WalkthroughThe pull request reorganizes the README documentation and refines the model download logic in the example application. The README now includes a revised introduction, clearer installation instructions, updated usage examples with state management for loading models, and new sections for custom model downloads and supported models. In the example, the download routine now checks for an existing file before proceeding, enhances error handling with try-catch blocks, and provides clearer logging of the download process. No changes were made to public API declarations. Changes

28-39: Good file existence check implementation!The addition of a file existence check before downloading is an excellent improvement that prevents unnecessary re-downloads and improves performance. The code properly checks if the file exists with
FileSystem.getInfoAsync()and returns the local path if it does.🧰 Tools

50-56: Good error handling for download results.The code now properly checks for a successful download result and throws an appropriate error if the download fails. This is a good practice that prevents silent failures and provides clear error messages.

57-60: Improved error handling with try-catch.The addition of a try-catch block around the download logic is a great improvement for error handling. It catches any errors during the download process, logs them properly, and returns null to indicate failure.

7-14: Excellent introduction improvements!The new introduction effectively communicates the value proposition of the library. It clearly emphasizes on-device inference capabilities, privacy benefits, and reduced latency - which are key selling points for potential users.
15-22: Well-structured key features section.The bullet points format makes the key features easily scannable, and the bold headings help emphasize the main benefits. This section effectively showcases the library's strengths.
25-39: Clear installation instructions with platform-specific guidance.The installation section is well-organized with numbered steps and separate instructions for React Native and Expo. This clarity helps users follow the correct installation path for their specific environment.
41-67: Well-organized platform configuration using collapsible sections.Using collapsible details elements for platform-specific configuration is an excellent approach. The formatting with bold summary headings makes it easy to find the relevant information.
71-82: Clear Babel configuration instructions.The Babel configuration example is well-formatted and includes comments to indicate where users should integrate with their existing configuration.
91-152: Improved usage example with state management.The updated usage example is much more comprehensive, including:
- Proper state management for loading states and model readiness
- Error handling during model initialization
- Better UI feedback during loading and generation
This provides a more realistic implementation that users can follow.
154-189: Excellent custom model download example.This new section provides a valuable example for handling model downloads with progress tracking, which aligns perfectly with the changes in the App.tsx file. The example includes:
- File existence checking to avoid redundant downloads
- Progress tracking with percentage completion
- Proper error handling
This will be especially useful for Expo users who need to implement custom downloading logic.
191-202: Valuable supported models section with size information.The new supported models table is an excellent addition that provides users with concrete examples of models they can use. Including the model size and brief descriptions helps users make informed choices about which models to use based on their app's constraints.
203-227: Updated external links section with ONNX documentation.The addition of the ONNX Format Documentation link is helpful for users who want to learn more about the format or convert their own models.
