts, move quickly, and maintain a great developer experience.
  • Because of this, we saw React Native as an opportunity to open up mobile development to more engineers as well as ship code more quickly by leveraging its cross-platform nature.
  • React Native enabled us to launch Experiences, an entirely new business for Airbnb, as well as dozens of other features from reviews to gift cards.
  • Different teams had a wide range of experiences with React Native.
