Release Management

Semantic Versioning Script

// scripts/release.ts
import { execSync } from 'child_process';

async function release(versionType: 'patch' | 'minor' | 'major') {
  // Run tests
  execSync('npm test', { stdio: 'inherit' });
  
  // Bump version
  const newVersion = execSync(`npm version ${versionType}`).toString().trim();
  
  // Generate changelog
  execSync('npx conventional-changelog -p angular -i CHANGELOG.md -s');
  
  // Create git tag
  execSync(`git tag -a ${newVersion} -m "Release ${newVersion}"`);
  
  // Push
  execSync('git push origin main --tags');
  
  console.log(`Released ${newVersion}`);
