Faster local dev with build cache providers in Expo (Experimental)
Blog post from Expo
SDK 53 introduces an experimental feature that enhances the speed of npx expo run:[android|ios] by using a remote build cache based on project fingerprints, allowing developers to skip recompiling the same code and share cached builds with their team. By configuring experiments.buildCacheProvider in the app config, the system searches for a matching build on a remote server and downloads it if available, otherwise compiling locally and uploading it for future use. This process, which automatically benefits team members sharing the same cache, is particularly useful for larger applications or frequent branch changes. The feature can be customized with different build cache providers, including the EAS build provider, which compiles locally on a cache miss, and GitHub Releases for hosting custom caches. Currently, the number of cached builds is limited per billing cycle on various plans, but adjustments are anticipated as the feature matures towards a stable release.
