Upgrading Next.js safely involves applying codemods that follow official migration guides to automate dependency updates and type changes. This skill coordinates transforms and validates the build workflow to reduce manual effort across incremental major version jumps.

Codemods are automated code transformation tools that apply official migration guide transforms to update code patterns during a Next.js migration. They systematically modify source files to match newer framework APIs, reducing manual upgrade effort and risk.

Yes, this approach supports upgrading Next.js projects using either npm or pnpm. The automation parses your package.json, applies codemods, and installs the latest next, react, and react-dom dependencies based on your detected package manager.

Handling incremental Next.js major version upgrades requires following official migration pathways and applying codemods in a safe sequence. The process detects your current version, applies transforms, bumps dependencies, and validates the build after each major jump.

Yes, the upgrade process updates TypeScript types for React. After applying codemods and installing the latest next, react, and react-dom packages, the automation updates TypeScript types and validates your development workflow to ensure compatibility.

If your Next.js build fails after a major version upgrade, you should validate your development workflow and check for compatibility issues. The automation includes build validation steps to ensure codemod transforms and dependency updates are properly applied and compatible.
