storix 0.4.4

One unix-flavored filesystem API over any storage: local disk, in-memory,
Azure, S3, GCS. Python-first, sync and async, sandboxable, fully typed.

Documentation: storix.mghalix.com

Storix puts one unix filesystem interface in front of every storage backend, so you work with cloud storage the way you already work with local files: ls, cd, cat, mkdir, mv, rm. The backend can be your disk, an in-memory store for tests, or Azure / S3 / GCS in production, behind one small, fully typed API, sync or async. Swap the backend, keep the code.

It is not a plumbing competitor to the cloud SDKs. It is the ergonomic layer over them, the way FastAPI is a layer over the web rather than a new web server.

Install

uv add storix            # local filesystem + in-memory
uv add "storix[azure]"   # + all of Azure Storage (ADLS Gen2 + Blob)
uv add "storix[s3]"      # + Amazon S3 (r2 / minio alias it)
uv add "storix[gcs]"     # + Google Cloud Storage
uv add "storix[cli]"     # + the sx command-line interface
uv add "storix[all]"     # all optional features

Quick look

from storix import Storix
from storix.backends import LocalBackend

fs = Storix(LocalBackend('~/storix-data'))  # '/' is anchored at ~/storix-data

fs.mkdir('/docs')
fs.echo('hello, storix!', '/docs/readme.txt')
print(fs.cat('/docs/readme.txt'))       # b'hello, storix!'

fs.cd('/docs')                          # a session has a cwd, like a shell
fs.mkdir('/archive')
fs.mv('readme.txt', '/archive')         # the last argument is the destination

Async is the same API under storix.aio, generated from the sync source so the two never drift:

from storix.aio import get_storage

async with get_storage('azure') as fs:
    await fs.echo(b'...', '/report.csv')
    print(await fs.url('/report.csv', expires_in=600))   # presigned SAS link

The sx shell

The cli extra puts the same core behind a command line, one-shot or interactive:

uv add "storix[cli]"

sx                                    # interactive shell (tab completes paths)
sx -p azure ls -l /media              # or a single command, any provider
sx upload ./video.mp4 /media/         # host -> provider, with a progress bar

Listings carry Nerd Font icons and coreutils-style sizes (165M); transfers render progress through the ObservabilityLayer. Preferences and an always-on layer stack persist in ~/.config/storix/config.toml, a project storix.toml, or pyproject.toml:

[tool.storix.cli]
icons = true
provider = 'azure'                          # what sx opens by default
layers = [{ name = "cache", ttl = 300 }]    # every session, read-through

Highlights

• Unix semantics, everywhere. ls/cd/cat/du/mv with a real session and cwd, identical across local, memory, and cloud.
• Python-first and streaming. echo takes bytes, str, an iterator, or an async iterator, so large files move through bounded memory instead of loading whole.
• Composable layers. Sandbox a session (escape-proof chroot), add a read-through cache, emit transfer progress, or backfill capabilities, all as middleware that wraps any backend.
• Sync and async, one API, generated from a single source and proven by one conformance suite across every backend.
• Typed and safe. Fully typed and py.typed. Every failure raises a typed error, and a sandbox cannot be escaped, not even by the code inside it.

Backends

Third-party backends implement the small StorageBackend port and register via register_backend(). See Write a custom backend.

Migrating from 0.1.x

0.2.0 was a ground-up rework (hexagonal core, generated sync flavor, layers, capabilities). See the migration table in release-notes.md.
