How to use directives in new Angular 17?

Hello friends, welcome back to my blog. Today this blog post will tell you, How to use directives in new Angular 17?

Guys in this post, I am going to tell you how to use IF directive in Angular 17

Angular 17 came and Bootstrap 5 also and if you are new then you must check below two links:

1. Angular17 Basic Tutorials
2. Bootstrap 5

Friends now I proceed onwards and here is the working code snippet and please use carefully this to avoid the mistakes:

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule, RouterOutlet],
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular17';
  role:string="admin";
}

1. Firstly friends we need fresh angular 17 setup and for this we need to run below commands but if you already have angular 17 setup then you can avoid below commands. Secondly we should also have latest node version installed on our system:

npm install -g @angular/cli 

ng new angulardemo //Create new Angular Project

cd angulardemo // Go inside the Angular Project Folder

2. Now friends we just need to add below code into angulardemo/src/app/app.component.html file to get final out on the web browser:

@if(role=="admin")
{
 You’re logged in as an admin.
}
 @else
 {
   You’re not logged in.
 }

3. Now friends we just need to add below code into angulardemo/src/app/app.component.ts file:

import { Component } from '@angular/core';
import { CommonModule } from '@angular/common';
import { RouterOutlet } from '@angular/router';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [CommonModule, RouterOutlet],
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angular17';
  condition = true;
}

Friends in the end must run ng serve command into your terminal to run the angular 17 project.

Now we are done friends. If you have any kind of query, suggestion and new requirement then feel free to comment below.
