fix: search hgf repo and downloaded filter

[urmauur]

Describe Your Changes

This pull request updates the model search and filtering logic in the Hub page to improve the handling of HuggingFace repository searches and the "Downloaded Only" toggle. The changes ensure that switching between viewing all models and only downloaded models properly resets or re-triggers searches, and that duplicate models are prevented by checking both model name and developer.

Improvements to search and filtering behavior:

• The HuggingFace repository search is now only triggered when not in "Downloaded Only" mode, preventing unnecessary searches.
• When toggling "Downloaded Only" back to "All models," the HuggingFace search is re-triggered if the search value is a repository path or URL, ensuring the UI updates correctly.
• Switching to "Downloaded Only" mode resets the selected HuggingFace repository to null for consistency.

Improvements to duplicate model prevention:

• The logic for preventing duplicate models now checks both the trimmed model name and developer, ensuring that models from different developers with the same name are handled correctly. [1] [2]

Important

Improves HuggingFace repo search and filtering logic in Hub component, ensuring proper handling of "Downloaded Only" mode and preventing duplicate models by checking both name and developer.

• Search and Filtering:
  • fetchHuggingFaceModel() now only triggers when not in "Downloaded Only" mode.
  • Re-triggers HuggingFace search when toggling "Downloaded Only" back to "All models" if search value is a repo path or URL.
  • Resets selected HuggingFace repo to null when switching to "Downloaded Only" mode.
• Duplicate Prevention:
  • Checks both model name and developer to prevent duplicates in fetchHuggingFaceModel().
• Misc:
  • Adjusted handleSearchChange() to clear previous repo info and conditionally fetch models based on showOnlyDownloaded.

  Good: Added condition to avoid triggering a HuggingFace repo search in 'Downloaded Only' mode. This prevents unnecessary network calls when the toggle is active.

  Nice improvement: The duplicate check now includes a comparison of both trimmed model names and developers. This fixes the issue with models by different authors sharing the same name.

1. web-app/src/routes/hub/index.tsx:197

• Draft comment:
  Consider wrapping fetchHuggingFaceModel in a useCallback to avoid recreating the function on every render and to ensure it captures the latest values of dependencies (like sources and huggingfaceToken).

  Consider adding a cleanup effect to clear addModelSourceTimeoutRef on component unmount to prevent any delayed execution after unmount.

3. web-app/src/routes/hub/index.tsx:216

• Draft comment:
  Double-check that the duplication check using .split('/') and pop is robust for all expected HuggingFace repo URL formats. If model names differ in format, this may lead to false negatives.
