🚀 Quick Start

1. Basic Usage (Standalone)

Inject the service into your component using the modern inject() pattern:

import { Component, inject, OnInit } from '@angular/core';
import { CookieManagerService } from 'ngx-cookie-manager';

@Component({
  selector: 'app-root',
  standalone: true,
  template: `<h1>User: {{ username }}</h1>`
})
export class AppComponent implements OnInit {
  private cookieService = inject(CookieManagerService);
  username = '';

  ngOnInit() {
    // Set a cookie
    this.cookieService.set('username', 'JohnDoe', 7); // Expires in 7 days
    
    // Get a cookie
    this.username = this.cookieService.get('username');
  }
}

2. Advanced Configuration

this.cookieService.set(
  'session_id', 
  'xyz123', 
  { 
    expires: 1,           // 1 day
    path: '/', 
    secure: true, 
    sameSite: 'Strict' 
  }
);

🌐 Server-Side Rendering (SSR)

ngx-cookie-manager uses Angular's DOCUMENT token and PLATFORM_ID to determine the execution context.

• In the Browser: Interacts directly with document.cookie.
• On the Server: Safely returns default values (empty strings/objects) to prevent application crashes during pre-rendering or hydration.
