Security scanning for React apps

Codanopy detects a React app the way it detects any JavaScript/Node project — from package.json, lockfiles, and .js/.jsx/.ts/.tsx source — then runs dependency, secret, and pattern analysis against it plus an AI pass that reads across files rather than one component at a time.

Detected as: JavaScript / Node. Codanopy detects and scans at the language level, so React projects get full dependency, secret, and pattern coverage; the notes below name patterns specific to how React apps tend to be structured, not a separate React-aware analyzer.

What to watch for in React

• A backend secret given a VITE_ or REACT_APP_ prefix so the frontend can read it — which inlines it into the public JavaScript bundle at build time
• Protected routes enforced only by a client-side route guard or a hidden button, with no matching check on the API the page calls
• dangerouslySetInnerHTML rendering user- or LLM-supplied content without sanitisation
• Auth tokens kept in localStorage, where any XSS in the app can read and exfiltrate them
