    "build": "tsc"
  },
  "dependencies": {},
  "devDependencies": {
    "typescript": "^5.5.3"
  },
  "private": true
}

The old tsconfig.json

    "target": "es2016",
    "module": "commonjs",
    "esModuleInterop": true,

    "strict": true,
    "skipLibCheck": true,
    "outDir": "dist"
  },
  "include": ["src"]
