You can serve static files automatically from a directory using Starlette's Static Files.

Install aiofiles

First you need to install aiofiles:

pip install aiofiles

Use StaticFiles

• Import StaticFiles from Starlette.
• "Mount" it the same way you would mount a Sub-Application.

{!./src/static_files/tutorial001.py!}

Then you could have a directory ./static/ with some files that will be served directly.

Details

The first "/static" refers to the sub-path this "sub-application" will be "mounted" on. So, any path that starts with "/static" will be handled by it.

The directory="static" refers to the name of the directory that contains your static files.

The name="static" gives it a name that can be used internally by FastAPI.

All these parameters can be different than "static", adjust them with the needs and specific details of your own application.
