Replace event-based auto-expand trigger with Zustand state-driven
approach. Now both external file uploads and internal node drag use
the same isDragOver state as the single source of truth for folder
auto-expand timing (1s blink, 2s expand).
Simplify file drop hooks by removing the unnecessary useUnifiedDrag
wrapper that became redundant after internal node drag was migrated
to react-arborist's built-in system. Now useFolderFileDrop and
useRootFileDrop directly use useFileDrop, reducing code complexity
and eliminating unused treeChildren prop drilling.
Switch from native HTML5 drag to react-arborist's built-in drag system
for internal node drag-and-drop. The HTML5Backend used by react-arborist
was intercepting dragstart events, preventing native drag from working.
- Add onMove callback and disableDrop validation to Tree component
- Sync react-arborist drag state (isDragging, willReceiveDrop) to Zustand
- Simplify use-node-move to only handle API execution
- Update use-unified-drag to only handle external file uploads
- External file drops continue to work via native HTML5 events
Implement unified drag system that supports both internal node moves
and external file uploads with consistent UI feedback. Uses native
HTML5 drag API with shared visual states (isDragOver, isBlinking,
DragActionTooltip showing 'Move to' or 'Upload to').
Move searchTerm from props drilling to zustand store for cleaner
architecture. Remove unnecessary controlled/uncontrolled pattern
and unused debounce logic since search is pure frontend filtering.
- Add fileTreeSearchTerm state to file-tree-slice
- Remove useState and props from main.tsx
- Simplify sidebar-search-add.tsx to read/write store directly
- Add empty state UI with reset filter button
Remove the Office file placeholder that only showed "Preview will be
supported in a future update" without any download option. Office files
(pdf, doc, docx, xls, xlsx, ppt, pptx) now fall through to the generic
"unsupported file" handler which provides a download button.
Removed:
- OfficeFilePlaceholder component
- isOfficeFile function and OFFICE_EXTENSIONS constant
- isOffice flag from useFileTypeInfo hook
- i18n keys for officePlaceholder
This simplifies the file type handling to just three categories:
- Editable: markdown, code, text files → editor
- Previewable: image, video files → media preview
- Everything else: download button
Change useSkillFileData to use isEditable instead of isMediaFile:
- Editable files (markdown, code, text) fetch file content for editing
- Non-editable files (image, video, office, unsupported) fetch download URL
This fixes the download button for unsupported files which was incorrectly
using file content (UTF-8 decoded garbage) instead of the presigned URL.
Extract business logic into dedicated hooks to reduce component complexity:
- useFileTypeInfo: file type detection (markdown, code, image, video, etc.)
- useSkillFileData: data fetching with conditional API calls
- useSkillFileSave: save logic with Ctrl+S keyboard shortcut
Also fix Vercel best practice: use ternary instead of && for conditional rendering.
Previously, media files were fetched via getFileContent API which decodes
binary data as UTF-8, resulting in corrupted strings that cannot be used
as img/video src. Now media files use getFileDownloadUrl API to get a
presigned URL, enabling proper preview of images and videos of any size.
- Add constants.ts with ROOT_ID, CONTEXT_MENU_TYPE, NODE_MENU_TYPE
- Add root utilities to tree-utils.ts (isRootId, toApiParentId, etc.)
- Replace '__root__' with ROOT_ID for consistent root identifier
- Replace inline 'blank'/'root' strings with constants
- Use NodeMenuType for type-safe menu type props
- Remove duplicate ContextMenuType from types.ts, use from constants.ts
Remove redundant createTargetNodeId and use selectedTreeNodeId for both
visual highlight and creation target. This simplifies the state management
by having a single source of truth for tree selection, similar to VSCode's
file explorer behavior where both files and folders can be selected.
Update frontend to use new backend API:
- save_config now accepts optional 'activate' parameter
- activate endpoint now requires 'type' parameter ('system' | 'user')
When switching to managed mode, call activate with type='system' instead
of deleting user config, so custom configurations are preserved for
future use.
Split use-file-operations.ts (248 lines) into smaller focused hooks:
- use-create-operations.ts for file/folder creation and upload
- use-modify-operations.ts for rename and delete operations
- use-file-operations.ts now serves as orchestrator maintaining backward compatibility
Extract TreeNodeIcon component from tree-node.tsx for cleaner separation of concerns.
Add brief comments to drag hooks explaining their purpose and relationships.
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.
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.
Use explicit StateCreator<FullStore, [], [], SliceType> pattern instead of
StateCreator<SliceType> for all skill-editor slices. This enables:
- Type-safe cross-slice state access via get()
- Explicit type contracts instead of relying on spread args behavior
- Better maintainability following Lobe-chat's proven pattern
Extract all type definitions to types.ts to avoid circular dependencies.
Replace explicit parameter destructuring with spread args pattern to
eliminate `as unknown as` type assertions when composing sub-slices.
This aligns with the pattern used in the main workflow store.
