Bitswan is a framework for building automations and pipelines in Jupyter

Bitswan: A tool for building Pipelines & Automations in Jupyter

You can find example pipelines in the examples directory.

Installation

This library is part of the bitswan suite which is managed by the bitswan workspace cli. You must first install the bitswan workspaces cli before installing and using the bitswan notebooks cli.

$ git clone [e-mail]:bitswan-space/BitSwan.git
$ cd BitSwan
$ curl -LsSf https://astral.sh/uv/install.sh | sh
$ uv venv
$ source .venv/bin/activate
$ uv pip install -e ".[dev]"

Running pipelines

You can run a pipeline with a simple command:

$ bitswan notebook examples/WebForms/main.ipynb

When developing web endpoints it can be helpful to instruct the pipeline to automatically restart if the source code changes.

$ bitswan notebook examples/WebForms/main.ipynb --watch

Running Tests

You can find examples for automatically testing pipelines in the testing examples directory.

Run tests with the --test flag.

$ bitswan notebook examples/Testing/InspectError/main.ipynb --test

Running tests for pipeline Kafka2KafkaPipeline.

    ┌ Testing event:        b'foo'
    └ Outputs:              [b'FOO'] ✔

All tests passed for Kafka2KafkaPipeline.


Running tests for pipeline auto_pipeline_1.

    ┌ Testing event:        b'{"foo":"aaa"}'
    └ Outputs:              [b'{"foo": "A   A   A"}'] ✔

    ┌ Testing event:        b'{"foo":"aab"}'
    │ Probing after-upper.
    └ Outputs:              [b'{"foo": "B   A   A"}'] ✔

    ┌ Testing event:        b'{"foo":"cab"}'
    └ Outputs:              [b'{"foo": "B   A   C"}'] ✘

You can combine --test with --watch to automatically rerun tests whenever the source files change.
