# Dependency upgrade

Suitable for front-end dependency upgrades, bug fixes, major version migrations and lockfile risk reviews. Load [references/dependency-upgrade-workflow.md](references/dependency-upgrade-workflow.md) when you need specific processes and checklists.

## Purpose

Reduce disruptive changes, supply chain risks, and CI regressions by upgrading dependencies in a provenance-driven and small-batch verification manner.

## Procedure

1. Establish a baseline of truth: Read package manager, lockfile, Node version, workspace scope, CI commands, and current verification status.
2. Classified upgrade goals: security fixes, patch upgrades, minor version upgrades, major version migrations, framework migrations, build tool migrations, or dependency cleanup.
3. Verify sources: For version-sensitive libraries, read official release notes, migration guide, peer dependency, Node/browser support and deprecation items.
4. Split into smaller batches: Security patches can be processed centrally; large versions, build tools, frameworks and testing tools must be verified in separate batches.
