next-upgrade

Automated Next.js version upgrades with official codemods and migration guide integration. Upgrade the current project to the latest Next.js version following official migration guides. 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: 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: Common transforms: Update dependencies : Upgrade Next.js and peer dependencies together: Review breaking changes : Check the upgrade guide for manual changes needed: Update TypeScript types (if applicable): Test the upgrade : - Detects current Next.js version from package.json and fetches version-specific upgrade documentation from official guides - Runs Next.js codemods automatically to handle breaking changes like async Request APIs, geo/IP property migrations, and dynamic import transformations - Handles incremental upgrades for major version jumps (e.g., 13 → 14 → 15) and updates peer dependencies (React, React DOM, TypeScript types) in a single step - Validates upgrades by running build and dev commands to catch errors before completion -...
