Why Shopify Migrated From React Native

Shopify từng sử dụng React Native cho ứng dụng di động của mình nhưng quyết định quay về phát triển native do hiệu năng không như kỳ vọng. Vấn đề chính nằm ở bộ nhớ chiếm dụng cao đến 86MB khi khởi chạy ứng dụng React Native, trong khi native app chỉ cần khoảng 16MB. Sự chậm trễ khi load màn hình và animation do JavaScript bridge gây ra làm trải nghiệm người dùng kém đi. Shopify đã chuyển hoàn toàn sang native development với Kotlin cho Android và Swift cho iOS, giúp giảm 70% kích thước ứng dụng và cải thiện đáng kể performance.
