# HF Spaces

The HF Spaces resource mounts a [Hugging Face Space](https://huggingface.co/spaces)
repo (app code, README, config, requirements) at some prefix such as `/s/`.

For credential setup, see [HF Spaces Setup](/home/setup/hf_spaces).

## Install

```bash theme={null}
uv add "mirage-ai[hf]"
```

## Config

```python theme={null}
import os

from mirage import MountMode, Workspace
from mirage.resource.hf_spaces import HfSpacesConfig, HfSpacesResource

config = HfSpacesConfig(
    repo_id=os.environ["HF_SPACE_REPO"],   # "namespace/space-name"
    token=os.environ.get("HF_TOKEN"),
    # Optional:
    # endpoint="https://huggingface.co",
    # revision="main",
)
resource = HfSpacesResource(config)
ws = Workspace({"/s": resource}, mode=MountMode.READ)
```

## Filesystem Layout

For example, `HuggingFaceBio/carbon-demo` mounted at `/s/` might expose:

```text theme={null}
/s/
  README.md
  app.py
  requirements.txt
  Dockerfile
```

## Example

```python theme={null}
import asyncio

from mirage import MountMode, Workspace
from mirage.resource.hf_spaces import HfSpacesConfig, HfSpacesResource


async def main() -> None:
    resource = HfSpacesResource(
        HfSpacesConfig(repo_id="HuggingFaceBio/carbon-demo"))
    ws = Workspace({"/s": resource}, mode=MountMode.READ)

    r = await ws.execute("ls /s/")
    print(await r.stdout_str())

    r = await ws.execute("cat /s/README.md | head -n 20")
    print(await r.stdout_str())

    r = await ws.execute("grep -l import /s/*.py 2>/dev/null")
    print(await r.stdout_str())


if __name__ == "__main__":
    asyncio.run(main())
```

## Shell Commands

Same set as [HF Buckets](/python/resource/hf_buckets#shell-commands).

## Use Cases

* **Space introspection**: Browse an app's structure, requirements, and
  config before forking/cloning
* **App code review**: `grep` / `find` across a Space's Python without
  cloning the repo
