Dependency and Supply-Chain Security

npm dependencies power React applications, but they also introduce risk: every package you install can be a backdoor. Supply-chain attacks—from typosquatting to stolen credentials to malicious code injection—are now the #1 vector for compromising production builds. The good news is that tools like npm audit, Socket, lockfiles, and Dependabot make it feasible to audit, lock down, and automate security updates across your entire dependency tree.

This series covers the complete toolkit for hardening React's npm supply chain. You will learn how to audit dependencies for known vulnerabilities, distinguish between legitimate packages and typosquats, pin versions with package-lock.json to prevent silent supply-chain mutations, use Socket to detect behavioral anomalies in real time, set up Dependabot for continuous patching, and generate Software Bill of Materials (SBOMs) for compliance and transparency. By the end, you will have a zero-trust dependency workflow that catches attacks before they reach your repo—and keeps running 24/7.
