A small, prototypical zarrita-like Python Zarr implementation on top of zarrs.
Project description
zarrista
A low-level Zarr API for Python, inspired by zarrita.js, powered from Rust by Zarrs. Serving up Zarr chunks like your favorite barista!
This has been minimally vibe-coded: mostly but not fully written by hand. Some areas were prototyped with Claude.
Development
Requires a Rust toolchain and Python 3.11+. We use uv and maturin.
# Create a dev environment and install the dev dependencies
uv sync --no-install-package zarrista
# Build the Rust extension and install it into the environment (debug build)
uv run --no-project maturin develop --uv
# Or, in release mode:
uv run --no-project maturin develop --uv --release
# Run the tests
uv run --no-project pytest
The --no-project is annoying but unavoidable in our current setup. Otherwise uv will try to build the rust library in release mode, as a dependency of the project before reaching uv sync or uv run.
