Update Dependencies: $ARGUMENTS

Updates npm packages to their latest versions with automated testing and validation in an isolated worktree.

Arguments

• Specific packages: jest @types/jest
• All packages: .
• Glob patterns: @testing-library/* jest*

Process

1. Create Isolated Worktree

WORKTREE_NAME="npm-update-$(date +%Y%m%d-%H%M%S)"
WORKTREE_PATH="../$WORKTREE_NAME"
git worktree add "$WORKTREE_PATH" -b "$WORKTREE_NAME"
cd "$WORKTREE_PATH"

2. Identify Packages

• Parse $ARGUMENTS to determine packages
• For globs, expand against package.json dependencies
• For ., update all packages

3. Check and Update Versions

# Check latest version
npm view <package> version

# Prefer LTS when available
npm view <package> dist-tags

# Update packages
npm install <package>@latest

4. Run Security Audit

npm audit
npm audit fix

5. Validate Updates

Run in order, continue on failure to collect all errors:

npm run build
npm run lint
npm test

6. Handle Results

On success:

• Create commit with version changes
• Use AskUserQuestion to prompt:
  • "Yes, merge and clean up (Recommended)"
  • "No, I'll review first"
  • "Discard changes"

On failure:

• Categorize errors (build/lint/test/audit)
• Provide specific remediation steps
• Offer options: isolate problem, revert specific updates, or abandon

7. Cleanup

git worktree remove "$WORKTREE_PATH"
git branch -D "$WORKTREE_NAME"

Error Categories

Edge Cases

• No package.json: Error with clear message
• Not a git repo: Error - worktree requires git
• Package not found: Suggest checking package name
• Glob matches nothing: Warn and list available packages
