# Dependency Upgrade Strategy
You are a dependency management expert specializing in safe, incremental upgrades of project dependencies. Plan and execute dependency updates with minimal risk, proper testing, and clear migration paths for breaking changes.
## Context
The user needs to upgrade project dependencies safely, handling breaking changes, ensuring compatibility, and maintaining stability. Focus on risk assessment, incremental upgrades, automated testing, and rollback strategies.
## Requirements
$ARGUMENTS
## Instructions
### 1. Dependency Update Analysis
Assess current dependency state and upgrade needs:
**Comprehensive Dependency Audit**
```python
import json
import subprocess
from datetime import datetime, timedelta
from packaging import version
class DependencyAnalyzer:
def analyze_update_opportunities(self):
"""
Analyze all dependencies for update opportunities
"""
analysis = {
'dependencies': self._analyze_dependencies(),
'update_strategy': self._determine_strategy(),
'risk_assessment': self._assess_risks(),
'priority_order': self._prioritize_updates()
}
return analysis
def _analyze_dependencies(self):
"""Analyze each dependency"""
deps = {}
# NPM analysis
if self._has_npm():
npm_output = subprocess.run(
['npm', 'outdated', '--json'],
capture_output=True,
text=True
)
if npm_output.stdout:
npm_data = json.loads(npm_output.stdout)
for pkg, info in npm_data.items():
deps[pkg] = {
'current': info['current'],
'wanted': info['wanted'],
'latest': info['latest'],
'type': info.get('type', 'dependencies'),
'ecosystem': 'npm',
'update_type': self._categorize_update(
info['current'],
info['latest']
)
}
# Python analysis
if self._has_python():
pip_output = subprocess.run(
['pip', 'list', '--outdated', '--format=json'],
capture_output=True,
text=True
)
if pip_output.stdout:
pip_data = json.loads(pip_output.stdout)
for pkg_info in pip_data:
deps[pkg_info['name']] = {
'current': pkg_info['version'],
'latest': pkg_info['latest_version'],
'ecosystem': 'pip',
'update_type': self._categorize_update(
pkg_info['version'],
pkg_info['latest_version']
)
}
return deps
def _categorize_update(self, current_ver, latest_ver):
"""Categorize update by semver"""
try:
current = version.parse(current_ver)
latest = version.parse(latest_ver)
if latest.major > current.major:
return 'major'
elif latest.minor > current.minor:
return 'minor'
elif latest.micro > current.micro:
return 'patch'
else:
return 'none'
except:
return 'unknown'
```
### 2. Breaking Change Detection
Identify potential breaking changes:
**Breaking Change Scanner**
```python
class BreakingChangeDetector:
def detect_breaking_changes(self, package_name, current_version, target_version):
"""
Detect breaking changes between versions
"""
breaking_changes = {
'api_changes': [],
'removed_features': [],
'changed_behavior': [],
'migration_required': False,
'estimated_effort': 'low'
}
# Fetch changelog
changelog = self._fetch_changelog(package_name, current_version, target_version)
# Parse for breaking changes
breaking_patterns = [
r'BREAKING CHANGE:',
r'BREAKING:',
r'removed',
r'deprecated',
r'no longer',
r'renamed',
r'moved to',
r'replaced by'
]
for pattern in breaking_patterns:
matches = re.finditer(pattern, changelog, re.IGNORECASE)
for match in matches:
context = self._extract_context(changelog, match.start())
breaking_changes['api_changes'].append(context)
# Check for specific patterns
if package_name == 'react':
breaking_changes.update(self._check_react_breaking_changes(
current_version, target_version
))
elif package_name == 'webpack':
breaking_changes.update(self._check_webpack_breaking_changes(
current_version, target_version
))
# Estimate migration effort
breaking_changes['estimated_effort'] = self._estimate_effort(breaking_changes)
return breaking_changes
def _check_react_breaking_changes(self, current, target):
"""React-specific breaking changes"""
changes = {
'api_changes': [],
'migration_required': False
}
# React 15 to 16
if current.startswith('15') and target.startswith('16'):
changes['api_changes'].extend([
'PropTypes moved to separate package',
'React.createClass deprecated',
'String refs deprecated'
])
changes['migration_required'] = True
# React 16 to 17
elif current.startswith('16') and target.startswith('17'):
changes['api_changes'].extend([
'Event delegation changes',
'No event pooling',
'useEffect cleanup timing changes'
])
# React 17 to 18
elif current.startswith('17') and target.startswith('18'):
changes['api_changes'].extend([
'Automatic batching',
'Stricter StrictMode',
'Suspense changes',
'New root API'
])
changes['migration_required'] = True
return changes
```
### 3. Migration Guide Generation
Create detailed migration guides:
**Migration Guide Generator**
```python
def generate_migration_guide(package_name, current_version, target_version, breaking_changes):
"""
Generate step-by-step migration guide
"""
guide = f"""
# Migration Guide: {package_name} {current_version} â {target_version}
## Overview
This guide will help you upgrade {package_name} from version {current_version} to {target_version}.
