npm-migrate
by AlejandroRV
AI-assisted migration and upgrade of npm packages. Handles breaking changes between major versions, deprecation cleanup within minor versions, adopting new APIs and patterns, security-driven upgrades from npm audit, and full dependency replacement (swapping one package for another, e.g. moment → dayjs). Analyzes changelogs, git diffs, and docs, scans your codebase for actual usage, cross-references to find what's affected, generates targeted code fixes or codemods, and verifies with your test suite. Use this skill whenever a user mentions upgrading, migrating, or updating npm packages, dealing with breaking changes, fixing deprecation warnings, replacing a dependency with an alternative, adopting new APIs from a package update, running npm audit fix with code changes, or comparing what changed between package versions. Trigger phrases include: "upgrade axios to v2", "migrate to express 5", "replace moment with dayjs", "fix deprecation warnings", "npm audit says vulnerable", "adopt the new API", "what changed between version X and Y", "swap lodash for es-toolkit", "help me upgrade my dependencies", "clean up deprecated calls".
