  • Readability in the age of AI-assisted programming
    ESLint - a pluggable and configurable linter tool. - Source: dev.to / 10 days ago
  • The Judgement Pyramid: Reasoning vs Measurement
    Is this reasoning, or measurement? If measurement, push it to a deterministic tool. Sonar, Spotless, Ruff, ESLint, coverage gates, pre-commit hooks, complexity calculators. Write a script if no tool exists. That's how just lint got built, and that's the Unix-philosophy move for agentic coding. Hooks fire on tool calls; CI fires on PRs; pre-commit fires on commit. Pick the cheapest layer that catches the failure... - Source: dev.to / 3 months ago
  • How to Build a Dependency Map of a Legacy Codebase Using AI Tools
    137Foundry provides legacy modernization services that include dependency mapping as a foundational assessment phase. Prettier and ESLint are useful companion tools for enforcing code style consistency as the refactoring proceeds. Node.js and Python.org official documentation are authoritative references for understanding the import and module systems of those runtimes. - Source: dev.to / 4 months ago
  • How to Prepare a Legacy Codebase for AI-Assisted Refactoring
    Prettier and ESLint are useful tools for establishing consistent code style as a baseline before starting structural refactoring - style differences in a diff make behavioral changes harder to spot. OWASP provides useful checklists for security-critical code review that apply directly to the critical path review step. - Source: dev.to / 4 months ago
  • When to Split a React Component (And When You're Over-Engineering)
    Splitting for file length alone, splitting before a pattern appears at least twice, and splitting in ways that produce tightly coupled pairs of components are the patterns most worth avoiding. ESLint with the react-hooks plugin helps catch when extracted hooks still have too many concerns, by flagging dependency arrays that have grown unwieldy. - Source: dev.to / 4 months ago
