Creating Mobile Apps using Ionic Framework and ABP Framework


In this article, we will create an example application which will use the ABP Framework as backend for a mobile application which can run on an iOS or Andriod mobile device using Ionic Framework.

Source Code of the completed application is avalibale on Github


Here, is a preview of the Ionic App



If you haven't used ABP or Ionic Framework before you need to install and setup a few things. So lets get strated.


In order to install and run both ABP and Ionic Framework you first need to install the Node environment. You can either download and install it from here or if you are on Mac use Homebrew to install it like described here .

To test your setup, you can run the following two commands on the your CL:

node -v

npm -v

Make sure you can open your command line and get a result for both of the commands. Your versions might be different at the time of installing it but that should be ok if you are up to date!

Node Versions


You will also need Yarn insalled for ABP Framework, you can install Yarn through the npm package manager which comes bundled with Node.js when you install it on your system. Ensure that it is Yarn v1.20+ not v2. ABP Framework doesn't support Yarn v2

npm install -g yarn

Run the folowing command to check the version of Yarn.

Yarn Version


You will also need to have the ABP CLI installed to create the startup template. ABP CLI is a command line insterface that is used to automate some common tasks for the ABP framework based solution.

In order to install the ABP CLI you will need an IDE such as Visual Studio that uspports .Net 6.0+ installed

You can install it by running the following command on your CL:

dotnet tool install -g Volo.Abp.CLI

Once the ABP CLI is installed you can run the following command, at the time of writing this article, ABP Framework is at 5.2.2!

ABP Version

ABP Solution

We will be using ABP with Angular UI for our backend, so we will first create a new solution using the ABP CLI. Use the following command to create a ABP Angular Solution called IonicApp.

abp new IonicApp -u angular --mobile none --database-provider ef -csf

The -csf will create a IonicApp folder in side this folder you will have two folder angular which has the ABP Angular UI and aspnet-core which contains the layered ABP Solution

IonicApp.Db Migration Project

Now open the Ionic App Solution and navigate to the IonicApp.Db Migrator Project, then open the appsettings.json and add the following code

  "ConnectionStrings": {
    "Default": "Server=(LocalDb)\\MSSQLLocalDB;Database=IonicApp;Trusted_Connection=True"
  "IdentityServer": {
    "Clients": {
      "IonicApp_MobileApp": {
        "ClientId": "IonicApp_MobileApp",
        "ClientSecret": "1q2w3e*",
        "RootUrl": "http://localhost:8100"

We need to now setup the IonicApp_MobileApp client in our Identity Server, navigate to IonicApp.Domain project in the IdentityServer folder open IdentityServerDataSeedContributor.cs add the following code in the CreateClientsAsync() method. You will also need to turn off the Enable Integrated Terminal under Preferences > Other > Terminal

    private async Task CreateClientsAsync()
        var commonScopes = new[]

        var configurationSection = _configuration.GetSection("IdentityServer:Clients");

        //Other Clients ...

        //IonicApp_MobileApp Client
        var ionicMobileAppClientId = configurationSection["IonicApp_MobileApp:ClientId"];
        if (!ionicMobileAppClientId.IsNullOrWhiteSpace())
            var ionicClientRootUrl = configurationSection["IonicApp_MobileApp:RootUrl"]?.TrimEnd('/');

            await CreateClientAsync(
                name: ionicMobileAppClientId,
                scopes: commonScopes,
                grantTypes: new[] { "password", "client_credentials", "authorization_code" },
                secret: (configurationSection["IonicApp_MobileApp:ClientSecret"] ?? "1q2w3e*").Sha256(),
                requireClientSecret: false,
                redirectUri: ionicClientRootUrl,
                postLogoutRedirectUri: ionicClientRootUrl,
                corsOrigins: new[] { ionicClientRootUrl.RemovePostFix("/") }

If you are on a mac you may need to change your shell to /bin/zsh depending on the version of Mac you are running, you can do this in the AddInitalMigration() method which is located in file IonicAppDbMigrationService.cs in the the Data folder of the IonicApp.Domain project

Run the DB Migrator Project, you should see the below



Open the appsettings.json in the IonicApp.HttpApi.Host project and add http://localhost:8100 to CorsOrigins and RedirectAllowedUrls like below

  "App": {
    "SelfUrl": "https://localhost:44367",
    "ClientUrl": "http://localhost:4200",
    "CorsOrigins": "https://*,http://localhost:4200,http://localhost:8100",
    "RedirectAllowedUrls": "http://localhost:4200,https://localhost:44307:http://localhost:8100"
  "ConnectionStrings": {
    "Default": "Server=(LocalDb)\\MSSQLLocalDB;Database=IonicApp;Trusted_Connection=True"
  "AuthServer": {
    "Authority": "https://localhost:44367",
    "RequireHttpsMetadata": "false",
    "SwaggerClientId": "IonicApp_Swagger",
    "SwaggerClientSecret": "1q2w3e*"
  "StringEncryption": {
    "DefaultPassPhrase": "aBVYjSdEFT5E6GKf"

