React Modernization

React Modernization

Selective Reading Rule

Start with:

• references/senior-master-standard.md
• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

Master React version upgrades, class to hooks migration, concurrent features adoption, and codemods for automated transformation.

Use this skill when

• Upgrading React applications to latest versions
• Migrating class components to functional components with hooks
• Adopting concurrent React features (Suspense, transitions)
• Applying codemods for automated refactoring
• Modernizing state management patterns
• Updating to TypeScript
• Improving performance with React 18+ features

Do not use this skill when

• The task is unrelated to react modernization
• You need a different domain or tool outside this scope

Instructions

• Clarify goals, constraints, and required inputs.
• Apply relevant best practices and validate outcomes.
• Provide actionable steps and verification.
• If detailed examples are required, open resources/implementation-playbook.md.

Resources

• resources/implementation-playbook.md for detailed patterns and examples.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
