React Native at Airbnb: The Technology – Airbnb Engineering & Data Science – Medium

  • We have Android, iOS, React Native, and web versions of every component.
  • We opted to rewrite components instead of wrapping native ones because it was more reliable to make platform-appropriate APIs individually for each platform and reduced the maintenance overhead for Android and iOS engineers who may not know how to properly test changes in React Native.
  • Iteration Speed – While developing in React Native, we were able to reliably use hot reloading to test our changes on Android and iOS in just a second or two.
  • Backed byNative – Because everything in React Native can be bridged by native code, we were ultimately able to build many things we werent sure were possible at the beginning such as: – Shared element transitions: We built a SharedElement component that is backed by native shared element code on…
  • JS/React OpenSource – Because React Native truly runs React and javascript, we were able to leverage the extremely vast array of javascript projects such as redux, reselect, jest, etc.

A tale of Webpack 4 and how to finally configure it in the right way

  • scripts: { dev: webpack –mode development, build: webpack –mode production}If you paid close attention, you have checked your main.js file and saw it was not minified.
  • babelrcpaste there: – {presets: [ env ]}We have two options for configuring babel-loader: – using a configuration file webpack.config.js – using –module-bind in your npm scripts – – You can technically do a lot with new flags webpack introduces but I would prefer webpack.config.js for simplicity reasons.
  • Configuration file – Although webpack advertises itself as a zero-configuration platform, it mostly applies to general defaults such as entry and output.
  • scripts: { – build: webpack –mode production, – dev: webpack –mode development – },Now when we run npm run build it should output us a nice minified.
  • js file: – import world);In webpack create a new rule for css files: – // webpack v4 – const path = require(‘path’); – const ExtractTextPlugin = = { – entry: { main: ‘.
