Shopify has decided to build all new mobile apps using React Native, a framework for building native mobile apps using JavaScript. The company made this decision after experimenting with React Native and finding it to be a good fit for their needs. Shopify believes that React Native will allow them to bring the power of JavaScript and the web to mobile, adopt a reactive programming model, and consolidate their iOS and Android development onto a single stack. The company plans to continue hiring native engineers and contributing to the React Native community.
