Summary from the TLDR Dev newsletter

This dev reduced their Node.js Docker images from over 1GB to under 80MB. They started by replacing heavy base images with slim or Alpine versions. Then, they added a proper .dockerignore file and used multi-stage builds to make sure that only essential production files and compiled artifacts are included in the final container.
