Angular 6 Flash Messages

 Angular provides us so many default features and Flash Message is one of them.

Here are the steps, you need to follow for Angular Flash Messages:


1. First, you need to run below command into your terminal to add Angular Flash Message Package into your Angular 6 App:
npm install angular2-flash-messages --save


2. After add below code into your app.module.ts file:
import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { FlashMessagesModule } from 'angular2-flash-messages';

  declarations: [AppComponent],
  imports: [
  entryComponents: [AppComponent],
  providers: [],
  bootstrap: [AppComponent]
export class AppModule { }


3. After this, you need to add below code into app.component.ts file:
import {Component} from '@angular/core';
import { FlashMessagesService } from 'angular2-flash-messages';
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
export class AppComponent {
constructor(private flashMessage: FlashMessagesService) { }
  showFlash() {
        // 1st parameter is a flash message text
        // 2nd parameter is optional. You can pass object with options.
        this.flashMessage.show('Welcome To TheRichPost.com', { cssClass: 'alert-success', timeout: 2000 });


4. After it, you need to add below code into your app.component.html file:
<div class="jumbotron text-center">
  <h1>Angular Flash Messages
<button type="button" (click) = "showFlash()" class="btn btn-primary">Show Flash Messages</button>
