AuthService

Kind: Class

Source: Frontend/src/app/services/security/auth.service.ts (line 131)

Part of: Frontend

AuthService manages authentication-related state and navigation checks in the frontend. It exposes methods for login, token access, route detection, branch switching, user information persistence, and activation decisions.

Methods

Properties

Where it refuses work

• AuthService stops the work with an early return when !token, in 6 places.
• AuthService stops the work with an early return when !expirationDate, in 2 places.
• AuthService stops the work with an early return when item === undefined || item === null.
• AuthService stops the work with an early return when window.location.href.includes("ogin") || window.location.href.includes("ignin") || window….
• AuthService stops the work with an early return when window.location.href.toLocaleLowerCase().includes("edit") || window.location.href.toLocal….
• AuthService stops the work with an early return when url === 'home' || url === ''.

When something fails

• AuthService handles failure in 5 places: it turns it into a return value in 4, and logs it and continues in 1.

Usage

ts
import { Component } from '@angular/core';
import { AuthService } from './services/security/auth.service';

@Component({
  selector: 'app-account',
  template: `
    <button *ngIf="!isLoggedIn" (click)="login()">Log in</button>
    <button *ngIf="isLoggedIn" (click)="switchBranch()">Switch branch</button>
  `,
})
export class AccountComponent {
  constructor(private readonly authService: AuthService) {}

  get isLoggedIn(): boolean {
    return this.authService.isLoggedIn();
  }

  login(): void {
    this.authService.login();
  }

  switchBranch(): void {
    const branch = this.authService.switchBranch();
    console.log('Selected branch:', branch);
  }
}

AI Coding Instructions

• Keep authentication checks in AuthService rather than duplicating login or token logic in components.
• Call canActivate() from route guard integration points and redirect with routeToLoginPage() when access is denied.
• Check isLoginPage() and isSheetPage() before applying page-specific authentication behavior.
• Read tokens through getToken() instead of accessing authentication state directly.
• Keep saveUserLoggedInInformation() and verify() aligned with the login flow.
