To sync a note, open the note you want to sync and use the "Share to NotionNext" command from the command palette or the note context menu. This will create a new page in your Notion database with the content of your Obsidian note.
## Attachment Upload
The plugin automatically detects and uploads local attachments (images, PDFs, etc.) from your notes to Notion.
### Supported Attachment Formats
**Image formats:**
- PNG, JPG, JPEG, GIF, WebP, SVG, HEIC, TIF, TIFF, BMP
**Other formats:**
- PDF
### Supported Link Formats
Currently supported:
#### Wikilink Format (Recommended)
```markdown
![[image.png]]
![[folder/image.png]]
![[image.png|alt text]]
[[document.pdf]]
[[folder/document.pdf]]
```
#### Standard Markdown Format
```markdown
![alt text](image.png)
![alt text](folder/image.png)
![](./relative/path/image.png)
[document.pdf](document.pdf)
[document.pdf](folder/document.pdf)
```
#### TODO
- [ ] Obsidian URL Format
```markdown
![](obsidian://open?vault=MyVault&file=path/to/image.png)
```
- [ ] App URL Format
```markdown
![](app://local/path/to/image.png)
```
### How Attachment Upload Works
1. **Auto Detection**: During sync, the plugin scans your note content and identifies all local attachment references
2. **Upload to Notion**: Detected attachments are uploaded via the Notion File Upload API
3. **Link Replacement**: After successful upload, local links are replaced with Notion file references
4. **Image Display**: Images are displayed as Notion image blocks
5. **File Embedding**: Non-image files like PDFs are embedded as file blocks
### Notes
- Attachment references inside code blocks are not processed
- External URLs (`http://` or `https://`) are not processed
- Single file size limit is 5MB
- Ensure attachment files exist in your Vault
## Auto Sync
The plugin supports automatic syncing that monitors your notes for changes and automatically syncs them to Notion.
@@ -45,46 +112,17 @@ If you change the key name in the settings, update your frontmatter to match.
When auto sync is enabled:
- The plugin monitors markdown files for changes
- **Only files with the auto sync key in frontmatter will be processed**
- Files without the auto sync key are silently skipped - no sync operations or notices
- Files containing internal attachments (local images/PDFs) are skipped - sync them manually
- After you stop editing for the configured delay period, auto sync is triggered
- Files with the `autosync-database` key in frontmatter will be automatically synced
- **First-time upload is supported**: No need to manually sync first - just add the frontmatter key and the plugin will handle the initial upload
- If a file is linked to multiple databases, it will sync to all of them automatically
- After the first sync, a `NotionID-{database}` will be added to the frontmatter for future updates
### Auto Sync Scenarios
#### Scenario A-1: New File Missing Auto Sync Entry
```yaml
---
title: My New Article
tags: [blog, tech]

```
**Behavior:**
- ✅ Detects that the auto sync key is missing
- ✅ Detects no NotionID present (new file)
- ✅ Silently skips - no notice shown
- 📝 **To enable auto sync:** Add `autosync-database: [your-db-abbreviation]` to the frontmatter
#### Scenario A-2: Synced File Missing Auto Sync Entry
```yaml

title: My Article
NotionID-blog: abc123

- ✅ Detects existing NotionID (file was synced before)
- ✅ Shows notice: "⚠️ Auto-sync skipped: Add autosync-database to your frontmatter to specify target databases"
- ✅ No sync operation performed
- 📝 **Action Required:** Add `autosync-database: [blog]` to the frontmatter

1. **自动检测**:同步时,插件会自动扫描笔记内容,识别所有本地附件引用
2. **上传到 Notion**:检测到的附件会通过 Notion File Upload API 上传
3. **链接替换**:上传成功后,笔记中的本地链接会被替换为 Notion 的文件引用
4. **图片显示**:图片会作为 Notion 的图片块显示
5. **文件嵌入**PDF 等非图片文件会作为文件块嵌入
### 注意事项
- 代码块中的附件引用不会被处理
- 外部 URL`http://` 或 `https://`)不会被处理
- 单个文件大小限制为 5MB
- 确保附件文件存在于 Vault 中