Set the IonicApp.HttpApi.Host to be the startup project and run it you should see the below


ABP Angular UI

Open the angular folder inside your IonicApp folder in Visual Studio Code and open the tearmial and run the following command

Yarn Start

You should see the below in your browsed


Login using the default username admin and password 1q2w3E* and navigate to Administration > Identity Management > Users and create some users like below


Ionic Framework

Now for the fun part, in order to create a Ionic Mobile App we need to install Ionic CLI by running the following command

npm install -g @ionic/cli

Navigate to the IonicApp folder and now run the following command,

ionic start ionic-app blank --type=angular --capacitor

The start argument creates a new Ionic Solution, the type of solution is Angular and --capacitor Capacitor is a cross-platform native runtime that makes it easy to build modern web apps that run natively on IOS, Android, and the Web.

Using Visual Studio open the folder Ionic-App you should see the below


Run the Ionic Solution with the following command, and you should see the below in the browser

ionic serve


We will now install the ABP Packages so we can take advantage of the power of ABP, run the following commands in the Terminal in the ionic-app folder

npm install @abp/ng.core

The @abp/ng.core package give you access to core functionality of ABP like ability to use the RestService, Localization, Authorization and Permissions ect etc...

npm install @abp/ng.schematics --save-dev

The @abp/ng.schematics is added as a development dependency to the project so we can generate the static proxy to access the ABP API


Open environment.ts under the src > environments folder and change it with the following code

import { Environment } from '@abp/ng.core';

const baseUrl = 'http://localhost:8100';

export const environment = {
  production: false,
  application: {
    name: 'IonicApp',
    logoUrl: '',
  oAuthConfig: {
    issuer: 'https://localhost:44367',
    redirectUri: baseUrl,
    clientId: 'IonicApp_MobileApp',
    responseType: 'code',
    scope: 'offline_access IonicApp',
    requireHttps: true,
  apis: {
    default: {
      url: 'https://localhost:44367',
      rootNamespace: 'IonicApp',
} as Environment;

Note that we are defining a environment constant which has the application, oAuthConfig and apis information which i have copied from the angular project which was created as part of the ABP solution. I have just changed the clientId in the oAuthConfig object to IonicAoo_MobileApp and the base url to http://localhost:8100


Open app.module.ts under the src > app folder and change it with the following code

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

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';

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

import { registerLocale } from '@abp/ng.core/locale';
import { CoreModule } from '@abp/ng.core';
import { environment } from 'src/environments/environment';

  declarations: [AppComponent],
  entryComponents: [],
  imports: [
      registerLocaleFn: registerLocale()
  providers: [{ provide: RouteReuseStrategy, useClass: IonicRouteStrategy }],
  bootstrap: [AppComponent],
export class AppModule {}

Note that we have are importing registerLocale and CoreModule from the @abp/ng.core package and we are have added the CoreModule.forRoot() which has the environment and registerLocale as parameters.

Generate Static Proxy

Now that we have imported the ABP packages we will now generate static proxies using the following command

abp generate-proxy -t ng -m identity -u https://localhost:44367


Note the port need to nbe the port 44367 on which your Ionic.HttpApi.Hostis running on, running thegenerate-proxycommand will create a proxy folder under thesrc > appcalledproxy.


Navigate to under the app > home folder and change its code to the following

import { Component } from '@angular/core';
import { AuthService, ConfigStateService, RestService } from '@abp/ng.core';
import { OAuthService } from 'angular-oauth2-oidc';
import { IdentityUserService } from '../proxy/volo/abp/identity';

  selector: 'app-home',
  templateUrl: '',
  styleUrls: [''],
export class HomePage  {
  title = 'custom-angular';

  users = [];

  tenantName = 'host';

  get hasLoggedIn(): boolean {
    return this.oAuthService.hasValidAccessToken();

  // eslint-disable-next-line @typescript-eslint/member-ordering
    private oAuthService: OAuthService,
    private authService: AuthService,
    private identityService: IdentityUserService,
    private config: ConfigStateService
  ) {

    this.tenantName = this.config.getDeep('');

    if (this.tenantName === null) {
      this.tenantName = 'host';


  login() {

  retrieveUsers() {
    this.identityService.getList({ maxResultCount: 10 }).subscribe((result) => {
      this.users = result.items;

  logout() {


Navigate to under the app > home folder and change its code to the following

<ion-header [translucent]="true">
      ABP Ionic App - {{ tenantName }}

<ion-content [fullscreen]="true">
  <ion-button expand="full" (click)="login()" *ngIf="!hasLoggedIn">Login</ion-button>
  <ion-button expand="full" (click)="retrieveUsers()" *ngIf="hasLoggedIn">Get Users</ion-button>
    <ion-item *ngFor="let user of users">
      {{ }}
  <ion-button expand="full" (click)="logout()" *ngIf="hasLoggedIn">Logout</ion-button>

Finally you have got your self a Mobile App

Run the Ionic Mobile App using the following command

ionic serve
