# Dependency Upgrade
Master major dependency version upgrades, compatibility analysis, staged upgrade strategies, and comprehensive testing approaches.
## When to Use This Skill
- Upgrading major framework versions
- Updating security-vulnerable dependencies
- Modernizing legacy dependencies
- Resolving dependency conflicts
- Planning incremental upgrade paths
- Testing compatibility matrices
- Automating dependency updates
## Semantic Versioning Review
```
MAJOR.MINOR.PATCH (e.g., 2.3.1)
MAJOR: Breaking changes
MINOR: New features, backward compatible
PATCH: Bug fixes, backward compatible
^2.3.1 = >=2.3.1 <3.0.0 (minor updates)
~2.3.1 = >=2.3.1 <2.4.0 (patch updates)
2.3.1 = exact version
```
## Dependency Analysis
### Audit Dependencies
```bash
# npm
npm outdated
npm audit
npm audit fix
# yarn
yarn outdated
yarn audit
# Check for major updates
npx npm-check-updates
npx npm-check-updates -u # Update package.json
```
### Analyze Dependency Tree
```bash
# See why a package is installed
npm ls package-name
yarn why package-name
# Find duplicate packages
npm dedupe
yarn dedupe
# Visualize dependencies
npx madge --image graph.png src/
```
## Compatibility Matrix
```javascript
// compatibility-matrix.js
const compatibilityMatrix = {
'react': {
'16.x': {
'react-dom': '^16.0.0',
'react-router-dom': '^5.0.0',
'@testing-library/react': '^11.0.0'
},
'17.x': {
'react-dom': '^17.0.0',
'react-router-dom': '^5.0.0 || ^6.0.0',
