Upgrade Next.js
Upgrade the current project to the latest Next.js version following official migration guides.
Instructions
- Detect current version: Read
package.jsonto identify the current Next.js version and related dependencies (React, React DOM, etc.)
- Fetch the latest upgrade guide: Use WebFetch to get the official upgrade documentation:
- Codemods: https://nextjs.org/docs/app/guides/upgrading/codemods
- Version-specific guides (adjust version as needed):
- https://nextjs.org/docs/app/guides/upgrading/version-16
- https://nextjs.org/docs/app/guides/upgrading/version-15
- https://nextjs.org/docs/app/guides/upgrading/version-14
- Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15).
- Run codemods first: Next.js provides codemods to automate breaking changes:
bash
npx @next/codemod@latest <transform> <path>Common transforms:
next-async-request-api- Updates async Request APIs (v15)next-request-geo-ip- Migrates geo/ip properties (v15)next-dynamic-access-named-export- Transforms dynamic imports (v15)
- Update dependencies: Upgrade Next.js and peer dependencies together:
bash
npm install next@latest react@latest react-dom@latest- Review breaking changes: Check the upgrade guide for manual changes needed:
- API changes (e.g., async params in v15)
- Configuration changes in
next.config.js - Deprecated features being removed
- Update TypeScript types (if applicable):
bash
npm install @types/react@latest @types/react-dom@latest- Test the upgrade:
