ESLint

  • Slow performance on large codebases compared to newer tools like Oxlint and Biome
  • Complexity in configuration from scratch, particularly for TypeScript support
  • Limited built-in TypeScript support, requiring separate parsers and coordination with new TypeScript features

HTMX

  • Best suited for server-rendered architectures, not pure client-side SPAs
  • Limited client-side state management capabilities compared to frameworks
  • Smaller ecosystem with fewer third-party libraries and tools
  • Learning curve for developers from JavaScript framework backgrounds
