If your app needs to receive and send JSON data, but you need to include binary data in it, you can encode it as base64.

## Base64 vs Files { #base64-vs-files }

Consider first if you can use [Request Files](../tutorial/request-files.md) for uploading binary data and [Custom Response - FileResponse](./custom-response.md#fileresponse--fileresponse-) for sending binary data, instead of encoding it in JSON.

            } else if (file.isDirectory()) {
                if (logger.isDebugEnabled()) {
                    logger.debug("Processing directory: directory={}", file.getAbsolutePath());
                }
                final Set<RequestData> requestDataSet = new HashSet<>();
                if (includeContent) {
                    final File[] files = file.listFiles();
                    if (files != null) {

# Static Files - `StaticFiles`

You can use the `StaticFiles` class to serve static files, like JavaScript, CSS, images, etc.

Read more about it in the [FastAPI docs for Static Files](https://fastapi.tiangolo.com/tutorial/static-files/).

You can import it directly from `fastapi.staticfiles`:

```python
from fastapi.staticfiles import StaticFiles
```
