Safely upgrading Next.js involves orchestration: reading package.json to detect current versions, fetching official codemods, applying them to fix breaking changes, and validating builds. This Skill automates that entire process stepwise.

Codemods are automated code transformation tools used during a Next.js migration to fix breaking changes. This Skill fetches and runs official codemods to update your codebase automatically, reducing manual refactoring when jumping between major versions.

Upgrading Next.js across multiple major versions is supported through incremental migrations. The Skill reads package.json, determines the current version, and guides stepwise migrations to ensure React and related tooling compatibility.

The Next.js upgrade process updates React, React-DOM peers, and TypeScript types. It reads package.json to determine current versions and updates dependencies to ensure compatibility with the target Next.js release.

The best way to automate Next.js dependency updates is using a tool that orchestrates package.json updates, runs codemods, and validates builds. This Skill fetches official guides, updates dependencies, and runs tests to verify the migration succeeded.
