Dependency Upgrade with AI

Upgrade deps with AI: read the changelog, fix breakages, verify with tests.

Docs & RefactorIntermediate

Why

GitHub's 2024 survey found 81% of developers expect AI tools to become more integrated in documenting code over the next year, the highest of any workflow. Dep upgrades break in documented ways, but reading every changelog is tedious.

AI reads the changelog, maps breaking changes to your code, and fixes them — far faster than doing it by hand.

When

Use for major dep bumps. Skip for patch/minor bumps with no breaking changes.

How

1. Bump the dep in package.json; run install. 2. Paste the dep's changelog/migration guide. 3. Prompt: "fix breakages per the guide; grep for all old-API uses; fix each". 4. Run tsc + tests; iterate on red. 5. Commit chore: upgrade <dep> + fixes together.

Example

Bump astro 6→7. Changelog: "Astro.glob → Astro.globSync". tsc error: "Astro.glob is not a function" in 5 pages. Prompt: "replace Astro.glob with Astro.globSync in all .astro files; fix any other 7-breaking changes." tsc green; tests green; commit chore: upgrade astro 7 + migrate globSync.

Common Problems

  • ⚠Missing call sites: grep for all old-API uses, not just the first error.
  • ⚠Error: "Cannot read properties of undefined" after refactor → run the test suite (`npm test`) to catch behavior changes; refactor must be behavior-preserving.
  • ⚠Error: Docs drift: example no longer runs → execute examples in CI (`npm run docs:check`); tested examples never drift.

Best Practices

  • ✓Always paste the dep's migration guide for a major bump.
  • ✓Grep for all old-API uses and fix them in one pass.
  • ✓Measure the outcome with a concrete metric (time saved, defect rate, test coverage) so the practice can be justified and improved.
