next-upgrade

You can automate a Next.js upgrade by executing official codemods and updating peer dependencies like React and TypeScript types simultaneously to resolve breaking changes across the project.

Next.js codemods are official transformation scripts that automatically update code patterns for new major versions. You need them during migrations to handle breaking changes like async request API transforms.

Yes, this Next.js migration tool synchronizes dependency updates by ensuring Next.js, React, and TypeScript types are upgraded to compatible versions simultaneously to prevent build-time failures.

The best way to handle Next.js breaking changes in a large codebase is applying automated transformation scripts to update code patterns and synchronizing all peer dependencies automatically.

Yes, the migration process requires file system access to modify package.json and execute npx commands for running the official Next.js transformation scripts.

Manually upgrading Next.js without codemods is complex and error-prone because you must individually resolve breaking changes and manually verify peer dependency compatibility across the entire codebase.