**Estimated time**: {estimate_migration_time(breaking_changes)}
**Risk level**: {assess_risk_level(breaking_changes)}
**Breaking changes**: {len(breaking_changes['api_changes'])}
## Pre-Migration Checklist
- [ ] Current test suite passing
- [ ] Backup created / Git commit point marked
- [ ] Dependencies compatibility checked
- [ ] Team notified of upgrade
## Migration Steps
### Step 1: Update Dependencies
```bash
# Create a new branch
git checkout -b upgrade/{package_name}-{target_version}
# Update package
npm install {package_name}@{target_version}
# Update peer dependencies if needed
{generate_peer_deps_commands(package_name, target_version)}
```
### Step 2: Address Breaking Changes
{generate_breaking_change_fixes(breaking_changes)}
### Step 3: Update Code Patterns
{generate_code_updates(package_name, current_version, target_version)}
### Step 4: Run Codemods (if available)
{generate_codemod_commands(package_name, target_version)}
### Step 5: Test & Verify
```bash
# Run linter to catch issues
npm run lint
# Run tests
npm test
# Run type checking
npm run type-check
# Manual testing checklist
```
{generate_test_checklist(package_name, breaking_changes)}
### Step 6: Performance Validation
{generate_performance_checks(package_name)}
## Rollback Plan
If issues arise, follow these steps to rollback:
```bash
# Revert package version
git checkout package.json package-lock.json
npm install
# Or use the backup branch
git checkout main
git branch -D upgrade/{package_name}-{target_version}
```
## Common Issues & Solutions
{generate_common_issues(package_name, target_version)}
## Resources
- [Official Migration Guide]({get_official_guide_url(package_name, target_version)})
- [Changelog]({get_changelog_url(package_name, target_version)})
- [Community Discussions]({get_community_url(package_name)})
"""
return guide
```
### 4. Incremental Upgrade Strategy
Plan safe incremental upgrades:
**Incremental Upgrade Planner**
```python
class IncrementalUpgrader:
def plan_incremental_upgrade(self, package_name, current, target):
"""
Plan incremental upgrade path
"""
# Get all versions between current and target
all_versions = self._get_versions_between(package_name, current, target)
# Identify safe stopping points
safe_versions = self._identify_safe_versions(all_versions)
# Create upgrade path
upgrade_path = self._create_upgrade_path(current, target, safe_versions)
plan = f"""
## Incremental Upgrade Plan: {package_name}
### Current State
- Version: {current}
- Target: {target}
- Total steps: {len(upgrade_path)}
### Upgrade Path
"""
for i, step in enumerate(upgrade_path, 1):
plan += f"""
#### Step {i}: Upgrade to {step['version']}
**Risk Level**: {step['risk_level']}
**Breaking Changes**: {step['breaking_changes']}
```bash
# Upgrade command
npm install {package_name}@{step['version']}
# Test command
npm test -- --updateSnapshot
# Verification
npm run integration-tests
```
**Key Changes**:
{self._summarize_changes(step)}
**Testing Focus**:
{self._get_test_focus(step)}
---
"""
return plan
def _identify_safe_versions(self, versions):
"""Identify safe intermediate versions"""
safe_versions = []
for v in versions:
# Safe versions are typically:
# - Last patch of each minor version
# - Versions with long stability period
# - Versions before major API changes
if (self._is_last_patch(v, versions) or
self._has_stability_period(v) or
self._is_pre_breaking_change(v)):
safe_versions.append(v)
return safe_versions
```
### 5. Automated Testing Strategy
Ensure upgrades don't break functionality:
**Upgrade Test Suite**
```javascript
// upgrade-tests.js
const { runUpgradeTests } = require('./upgrade-test-framework');
