Following multi-version security updates from the Node.js project, teams running server-side JavaScript must update their runtimes and audit their npm ecosystems. Here is a practical walkthrough for maintaining production runtime security.

Updating Node.js via Version Managers and Docker

For environments managed via nvm or fnm, execute nvm install --lts && nvm use --lts. In containerized deployments, update your Dockerfile base image references (such as node:22-alpine) to the latest official image digests and rebuild your images.

Performing Supply Chain Audits with npm audit

Run npm audit across all application repositories to detect vulnerable transitives. Apply non-breaking updates via npm audit fix, and thoroughly review changelogs for any packages requiring major version upgrades.
