This walkthrough follows the historical stack documented for JHipster 6.4.1, Ionic CLI 5.4.4, and Ionic for JHipster 4.3.0. Pin those versions if you are reproducing it; the current blueprint targets a much newer JHipster release, so do not assume the 2019 setup works unchanged with current tools.
What Ionic for JHipster generates
Ionic for JHipster is a JHipster Blueprint that generates an Ionic client. It consumes the API exposed by your JHipster backend; it does not replace the Spring Boot application. You can use the client in a browser during development, add PWA support, or prepare a Cordova project for iOS or Android.
This guide is version-locked rather than a general installation recipe. The historical setup uses JHipster 6.4.1, Ionic for JHipster 4.3.0, Ionic CLI 5.4.4, Yeoman, Java 8 or newer, Node.js 10 or newer, and Docker. Those are the documented prerequisites for reproducing that stack, not recommendations for a new production project today.
Choose a version path before you begin
| Path | When it makes sense | What to expect |
|---|---|---|
| Pinned historical stack | You need to reproduce the JHipster 6 tutorial or maintain an application built with it. | Use the documented versions together: JHipster 6.4.1, Ionic CLI 5.4.4, and Ionic for JHipster 4.3.0. Older Java, Node, Cordova, and IDE requirements may make setup more difficult on current machines. |
| Current blueprint | You are starting a new application or upgrading an existing one. | Marketplace metadata lists compatibility with JHipster 8.11.0. Check the blueprint’s current documentation and adapt the workflow to its supported toolchain instead of mixing current releases with these historical commands. |
The commands below follow the pinned path. A successful global installation does not guarantee compatibility if you substitute a newer JHipster generator or Ionic blueprint.

Generate the JHipster backend
Install the historical JHipster generator
With a compatible Node.js installation, install the specified generator version:
npm i -g generator-jhipster@6.4.1Create an OAuth 2.0 backend
Create a directory for the backend and generate a Spring Boot application configured for OAuth 2.0/OIDC authentication. The tutorial’s JDL-based setup uses baseName oauth2, authenticationType oauth2, Gradle, and Protractor. You can enter equivalent choices in the generator prompts or use the tutorial’s JDL shortcut; the important point is that the backend is configured for the same identity provider that the mobile client will use.
Start the backend with its OIDC issuer, client ID, and client secret supplied through environment variables. Keep secrets out of source control, shell history, and checked-in configuration. The precise variable names depend on the generated application’s configuration; use the names it expects rather than inventing new ones. Confirm that the API starts and is reachable before generating or debugging the mobile client.

Configure Okta for a native OIDC client
The documented login example uses Okta. Create a native application for the Ionic client and use Authorization Code with PKCE. A native app cannot safely keep a client secret, so its login flow differs from the confidential client credentials used by the backend. The backend and mobile application have distinct client configuration: the backend gets its own OIDC settings, while the Ionic app needs the native application’s client ID.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
- Create the Okta native application and enable the OIDC flow appropriate for a public native client using PKCE.
- Register the local and device redirect and logout URIs required by the generated Ionic authentication configuration. The redirect URI values must match exactly on both sides; use the values expected by this version of the generated app rather than guessing a URI.
- Add a groups claim to the token configuration, with
ROLE_ADMINandROLE_USERrepresented as groups. The JHipster application uses these roles for authorization. - Keep the mobile client ID available for the Ionic configuration step. Do not put a client secret in the native app.
Account setup instructions have changed since the original tutorial: an Okta notice dated May 2025 says the Integrator Free Plan replaced the former Developer Edition and the Okta CLI was deprecated. Follow current Okta account and console guidance rather than relying on old account-creation or CLI steps.
Generate the Ionic client beside the backend
Install Ionic CLI and the blueprint
From a terminal with the historical Node.js toolchain, install Ionic CLI 5.4.4, Yeoman, and Ionic for JHipster 4.3.0:

npm i -g ionic@5.4.4 yo generator-jhipster-ionic@4.3.0Run the blueprint generator
Make a sibling directory for the client, then run the Yeoman generator from that directory:
yo jhipster-ionicIn the prompts, enter mobile as the client name and provide the path to the backend application as the application location. The intended layout is a backend directory and a mobile client directory next to it. The maintained blueprint also documents invoking a blueprint through JHipster with jhipster --blueprints ionic; for this version-specific workflow, use the generator invocation above.

From the client directory, start the browser development server:

yo jhipster-ionic:entity album- Choose the existing backend entity when prompted.
- Point the generator to the backend application, such as
../appwhen your directory layout matches the tutorial’s example. - Review the merge or regeneration prompt before accepting changes. If you have edited generated client files, inspect proposed changes and preserve your custom work.
Repeat the command for other existing entities, such as photo or tag. The generated list, detail, and edit screens call the JHipster API, so changes made through the mobile client can appear in the web application’s entity list when both clients use the same backend and data.
For a project that has not yet modeled its data, JDL can define backend entities before client generation. The historical shortcut described here configures the application authentication and build choices; entity generation remains a separate step that points the Ionic generator at existing backend entities.
Prepare a Cordova build for iOS
- From the Ionic project, run
ionic cordova prepare ios. Install the iOS platform when prompted. - Open the generated workspace in Xcode.
- Configure signing for the simulator or the Apple developer team and device you intend to run.
- Select the target simulator or device in Xcode and run the app.
Preparation creates the native project; it does not configure Apple signing on your behalf. Resolve signing and platform compatibility issues in Xcode before treating the app as ready to distribute.
Prepare a Cordova build for Android
- Use Java 8 for this historical stack, then run
ionic cordova prepare androidfrom the Ionic project. Install the Android platform when prompted. - Open
platforms/androidin Android Studio. If the IDE prompts for a Gradle upgrade, handle that prompt as part of bringing this older project into the installed Android toolchain. - Set the Android activity’s
launchModetosingleTask, as required by the tutorial’s mobile authentication setup. - For an emulator using a backend running on the development computer, forward its API port with
adb reverse tcp:8080 tcp:8080. - Run the app from Android Studio on the emulator or connected device and test API access and sign-in.
The port-forward command maps the emulator’s port 8080 to the host’s port 8080. If the backend listens on a different port, this exact command will not connect it; adjust the mapping to the backend’s actual local port.

- Browser development: Use
ionic serveto run the client locally while iterating on screens and API calls. - PWA: The blueprint README documents adding PWA support with
ng add @angular/pwa. This adds a web-app delivery path; it is distinct from building an iOS or Android package. - Cordova iOS or Android: Use the platform preparation commands and complete the relevant IDE, signing, and authentication configuration. The documented native workflow is Cordova-based.
Keep the version boundary in view
This workflow is useful for reproducing a JHipster 6 application, but its generator and native-build dependencies come from a 2019-era stack. The maintained blueprint’s compatibility metadata lists JHipster 8.11.0, which signals that current releases have moved beyond the versions in this tutorial. For a new project, follow the current blueprint’s own installation and migration guidance; for an existing project, preserve a known-compatible toolchain and plan upgrades as a separate compatibility task.
