Add ability to choose between "Managed by Dify" (using system config)
and "Bring Your Own API Key" modes when configuring E2B sandbox provider.
This allows Cloud users to use Dify's pre-configured credentials or
their own E2B account for more control over resources and billing.
When dragging files over a closed folder, the highlight now blinks
during the second half of the 2-second hover period to signal that
the folder is about to expand. This provides better visual feedback
similar to VSCode's drag-and-drop behavior.
Use Promise.all for concurrent file uploads instead of sequential
processing, improving upload performance for multiple files. Also
add isFileDrag check to handleFolderDragOver for consistency with
other drag handlers.
Enable users to drag files from their system directly into the file tree
to upload them. Files can be dropped on the tree container (uploads to root)
or on specific folders. Hovering over a closed folder for 2 seconds auto-
expands it. Uses Zustand for drag state management instead of React Context
for better performance.
The previous refactor inadvertently passed undefined nodeId for blank
area menus, causing root-level folder creation/upload to fail. This
restores the original behavior by explicitly passing 'root' when the
context menu type is 'blank'.
Consolidate menu components by extending NodeMenu to support a 'root'
type, eliminating the redundant BlankAreaMenu component. This reduces
code duplication and simplifies the context menu logic by storing
isFolder in the context menu state instead of re-querying tree data.
When file content is not in JSON format (e.g., newly uploaded files),
return the raw content instead of empty string to ensure files display
correctly.
Remove types that don't match backend API:
- AppAssetFileContentResponse (unused, had extra metadata field)
- CreateFilePayload (unused, FormData built manually)
- metadata field from UpdateFileContentPayload
Add right-click context menu for file tree blank area with New File,
New Folder, and Upload Files options. Also align search input and
add button styles to match Figma design specs (24px height, 6px radius).
Remove label, description, and icon fields from SandboxProvider type
as they are no longer returned by the backend API. Use i18n translations
to display provider labels instead of relying on API response data.
