Your Node.js Docker Image Is Probably Over 1GB. Here’s How to Get It Under 210MB

A bloated Node.js Docker image isn't just messy , it slows deploys, inflates registry costs, and widens your attack surface. Five targeted fixes: switching to Alpine, ordering layers for cache reuse, adding a .dockerignore, using multi-stage builds, and dropping root. This cuts a 1.58GB image down to 209MB, an 87% reduction that compounds across every node, pipeline run, and security scan.
