10 Essential npm Security Practices Every Developer Should Follow

In the past year, npm has experienced frequent security issues, making it essential for both front‑end and back‑end developers to consider npm security. Open‑source code auditing is a crucial part of application security, and npm package safety should be a top priority, especially as even the npm CLI itself can be vulnerable.

Snyk, a Node.js security provider, has compiled a memo of ten npm security best practices for open‑source maintainers and developers.

Never publish secret keys to npm.

Use a lockfile to lock dependency versions.

Reduce attack surface by running npm with --ignore‑scripts.

Assess the health of your npm project.

Check for vulnerabilities in dependent open‑source projects.

Employ a local npm proxy.

Disclose security vulnerabilities responsibly.

Enable two‑factor authentication.

Use npm author tokens.

Understand module naming conventions and protect against typosquatting attacks.

For detailed explanations, refer to the original article; the memo can also be downloaded and printed for a constant security reminder at your workspace.
