Before a build job can begin compiling your project, all project dependencies need to be available on disk. The longer it takes to acquire the dependencies, the more you need to wait for your build to complete — so caching dependencies is an important part of speeding up your builds.
We're actively working on improving caching and other aspects of the build process in order to make builds reliably fast.
It is not yet possible to save and restore
node_modules between builds.
EAS Build runs a Maven cache server that can speed up downloading Android dependencies for your build jobs.
There is no caching done for CocoaPods dependencies yet.
