How to make reusable component in Angular?

How to make reusable component in Angular?

Hello guys how are you? Welcome back to my blog therichpost.com. Today in this post I will let you know How to make reusable component in Angular?

Guys in this working demo I will reuse button component into my other components in Angular 14.

In thus post, I am using Angular @Input decorator to share data between components.

Working live demo

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

1. Firstly friends we need fresh angular 14 setup and for this we need to run below commands but if you already have angular 14 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, here we need to run below commands into our project terminal to install bootstrap 5 modules and create button component into our angular application:

npm install bootstrap

npm i @popperjs/core

ng g c button

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

<button type="button" class="btn btn-primary" [disabled] = "disabled">Primary</button>

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

import { Component, OnInit, Input } from '@angular/core';

@Component({
  selector: 'app-button',
  templateUrl: './button.component.html',
  styleUrls: ['./button.component.css']
})
export class ButtonComponent implements OnInit {
   
  //decorator to share data between conponents
  @Input() disabled:boolean = true;

  constructor() { }

  ngOnInit(): void {
  }

}

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

<div class="container p-5">
    <app-button [disabled] = 'disabled'></app-button>
</div>

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

import { Component } from '@angular/core';
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'angulardemo';
  
  //variable for button
  disabled:boolean = false;
  
  constructor() { }
  ngOnInit(): void {
  }
}

7. Now we need to add our bootstrap files link inside angular.json file:

"styles": [
              ...
              "node_modules/bootstrap/dist/css/bootstrap.min.css"
          ],
"scripts": [
              ...
               "node_modules/bootstrap/dist/js/bootstrap.min.js"
           ]

Friends in the end must run ng serve command into your terminal to run the angular 14 project.

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

Note: Friends, In this post, I just tell the basic setup and things, you can change the code according to your requirements.

I will appreciate that if you will tell your views for this post. Nothing matters if your views will be good or bad because with your views, I will make my next posts more good and helpful.

Jassa
