Xpublish
Publish Xarray Datasets and DataTrees to the web
A quick example
Serverside: Publish an Xarray Dataset or DataTree through a REST API
ds.rest.serve(host="0.0.0.0", port=9000)
# or, for a hierarchical DataTree, the API is identical:
dt.rest.serve(host="0.0.0.0", port=9000)
Client-side: Connect to a published dataset
The published datasets can be accessed from various kinds of client applications, including any HTTP client. To explore the available endpoints, open http://0.0.0.0:9000/docs in a browser.
Why?
Xpublish lets you serve/share/publish Xarray Datasets and DataTrees via a web application.
The data and/or metadata can be exposed in various forms through pluggable REST API endpoints. Hierarchical data is supported natively — bare Datasets are wrapped in a single-node DataTree internally so the same routes, accessors, and plugins work whether you're serving a flat dataset or a deeply nested tree. Efficient, on-demand delivery of large datasets may be enabled with Dask on the server-side.
Xpublish's plugin ecosystem has capabilities including:
- publish on-demand or derived data products
- turning xarray objects into streaming services (e.g. OPeNDAP)
- Zarr-compatible access via xpublish-zarr
How?
Under the hood, Xpublish is using a web app (FastAPI) that is exposing a REST-like API with builtin and/or user-defined endpoints. Additional endpoints can be added by installing or writing plugins.
