Lightweight file storage service

Lightweight File Storage Service (LFSS)

My experiment on a lightweight and high-performance file/object storage service...

Highlights:

• User storage limit and access control.
• Pagination and sorted file listing for vast number of files.
• High performance: high concurrency, near-native speed on stress tests.
• Support range requests, so you can stream large files / resume download.
• WebDAV compatible (NOTE).

It stores small files and metadata in sqlite, large files in the filesystem.
Tested on 2 million files, and it is still fast.

Usage:

pip install lfss
lfss-user add <username> <password>
lfss-serve

By default, the data will be stored in .storage_data. You can change storage directory using the LFSS_DATA environment variable.

I provide a simple client to interact with the service:

lfss-panel --open

Or, you can start a web server at /frontend and open index.html in your browser.

The API usage is simple, just GET, PUT, DELETE to the /<username>/file/url path.
The authentication can be acheived through one of the following methods:

1. Authorization header with the value Bearer sha256(<username><password>).
2. token query parameter with the value sha256(<username><password>).
3. HTTP Basic Authentication with the username and password (If WebDAV is enabled).

You can refer to frontend as an application example, lfss/api/connector.py for more APIs.

By default, the service exposes all files to the public for GET requests, but file-listing is restricted to the user's own files.
Please refer to docs/Permission.md for more details on the permission system.
