### TL;DR
Refactored `SpecProvider` singleton access pattern and reorganized adapter/extension code structure.
### What changed?
- Changed `SpecProvider.getInstance()` to `SpecProvider._` for cleaner singleton access
- Moved adapter/extension code from `_common` directory to dedicated `adapters` and `extensions` folders
- Consolidated adapter extensions into a single file
- Removed unused dependencies from package.json
- Deleted unnecessary schema files
- Extracted `MobileSpecsPatches` class into the mobile patching code
- Updated all references to use the new `SpecProvider._` accessor
### How to test?
- Verify all specs are properly registered and accessible via `SpecProvider._`
- Test adapter functionality for HTML, Markdown, Notion HTML and plain text
- Check mobile-specific features and patches work correctly
- Ensure preview functionality works in both page and edgeless modes
### Why make this change?
- Improves code organization by properly separating adapters and extensions
- Simplifies singleton access pattern
- Removes unnecessary dependencies and files
- Makes the codebase more maintainable by consolidating related functionality
### TL;DR
Moved image proxy middleware and adapter extensions to their respective packages and introduced a new spec provider for adapter registration.
### What changed?
- Relocated `defaultImageProxyMiddleware` from blocks to `@blocksuite/affine-block-image`
- Moved `PresentTool` from fragment-frame-panel to block-frame
- Created new adapter extension specs for HTML, Markdown, and Notion HTML
- Introduced a spec provider pattern for adapter registration
- Removed direct transformer references from RootService
- Updated imports across affected files to use new locations
### How to test?
1. Verify image proxy functionality works in exports and imports
2. Test HTML, Markdown, and Notion HTML adapters still function correctly
3. Confirm presentation mode works with the relocated PresentTool
4. Check that all file import/export operations continue to work as expected
### Why make this change?
This reorganization improves code modularity by placing features in their logical packages and introduces a more maintainable pattern for adapter registration. The spec provider pattern makes it easier to manage and extend adapter functionality while reducing coupling between components.
### Changed
- Add new image block to render dnd preview
- Fixed the bug that dragging uploaded image does not have width and height
- Fixed the bug that drag image block from page to edgeless does not have width and height
- Better edgeless dnd preview
### Changed
- Added support for changing the preview offset during dragging.
- Fixed the preview rendering for embed block and surface-ref block
- Resolved an issue where the host element might be reused in certain cases, which could cause unexpected behavior
- Moved viewport-related constants and methods to a more appropriate location
### Changed
- Refactored BlockSuite drag-and-drop using @atlaskit/pragmatic-drag-and-drop/element/adapter.
- Updated block dragging to use the new drag-and-drop infrastructure.
### BlockSuite DND API
Access the BlockSuite drag-and-drop API via `std.dnd`. This is a lightweight wrapper around pragmatic-drag-and-drop, offering convenient generic types and more intuitive option names.
#### Drag payload structure
There's some constrain about drag payload. The whole drag payload looks like this:
```typescript
type DragPayload = {
entity: {
type: string
},
from: {
at: 'blocksuite',
docId: string
}
}
```
- The `from` field is auto-generated—no need for manual handling.
- The `entity` field is customizable, but it must include a `type`.
All drag-and-drop methods accept a generic type for entity, ensuring more accurate payloads in event handlers.
```typescript
type BlockEntity = {
type: 'blocks',
blockIds: string[]
}
dnd.draggable<BlockEntity>({
element: someElement,
setDragData: () => {
// the return type must satisfy the generic type
// in this case, it's BlockEntity
return {
type: 'blocks',
blockIds: []
}
}
});
dnd.monitor<BlockEntity>({
// the arguments is same for other event handler
onDrag({ source }) {
// the type of this is BlockEntity
source.data.entity
}
})
```
#### Drop payload
When hover on droppable target. You can set drop payload as well. All drag-and-drop methods accept a second generic type for drop payload.
The drop payload is customizable. Additionally, the DND system will add an `edge` field to the final payload object, indicating the nearest edge of the drop target relative to the current drag position.
```typescript
type DropPayload = {
blockId: string;
}
dnd.dropTarget<BlockEntity, DropPayload>({
getData() {
// the type should be DropPayload
return {
blockId: 'someId'
}
}
});
dnd.monitor<BlockEntity, DropPayload>({
// drag over on drop target
onDrag({ location }) {
const target = location.current.dropTargets[0];
// the type is DropPayload
target.data;
// retrieve the nearest edge of the drop target relative to the current drop position.
target.data.edge;
}
})
```
