How do you describe various dependencies in angular application?

The dependencies section of package.json with in an angular application can be divided as follow,

1. Angular packages: Angular core and optional modules; their package names begin @angular/.
2. Support packages: Third-party libraries that must be present for Angular apps to run.
3. Polyfill packages: Polyfills plug gaps in a browser's JavaScript implementation.

Practical Code Example

// package.json dependencies:
{
  "dependencies": {
    "@angular/core": "^19.0.0",
    "rxjs": "^7.8.0"
  },
  "devDependencies": {
    "@angular/cli": "^19.0.0",
    "typescript": "~5.5.0"
  }
}
