# saveCurrentNote

> Save the currently opened note file.

When operating on the currently opened note, changes are typically written to an in-memory cache and are not persisted to the file immediately.
If you call file-related APIs without saving (e.g. [`replaceElements`](/en/api-reference/supernote-plugin/plugin-file-api/replace-trails),
[`insertElements`](/en/api-reference/supernote-plugin/plugin-file-api/insert-trails)、
[`modifyElements`](/en/api-reference/supernote-plugin/plugin-file-api/modify-trails) etc.),
the data state may become inconsistent. It is recommended to call `saveCurrentNote` first to persist cached data to the file, and then perform file-level read/write operations.

```ts theme={null}
static saveCurrentNote(): Promise<APIResponse<boolean>>;
```

**Returns**

* [`APIResponse<boolean>`](/en/api-reference/supernote-plugin/types/api-response):
  `result === true` indicates saving the note file succeeded

## Example

```ts wrap theme={null}
import { PluginNoteAPI } from 'sn-plugin-lib';

/**
 * Example: save the current note.
 */
export async function exampleSaveCurrentNote() {
 const res = await PluginNoteAPI.saveCurrentNote();
 if (!res.success) {
 throw new Error(res.error?.message ?? 'saveCurrentNote call failed');
 }
 return res.result;
}
```
