Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Express.js

  • Governed by the OpenJS Foundation with no vendor or paid tier, per expressjs.com; as open source software it has no pricing to compare
  • Express.js provides only a thin layer of fundamental routing features by its own description, requiring separate middleware modules for functionality like body parsing, sessions or authentication

MySQL

  • Hot online backup is not in the free Community Server; MySQL Enterprise Backup is a paid Enterprise Edition component
  • Transparent Data Encryption, data masking and de-identification are Enterprise Edition only
  • MySQL Enterprise Firewall, which guards against SQL injection, and MySQL Enterprise Audit are both paid components
  • External authentication against PAM or Windows Active Directory requires MySQL Enterprise Authentication
  • The thread pool ships as MySQL Enterprise Scalability rather than in the community build