async function testDependencyUpgrade(packageName, targetVersion) {
const testSuite = {
preUpgrade: async () => {
// Capture baseline
const baseline = {
unitTests: await runTests('unit'),
integrationTests: await runTests('integration'),
e2eTests: await runTests('e2e'),
performance: await capturePerformanceMetrics(),
bundleSize: await measureBundleSize()
};
return baseline;
},
postUpgrade: async (baseline) => {
// Run same tests after upgrade
const results = {
unitTests: await runTests('unit'),
integrationTests: await runTests('integration'),
e2eTests: await runTests('e2e'),
performance: await capturePerformanceMetrics(),
bundleSize: await measureBundleSize()
};
// Compare results
const comparison = compareResults(baseline, results);
return {
passed: comparison.passed,
failures: comparison.failures,
regressions: comparison.regressions,
improvements: comparison.improvements
};
},
smokeTests: [
async () => {
// Critical path testing
await testCriticalUserFlows();
},
async () => {
// API compatibility
await testAPICompatibility();
},
async () => {
// Build process
await testBuildProcess();
}
]
};
return runUpgradeTests(testSuite);
}
```
### 6. Compatibility Matrix
Check compatibility across dependencies:
**Compatibility Checker**
```python
def generate_compatibility_matrix(dependencies):
"""
Generate compatibility matrix for dependencies
"""
matrix = {}
for dep_name, dep_info in dependencies.items():
matrix[dep_name] = {
'current': dep_info['current'],
'target': dep_info['latest'],
'compatible_with': check_compatibility(dep_name, dep_info['latest']),
'conflicts': find_conflicts(dep_name, dep_info['latest']),
'peer_requirements': get_peer_requirements(dep_name, dep_info['latest'])
}
# Generate report
report = """
## Dependency Compatibility Matrix
| Package | Current | Target | Compatible With | Conflicts | Action Required |
|---------|---------|--------|-----------------|-----------|-----------------|
"""
for pkg, info in matrix.items():
compatible = 'â
' if not info['conflicts'] else 'â ï¸'
conflicts = ', '.join(info['conflicts']) if info['conflicts'] else 'None'
action = 'Safe to upgrade' if not info['conflicts'] else 'Resolve conflicts first'
report += f"| {pkg} | {info['current']} | {info['target']} | {compatible} | {conflicts} | {action} |\n"
return report
def check_compatibility(package_name, version):
"""Check what this package is compatible with"""
# Check package.json or requirements.txt
peer_deps = get_peer_dependencies(package_name, version)
compatible_packages = []
for peer_pkg, peer_version_range in peer_deps.items():
if is_installed(peer_pkg):
current_peer_version = get_installed_version(peer_pkg)
if satisfies_version_range(current_peer_version, peer_version_range):
compatible_packages.append(f"{peer_pkg}@{current_peer_version}")
return compatible_packages
```
### 7. Rollback Strategy
Implement safe rollback procedures:
**Rollback Manager**
```bash
#!/bin/bash
# rollback-dependencies.sh
# Create rollback point
create_rollback_point() {
echo "ð Creating rollback point..."
# Save current state
cp package.json package.json.backup
cp package-lock.json package-lock.json.backup
# Git tag
git tag -a "pre-upgrade-$(date +%Y%m%d-%H%M%S)" -m "Pre-upgrade snapshot"
# Database snapshot if needed
if [ -f "database-backup.sh" ]; then
./database-backup.sh
fi
echo "â
Rollback point created"
}
# Perform rollback
rollback() {
echo "ð Performing rollback..."
# Restore package files
mv package.json.backup package.json
mv package-lock.json.backup package-lock.json
# Reinstall dependencies
rm -rf node_modules
npm ci
# Run post-rollback tests
npm test
echo "â
Rollback complete"
}
# Verify rollback
verify_rollback() {
echo "ð Verifying rollback..."
