Microservice Solution: Mobile Applications

You must have an ABP Business or a higher license to be able to create a microservice solution.

The current ABP Studio modern microservice solution template can optionally generate a mobile application under apps/mobile/react-native.

The modern template does not generate a MAUI mobile application. Its mobile choices are None and React Native.

The Mobile Gateway

If you enable the mobile application, an API gateway named MobileGateway is added under gateways/mobile. The React Native client calls backend APIs through this gateway.

See API Gateways for the shared gateway structure.

Authentication

The generated React Native app is configured in Environment.ts with:

• the AuthServer issuer URL
• the MobileGateway base URL
• the ReactNative client id and scopes

At runtime, the mobile client uses the password grant to exchange credentials for access and refresh tokens at the AuthServer /connect/token endpoint, then sends bearer tokens to backend APIs through the MobileGateway. Account-related operations such as registration, password reset, profile picture management, and logout use the generated API client under src/api.

Built-in Capabilities

The generated mobile app already includes screens and flows for:

• sign in, registration, forgot password, and reset password
• account and profile picture management
• user-facing settings such as language, theme, and logout

Localization is handled by the bundled locale files under src/locales and src/services/LocalizationService.ts. Theme handling lives under src/theme.

Solution Structure

The React Native application is based on React Native and Expo. The main files and folders in apps/mobile/react-native are:

• Environment.ts: runtime URLs, client id, scopes, and default localization resource name.
• src/api: HTTP clients for token, account, and application configuration calls.
• src/components: reusable UI components.
• src/contexts: shared React contexts, including localization context.
• src/hooks: reusable React hooks.
• src/interceptors: request and response interception for the API client.
• src/locales: bundled UI translations.
• src/navigators: drawer, stack, and tab navigation definitions.
• src/screens: application pages such as login, home, settings, and account flows.
• src/services: cross-cutting services such as localization helpers.
• src/store: Redux actions, listeners, reducers, and selectors.
• src/theme, src/types, src/utils: shared theming, typings, and helper utilities.

Running the Application

The React Native app is not started by the ABP Studio solution runner. Run AuthServer, MobileGateway, and the required backend services first, then start the mobile app with the standard React Native / Expo toolchain.

For Android emulators or devices, map the development ports before testing:

adb reverse tcp:<mobile-gateway-port> tcp:<mobile-gateway-port>
adb reverse tcp:<auth-server-port> tcp:<auth-server-port>

Use the ports assigned to MobileGateway and AuthServer in your generated solution.
