Where each one falls short

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

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

Spring Boot

  • Requires Java 17 as the minimum version for Spring Boot 4.1.0, per docs.spring.io/spring-boot/system-requirements.html (Aug 2026); older Java runtimes are not supported
  • Requires Spring Framework 7.0.8 or above and Gradle 8.14+ or Maven 3.6.3+, per Spring's own system requirements page, so older toolchains must be upgraded first
