About this pageAI generated

This page describes a CLI tool called node-weight that reveals the real cost of packages in node_modules. Following the CanisterWorm malware outbreak in March 2026, the author recognized that developers lack visibility into their dependencies. The tool displays three critical pieces of information: package size, security vulnerabilities, and last update date. Abandoned packages with high download counts pose significant supply chain attack risks. Node-weight requires zero installation and can be run with a single command, producing a table showing all installed packages with their metrics, including size in KB, security status, and days since last update.
