Caching React Native Builds on S3 and R2
Article Summary
Your React Native CI builds are probably slower and more expensive than they need to be. Callstack just shared a practical caching strategy that could change that.
Callstack's latest article tackles a common pain point in React Native CI/CD: slow, costly builds that repeat the same work. They explore using S3 and Cloudflare R2 as caching layers to speed up build times and reduce infrastructure costs.
Key Takeaways
- S3 and R2 can cache React Native build artifacts between CI runs
- Proper caching eliminates redundant compilation and dependency resolution
- Works with existing CI/CD pipelines without major infrastructure changes
Critical Insight
Strategic build caching on S3 or R2 can dramatically reduce React Native CI times and costs by reusing artifacts across builds.