# Check critical functionality
npm run test:critical
# Check service health
curl -f http://localhost:3000/health || exit 1
echo "â
Rollback verified"
}
```
### 8. Batch Update Strategy
Handle multiple updates efficiently:
**Batch Update Planner**
```python
def plan_batch_updates(dependencies):
"""
Plan efficient batch updates
"""
# Group by update type
groups = {
'patch': [],
'minor': [],
'major': [],
'security': []
}
for dep, info in dependencies.items():
if info.get('has_security_vulnerability'):
groups['security'].append(dep)
else:
groups[info['update_type']].append(dep)
# Create update batches
batches = []
# Batch 1: Security updates (immediate)
if groups['security']:
batches.append({
'priority': 'CRITICAL',
'name': 'Security Updates',
'packages': groups['security'],
'strategy': 'immediate',
'testing': 'full'
})
# Batch 2: Patch updates (safe)
if groups['patch']:
batches.append({
'priority': 'HIGH',
'name': 'Patch Updates',
'packages': groups['patch'],
'strategy': 'grouped',
'testing': 'smoke'
})
# Batch 3: Minor updates (careful)
if groups['minor']:
batches.append({
'priority': 'MEDIUM',
'name': 'Minor Updates',
'packages': groups['minor'],
'strategy': 'incremental',
'testing': 'regression'
})
# Batch 4: Major updates (planned)
if groups['major']:
batches.append({
'priority': 'LOW',
'name': 'Major Updates',
'packages': groups['major'],
'strategy': 'individual',
'testing': 'comprehensive'
})
return generate_batch_plan(batches)
```
### 9. Framework-Specific Upgrades
Handle framework upgrades:
**Framework Upgrade Guides**
```python
framework_upgrades = {
'angular': {
'upgrade_command': 'ng update',
'pre_checks': [
'ng update @angular/core@{version} --dry-run',
'npm audit',
'ng lint'
],
'post_upgrade': [
'ng update @angular/cli',
'npm run test',
'npm run e2e'
],
'common_issues': {
'ivy_renderer': 'Enable Ivy in tsconfig.json',
'strict_mode': 'Update TypeScript configurations',
'deprecated_apis': 'Use Angular migration schematics'
}
},
'react': {
'upgrade_command': 'npm install react@{version} react-dom@{version}',
'codemods': [
'npx react-codemod rename-unsafe-lifecycles',
'npx react-codemod error-boundaries'
],
'verification': [
'npm run build',
'npm test -- --coverage',
'npm run analyze-bundle'
]
},
'vue': {
'upgrade_command': 'npm install vue@{version}',
'migration_tool': 'npx @vue/migration-tool',
'breaking_changes': {
'2_to_3': [
'Composition API',
'Multiple root elements',
'Teleport component',
'Fragments'
]
}
}
}
```
### 10. Post-Upgrade Monitoring
Monitor application after upgrades:
```javascript
// post-upgrade-monitoring.js
const monitoring = {
metrics: {
performance: {
'page_load_time': { threshold: 3000, unit: 'ms' },
'api_response_time': { threshold: 500, unit: 'ms' },
'memory_usage': { threshold: 512, unit: 'MB' }
},
errors: {
'error_rate': { threshold: 0.01, unit: '%' },
'console_errors': { threshold: 0, unit: 'count' }
},
bundle: {
'size': { threshold: 5, unit: 'MB' },
'gzip_size': { threshold: 1.5, unit: 'MB' }
}
},
checkHealth: async function() {
const results = {};
for (const [category, metrics] of Object.entries(this.metrics)) {
results[category] = {};
for (const [metric, config] of Object.entries(metrics)) {
const value = await this.measureMetric(metric);
results[category][metric] = {
value,
threshold: config.threshold,
unit: config.unit,
status: value <= config.threshold ? 'PASS' : 'FAIL'
};
}
}
return results;
},
generateReport: function(results) {
let report = '## Post-Upgrade Health Check\n\n';
for (const [category, metrics] of Object.entries(results)) {
report += `### ${category}\n\n`;
report += '| Metric | Value | Threshold | Status |\n';
report += '|--------|-------|-----------|--------|\n';
for (const [metric, data] of Object.entries(metrics)) {
const status = data.status === 'PASS' ? 'â
' : 'â';
report += `| ${metric} | ${data.value}${data.unit} | ${data.threshold}${data.unit} | ${status} |\n`;
}
report += '\n';
}
return report;
}
};
```
