How does this skill help with breaking changes?

It provides specific patterns for identifying breaking changes via changelogs and automates the refactoring process using codemods and custom migration scripts.

Can I use this for both npm and yarn projects?

Yes, the skill includes comprehensive commands and best practices tailored for both npm and yarn, including workspace management and lock file synchronization.

Does it support automated dependency updates?

Yes, it includes configuration templates for Renovate and Dependabot to help teams automate minor and patch updates while flagging major version jumps for review.

What is the recommended testing approach during an upgrade?

The skill advocates for a layered approach starting with unit tests, followed by integration and E2E tests, and finally visual regression to ensure no UI breakage occurred.

デプロイメントとDevOps

Manages major dependency version upgrades through systematic compatibility analysis, staged rollouts, and automated testing strategies.

概要

This skill provides a comprehensive framework for navigating the complexities of major software updates and framework migrations. It facilitates every stage of the upgrade lifecycle, from initial auditing and semantic versioning analysis to executing staged rollouts and applying automated codemods. By integrating compatibility matrices and multi-layered testing (unit, integration, and E2E), the skill minimizes the risks associated with breaking changes and peer dependency conflicts in modern web applications.
