Instead of caching node_modules (which often corrupts), cache a single .istargz file. Build time drops from 12 minutes to 45 seconds.

An image repack modifies a pre-existing Docker Hub or OCI image into an optimized eStargz format without modifying the application code.

It compares the current package-lock.json with the one inside the existing .tar.gz archive. A well-organized MERN project is critical for long-term

Achieving a highly optimized repack involves multiple pipeline steps: 1. Dependency Pruning and Tree Shaking When the Node
