Understanding Common AppGyver Issues

Users of AppGyver frequently face the following challenges:

• App build failures and deployment errors.
• API and backend connectivity problems.
• Performance issues and slow app responsiveness.
• UI rendering inconsistencies across devices.

Root Causes and Diagnosis

App Build Failures and Deployment Errors

Build failures often result from incorrect configurations, missing assets, or dependency issues. Check build logs for errors:

https://platform.appgyver.com/app-builder/builds

Ensure all required assets are correctly linked:

Check under "Assets" in AppGyver Composer

Validate build settings in the AppGyver dashboard:

Ensure correct bundle identifier and version number

API and Backend Connectivity Problems

API integration issues can cause data fetching failures. Test API endpoints directly:

curl -X GET https://api.example.com/endpoint -H "Authorization: Bearer TOKEN"

Ensure API configurations in AppGyver are correct:

Data > REST API Integration > Verify base URL and authentication settings

Check for CORS policy errors in browser console:

console.log(response.error);

Performance Issues and Slow App Responsiveness

Excessive page loads, unoptimized queries, or inefficient logic can slow down apps. Use performance profiling tools:

Enable "Debugging Mode" in AppGyver preview

Reduce data fetching overhead with pagination:

Limit API responses: https://api.example.com/data?page=1&limit=10

Optimize logic flows by minimizing unnecessary loops:

Use AppGyver’s "Formula" functions for efficient calculations

UI Rendering Inconsistencies Across Devices

Different screen sizes and resolutions may cause UI elements to appear misaligned. Use relative positioning:

Set "Width" and "Height" to "% of screen width/height"

Enable responsive design settings:

Enable "Flexbox" layout for dynamic positioning

Test app rendering on multiple devices using AppGyver preview:

Fixing and Optimizing AppGyver Applications

Ensuring Successful App Builds

Check build logs, validate asset linking, and ensure correct deployment settings.

Fixing API and Backend Connectivity

Test API endpoints, verify authentication settings, and check for CORS policy errors.

Optimizing App Performance

Enable debugging mode, use pagination for API requests, and streamline logic flows.

Handling UI Rendering Issues

Use relative positioning, enable flexbox layouts, and test across different devices.

Conclusion

AppGyver provides a powerful low-code environment for mobile and web apps, but build failures, API issues, performance slowdowns, and UI inconsistencies can impact development. By systematically troubleshooting these problems and optimizing app performance, developers can build stable and responsive applications.
