Build with React Native and Expo in VULK
VULK supports real React Native/Expo projects with source files and a browser preview. Start from the VULK app gallery, choose React Native / Expo, and copy an app into your account. You can inspect its code, test the preview and take the source into the Expo toolchain.
The current entry point for Expo is the gallery. For a new mobile app generated directly from a description, use the Flutter workflow.
Start with a working app
- Choose a gallery app close to your idea and copy it.
- Open the project and its preview. Test navigation, search, forms and any saved state that matters to your app.
- Inspect
package.json, the app configuration and the source files. Confirm the actual dependencies and routes before changing them. - Export the source and continue with the project’s package manager and Expo development tools.
On 18 October 2026, we tested this route with the Ruzzo recipe app: the copied project contained 33 files, and its preview supported search, recipe details, servings changes and adding ingredients to a shopping list. The example’s shopping list returned to its seed data after a reload. Add and test persistent storage when your product requires it.
Preview on a device and prepare native builds
Install the exported project’s dependencies and run npx expo start. Use Expo Go when the project’s native dependencies are supported; otherwise follow Expo’s development-build workflow. Test hardware features and permissions on a real device.
Configure your app identifiers, signing and build profiles using the official EAS Build guide. EAS produces the native packages used in your Android or iOS release workflow. Complete the store listing and submit through your own developer accounts; a browser preview and a store-approved release are different stages.
Which mobile route should you choose?
Choose Expo for an existing gallery project or a React/TypeScript workflow. Choose Flutter for a new prompt-led app with the Android APK/AAB build controls inside VULK. Both routes use mobile source code you can inspect and continue developing.
See current mobile build instructions for the available controls. Plans, source-export access and commercial conditions come from VULK pricing.
