Creating a Native Portal Component for React Native

[RameshTigeen]

Introduction:
React Native Paper is a popular UI library that provides a Portal component to manage rendering of elements outside the main hierarchy, such as modals, tooltips, or dialogs. While React Native Paper offers excellent functionality, its package size can be a concern for projects where lightweight optimization is crucial. To address this, we propose building a native Portal component within our codebase to mimic and optimize the behavior of React Native Paper's Portal without relying on the library.

Benefits of Building a Native Portal Component:

Reduced Package Size:
By eliminating React Native Paper dependency solely for the Portal component, we can reduce the bundle size, improving performance, especially for mobile applications with constrained resources.

Full Customization:
Implementing our own Portal component allows for complete control over its behavior, styling, and integration with our app's ecosystem.

Optimized Performance:
A native implementation can be tailored to specific project requirements, avoiding general-purpose abstractions that might not align with our use cases.

Consistent Development:
Maintaining this functionality in-house ensures alignment with the overall architecture and coding standards of the project.

Proposed Implementation Strategy:

Research Existing Approaches:
Study the behavior and API of React Native Paper’s Portal component. Explore its use cases to ensure our implementation covers the core functionalities.

Design the API:
Define a lightweight API for the component. For example:

import { Portal, PortalProvider } from 'react-native';

function App() {
  return (
    <PortalProvider>
      <YourMainComponent />
      <Portal>
        <YourModalOrDialog />
      </Portal>
    </PortalProvider>
  );
}

Develop Core Features:

Provider and Context: Manage a global registry for components rendered in portals.

Portal Component: Render children outside the parent view hierarchy.

Event Handling: Ensure proper bubbling of gestures and interactions.

Optimize for React Native:

Ensure compatibility with React Native’s rendering cycle and gesture system.

Minimize re-renders and memory usage.

Testing and Validation:

Test with common use cases like modals, tooltips, and alerts.

Validate the implementation on both iOS and Android platforms.

Challenges and Considerations:

Gesture Handling:
Implement robust gesture handling to avoid issues with overlapping elements or misaligned user interactions.

Performance in Complex Views:
Test performance in views with heavy animations or intensive rendering.

Future Maintenance:
Ensure that the implementation is modular and scalable for future enhancements.

Conclusion:
Creating a native Portal component provides significant advantages in terms of optimization, customization, and alignment with project needs. While this involves additional initial effort, the long-term benefits to performance and maintainability make it a worthwhile investment for our React Native project.
