import RunnableCodeBlock from '@site/src/components/RunnableCodeBlock';
import ApiLink from '@site/src/components/ApiLink';
import AddDataToDatasetSource from '!!raw-loader!roa-loader!./add_data_to_dataset.ts';

This example saves data to the default dataset. If the dataset doesn't exist, it will be created.
You can save data to custom datasets by using <ApiLink to="core/class/Dataset#open">`Dataset.open()`</ApiLink>

<RunnableCodeBlock className="language-js" type="cheerio">
	{AddDataToDatasetSource}
</RunnableCodeBlock>

Each item in this dataset will be saved to its own file in the following directory:

```bash
{PROJECT_FOLDER}/storage/datasets/default/
```
