Upgrade Next.js

Upgrade the current project to the latest Next.js version following official migration guides.

Instructions

  1. Detect current version: Read package.json to identify the current Next.js version and related dependencies (React, React DOM, etc.)
  1. 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

  1. Determine upgrade path: Based on current version, identify which migration steps apply. For major version jumps, upgrade incrementally (e.g., 13 → 14 → 15).
  1. 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)

  1. Update dependencies: Upgrade Next.js and peer dependencies together:

``bash npm install next@latest react@latest react-dom@latest ``

  1. 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

  1. Update TypeScript types (if applicable):

``bash npm install @types/react@latest @types/react-dom@latest ``

  1. Test the upgrade:

- Run npm run build to check for build errors - Run npm run dev and test key functionality