Consolidate file type derivations into a single useMemo with stable
dependencies (currentFileNode?.name and currentFileNode?.extension)
to help React Compiler track stability.
Extract originalContent as a separate variable to avoid property access
in useCallback dependencies, which caused Compiler to infer broader
dependencies than specified.
Wrap isEditable in useMemo to help React Compiler track its stability
and preserve memoization for callbacks that depend on it. Also replace
Record<string, any> with Record<string, unknown> to satisfy no-explicit-any.
Move activeTabId and fileMetadata reads from selector subscriptions to
getState() calls inside the callback. These values were only used in the
insertTools callback, not for rendering, causing unnecessary re-renders
when they changed.
Previously, any edit would mark the file as dirty even if the content
was restored to its original state. Now we compare against the original
content and clear the dirty flag when they match.
Split the monolithic skill-editor-slice.ts into a dedicated directory with
individual slice files (tab, file-tree, dirty, metadata, file-operations-menu)
to improve maintainability and code organization.
Reduce initial bundle size by dynamically importing SkillMain
component. This prevents loading the entire Skill module (including
Monaco and Lexical editors) when users only access the Graph view.
Add search functionality to skill sidebar using react-arborist's built-in
searchTerm and searchMatch props. Search input is debounced at 300ms and
filters tree nodes by name (case-insensitive). Also add success toast for
rename operations.
Replace getAncestorIds(treeData) with node.parent chain traversal
for more efficient ancestor lookup. This avoids re-traversing the
tree data structure and uses react-arborist's built-in parent refs.
Also rename hook to useSyncTreeWithActiveTab for clarity.
Use split button pattern to separate main content area from more button.
This prevents click events on the more button from bubbling up to the
parent element's click/double-click handlers, which caused unintended
file opening when clicking the menu button multiple times.
Move SkillEditorSlice from injection pattern to core workflow store,
making it available to all workflow contexts (workflow-app, chatflow,
and future rag-pipeline).
- Add createSkillEditorSlice to core createWorkflowStore
- Remove complex type conversion logic from workflow-app/index.tsx
- Remove optional chaining (?.) and non-null assertions (!) from components
- Simplify slice composition with type assertions via unknown
Lexical editor only uses initialConfig.editorState on mount, ignoring
subsequent value prop changes when the component is reused by React.
Adding key={activeTabId} forces React to remount editors when switching
tabs, ensuring correct content is displayed.
Refactor the skill editor state management from a standalone Zustand store
with Context provider pattern to a slice injection pattern that integrates
with the existing workflow store. This aligns with how rag-pipeline already
injects its slice.
- Remove SkillEditorProvider and SkillEditorContext
- Export createSkillEditorSlice for injection into workflow store
- Update all components to use useStore/useWorkflowStore from workflow store
- Add SkillEditorSliceShape to SliceFromInjection union type
- Use type-safe slice creator args without any types
Merge file-node-menu.tsx and folder-node-menu.tsx into a single
declarative NodeMenu component that uses type prop to determine
menu items. Add cva-based variant support to MenuItem for consistent
destructive styling.
- Use es-toolkit throttle with leading edge to prevent folder toggle
flickering on double-click (3 toggles reduced to 1)
- Add validation in pinTab to check if file exists in openTabIds
- Single-click file in tree opens in preview mode (temporary, replaceable)
- Double-click file opens in pinned mode (permanent)
- Preview tabs display with italic filename
- Editing content auto-converts preview tab to pinned
- Double-clicking preview tab header converts to pinned
- Only one preview tab can exist at a time
Add TreeEditInput component for inline file/folder renaming with keyboard
support (Enter to submit, Escape to cancel). Add TreeGuideLines component
to render vertical indent lines based on node depth for better visual
hierarchy in the tree view.
Reorganize file tree components into dedicated `file-tree` subdirectory
for better code organization.
Extract repeated appId retrieval and tree data fetching patterns into
dedicated hooks (useSkillAssetTreeData, useSkillAssetNodeMap) to reduce
code duplication across 6 components and leverage TanStack Query's
select option for efficient nodeMap computation.
- Convert div with onClick to proper button elements for keyboard access
- Add focus-visible ring styles to all interactive elements
- Add ARIA attributes (role, aria-selected, aria-expanded) to tree nodes
- Add keyboard navigation (Enter/Space) support to tree items
- Mark decorative icons with aria-hidden="true"
- Add missing i18n keys for accessibility labels
- Fix typography: use ellipsis character (…) instead of three dots
- Add useIsMutating hook to track ongoing mutations
- Apply pointer-events-none and opacity-50 when mutating
- Prevents user interaction during file operations
- Move DropTip component outside the tree flex container
- Use Fragment to group tree container, DropTip and context menu
- DropTip is now an independent fixed element at the bottom
- Replace fixed height={1000} with dynamic containerSize.height
- Use useSize hook from ahooks to observe container dimensions
- Fallback to 400px default height for initial render
- Fixes scroll issues when collapsing folders
