Upgrade Next.js

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

Instructions

Detect current version: Read package.json to 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:

npx @next/codemod@latest

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:

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):

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

Test the upgrade:

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