Five years ago, we announced that React Native (RN) is the future of mobile at Shopify. Today, we are excited to share the progress we've made, lessons learned, and what the future holds.

Instead of using a one-size-fits-all approach to do so, each team chose when and how to migrate their app. This allowed them to continue shipping features while also aligning with our strategy of leveraging RN. What did we learn? React Native apps are fast We care very deeply about performance at Shopify. As our CEO Tobi Lutke says, “not all fast software is great, but all great software is fast”. The biggest question we had while switching to RN and the main reason we didn’t do it sooner was whether we’d be able to achieve our performance goals with it. Before making the decision to switch, we did extensive prototyping which led to promising results. We also saw all the work that Meta
