Asynchronous Python client for Python Seafile.

An asynchronous Python client for the Seafile Web API, built for the Home Assistant Seafile integration. It covers the documented Seafile Web API (checked against Seafile 14), plus the system admin API:

Endpoints that only exist in the Professional edition, or that need a server setting, raise SeafilePermissionError or SeafileNotFoundError on servers without them.

pip install aioseafile

import asyncio

from aioseafile import Seafile


async def main() -> None:
    """Run the example."""
    async with Seafile(api_url="https://cloud.example.com") as seafile:
        await seafile.get_auth_token("me@example.com", "password")
        account = await seafile.get_account_info()
        print(f"{account.usage} of {account.quota_total or 'unlimited'} bytes used")
        for library in await seafile.get_libraries():
            print(library.name, library.size)


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

Pass token= instead of calling get_auth_token to reuse a stored token. Admin methods (get_admin_*, create_admin_*, ...) raise SeafilePermissionError for non-admin accounts.

Uploads and downloads are streamed, so large files never have to fit in memory. Use chunk_size to upload in several requests, for example behind a reverse proxy that limits the request size; each chunk is retried on transient errors. Pass on_progress to be told how many bytes were uploaded so far.

async def backup(seafile: Seafile, library_id: str, stream: AsyncIterator[bytes], size: int) -> None:
    """Upload a backup and read it back."""
    await seafile.create_directory(library_id, "/backups")
    await seafile.upload_file(library_id, "/backups", "backup.tar", stream, size=size, chunk_size=50 * 1024 * 1024)
    async for chunk in seafile.download_file(library_id, "/backups/backup.tar"):
        ...

Seafile builds upload and download links from its SERVICE_URL setting, which often differs from the address the client uses. The client rebases these links onto api_url, or onto file_server_url when the file server runs elsewhere.

This is an active open-source project. We are always open to people who want to use the code or contribute to it.

We've set up a separate document for our contribution guidelines.

Thank you for being involved! 😍

The simplest way to begin is by utilizing the Dev Container feature of Visual Studio Code or by opening a CodeSpace directly on GitHub. By clicking the button below you immediately start a Dev Container in Visual Studio Code.

This Python project relies on [UV][poetry] as its dependency manager, providing comprehensive management and control over project dependencies.

Install all packages, including all development requirements:

uv sync --all-groups && prek install

UV creates by default an virtual environment where it installs all necessary pip packages.

This repository uses the pre-commit framework, all changes are linted and tested with each commit. To setup the pre-commit check, run:

uv run prek install

And to run all checks and tests manually, use the following command:

uv run prek run --all-files

It uses pytest as the test framework. To run the tests:

uv run pytest

To update the syrupy snapshot tests:

uv run pytest --snapshot-update
