Standards, Specs & Security References for React Native
For production code in React Native, always verify against canonical specifications and security guidance — not just tutorials. Common runtime / language-version compatibility issues are addressed by:
Always cite the spec, not paraphrases:
- • W3C Standards (HTML/CSS)
- • ECMA-262 (JavaScript spec)
- • IETF RFCs (HTTP, JSON, base64, etc)
- • MDN Web Docs — practical reference
Avoid common vulnerabilities:
- • OWASP Top 10 — web security
- • OWASP Cheat Sheet Series
- • NIST SP 800 Series — security publications
- • MITRE CWE — Common Weakness Enumeration
Verify dependencies + audit:
- • npm Registry + `npm audit`
- • GitHub Security Advisories
- • NIST NVD (CVE Database)
- • Snyk Vulnerability DB
Modern toolchain references:
- • GitHub — Open Source Maintenance
- • Docker Documentation
- • Kubernetes Docs
- • Always pin versions in production lockfiles
