In this recorded webinar, Mike Grabowski (CTO at Callstack) and Michał Pierzchała (Principal Engineer at Callstack) demonstrate how to dramatically reduce React Native build times using Callstack's open-source React Native Enterprise Framework (RNEF). Discover how Expensify slashed their debug build times from 40 minutes to just 2 minutes without changing CI providers. Learn about smart fingerprinting techniques that can eliminate up to 90% of unnecessary native builds, why conventional caching approaches often fail, and how to implement effective solutions. The presentation includes a live demonstration, actual GitHub Actions pipelines, and detailed cost comparisons to provide a practical understanding of native build caching that works seamlessly across local development, CI workflows, and end-to-end tests. The webinar covers how RNEF enhances modularity, flexibility, and speed for large-scale React Native projects, plus strategies for incrementally adopting the framework in existing Community CLI projects. Perfect for developers facing CI bottlenecks or managing growing React Native codebases who want to accelerate delivery without increasing costs.
