In this Ionic 5/4 article, we’ll learn how to show local notifications or push messages in Ionic Angular application. These Notifications can be sent from triggers within the app using Cordova and Native plugins with number of configurations available.

Some of the applications may have some operations running on the device without any need for network connections. In that case, we may want to show some type on notifications like reminders, alerts of some notifications other then push messages. Such type of notifications which are pushed by the locally installed app in the device is local notifications. 

In Ionic applications it’s possible to show local notifications with a variety of flexible options like ID, custom sound, text, title, LED color customizations, etc.

Here we will create a new Ionic Application with a blank template to demonstrate the different types of local notifications with example.

Let’s get started!


Supported Platforms

  • Android
  • iOS
  • Windows


Update Ionic CLI

First, make sure you have the latest version on Ionic CLI installed on your system. Run following CLI command to update Ionic CLI to the latest version

$ npm install -g @ionic/cli


Create an Ionic Application

To demonstrate Ionic local notifications we will create a new Ionic application. If you already have a running application just use that. Run following CLI command to create a new Ionic application with a blank template.

# Create app
$ ionic start ionic-local-notification-app blank --type=angular

# Change directory
$ cd ionic-local-notification-app

# Open code in Visual Studio Code
$ code .

Install Cordova and Native Local Notification Plugin

After creating and moving to the app folder in CLI we will install Cordova and Ionic native plugin for Local Notifications to work in the application.

Run following CLI commands to install the native plugin.

$ ionic cordova plugin add cordova-plugin-local-notification
$ npm install @ionic-native/local-notifications

Import Local Notification Plugin in App Module

To use local notification we need to import local notification then add in providers array. Open the app.module.ts file, then make the following changes.

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppComponent } from './app.component';
import { AppRoutingModule } from './app-routing.module';

import { LocalNotifications } from '@ionic-native/local-notifications/ngx';

  declarations: [AppComponent],
  entryComponents: [],
  imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule],
  providers: [
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  bootstrap: [AppComponent]
export class AppModule {}

Use Local Notification in Home Component

To create a Local notification we first need to import it in component then call schedule method with options.

Add the following buttons in the file.

  <ion-button (click)="single_notification()">
    Single Notification
  <ion-button (click)="multi_notification()">
    Multi Notifcations
  <ion-button (click)="delayed_notification()">
    Delayed Notification

then add three types of example methods with different options in file

import { Component } from '@angular/core';

import { LocalNotifications } from '@ionic-native/local-notifications/ngx';

  selector: 'app-home',
  templateUrl: '',
  styleUrls: [''],
export class HomePage {

  constructor(private localNotifications: LocalNotifications) { }

  single_notification() {
    // Schedule a single notification
      id: 1,
      text: 'Single ILocalNotification',
      sound: 'file://sound.mp3',
      data: { secret: 'key_data' }

  multi_notification() {
    // Schedule multiple notifications
      id: 1,
      text: 'Multi ILocalNotification 1',
      sound: 'file://sound.mp3',
      data: { secret: 'key_data' }
    }, {
      id: 2,
      title: 'Local ILocalNotification Example',
      text: 'Multi ILocalNotification 2',
      icon: ''

  delayed_notification() {
    // Schedule delayed notification
      text: 'Delayed ILocalNotification',
      trigger: { at: new Date(new Date().getTime() + 3600) },
      led: 'FF0000',
      sound: null


If next notification is having the same id, it will replace the previous. The schedule() method is called with configuration option properties to trigger a local notification.

So by using a Local Notification native plugin, we can easily show customized notification from an application itself on the device. you can check more options and examples here



We discussed how to easily implement the local notification in the Ionic application scheduled from the application itself which can be triggered from outside to inside the application using Cordova and native plugins.

Hope you enjoyed this tutorial, thanks for reading!
