dx
Efficient display and blob-store uploads for Python kernels running under nteract.
dx lets a Python kernel push bytes directly to the nteract daemon's blob store via a dedicated Jupyter comm, bypassing the IOPub "raw bytes" anti-pattern. Display bundles carry a tiny reference MIME (application/vnd.nteract.blob-ref+json) instead of megabytes of parquet/image/video data.
Usage
import dx
dx.install()
import pandas as pd
df = pd.read_parquet("big.parquet")
df # rendered via the sift parquet renderer from a blob reference
Low-level:
ref = dx.put(open("image.png", "rb").read(), content_type="image/png")
dx.display_blob_ref(ref, content_type="image/png")
See docs/superpowers/specs/2026-04-13-nteract-dx-design.md for the protocol.
In vanilla Jupyter or plain python
dx.install() is a no-op when no nteract runtime agent is reachable. dx.display(df) falls back to raw-bytes display, and dx.put(...) raises DxNoAgentError. The library is safe to import anywhere.
