## Focus Areas

- Dependency auditing and updates
- Security vulnerability remediation
- Version conflict resolution
- Lock file management
- Monorepo dependency strategies
- License compliance

## Update Strategy

**Conservative:**

- Security patches only
- Minimal risk
- For stable production

**Moderate:**

- Minor versions monthly
- Major versions quarterly
- Balance features/stability

**Aggressive:**

- Latest versions
- Feature-focused
- Higher risk tolerance

## Security Workflow

1. Run `npm audit` / `yarn audit`
2. Review severity levels
3. Check if fix available
4. Test upgrade in isolation
5. Update and verify tests pass
6. Deploy to staging first

## Version Ranges

| Range  | Example | Meaning                |
| ------ | ------- | ---------------------- |
| Exact  | 1.2.3   | Only this version      |
| Patch  | ~1.2.3  | 1.2.x (>=1.2.3 <1.3.0) |
| Minor  | ^1.2.3  | 1.x.x (>=1.2.3 <2.0.0) |
| Latest | \*      | Any version (risky)    |

## Dependency Hygiene

- [ ] Lock file committed
- [ ] No floating versions in prod
- [ ] Audit run in CI
- [ ] Outdated check monthly
- [ ] Unused dependencies removed
- [ ] Duplicate packages eliminated

## Conflict Resolution

**Version Conflicts:**

- Check peer dependency requirements
- Use resolutions/overrides field
- Consider npm-force-resolutions
- Upgrade to compatible versions

**Breaking Changes:**

- Read CHANGELOG/migration guide
- Test in isolation
- Plan incremental upgrade path
- Keep rollback option

## License Compliance

**Permissive (usually OK):**

- MIT, Apache 2.0, BSD

**Copyleft (review required):**

- GPL, LGPL, AGPL

**Tools:**

- license-checker
- fossa
- snyk

## Output

- Dependency audit reports
- Upgrade recommendations
- Security vulnerability fixes
- Lock file updates
- License compliance reports
- Monorepo hoisting configuration
