just-bash-bundled-runtime 22.23.0

First-party bundled Node.js runtime provider for just-py-bash

just-bash-bundled-runtime

just-bash-bundled-runtime is the first-party bundled Node.js runtime provider for just-py-bash.

Most users should install it indirectly via the main package extra:

uv add 'just-py-bash[node]'

That gives just-py-bash a bundled node binary to use when no system Node.js is available on PATH.

What it provides

• a platform-specific wheel containing a vendored Node.js runtime
• helper functions to locate the bundled executable from Python
• runtime metadata including the bundled Node version, platform, archive URL, and SHA-256
• runtime payloads built from official Node.js release archives and verified against upstream SHASUMS256.txt

Install

Requires Python 3.11+

Use case	Command
Recommended: install through the main package extra	uv add 'just-py-bash[node]'
Install the runtime package directly	uv add just-bash-bundled-runtime
Install from a local checkout	uv add ./just_bash_bundled_runtime

Install name: just-bash-bundled-runtime
Import name: just_bash_bundled_runtime

Quick start

import subprocess

from just_bash_bundled_runtime import get_node_command, get_runtime_metadata

metadata = get_runtime_metadata()
print(metadata["node_version"])
print(metadata["platform"])

completed = subprocess.run(
    [*get_node_command(), "--version"],
    check=True,
    capture_output=True,
    text=True,
)
print(completed.stdout.strip())

Public helpers

The package exports:

• get_node_command()
• get_node_executable()
• get_runtime_metadata()
• get_runtime_root()

How just-py-bash uses it

When the companion package is installed, just-py-bash resolves Node.js in this order:

1. node_command= passed to Bash(...) or AsyncBash(...)
2. JUST_BASH_NODE
3. the bundled runtime from just-bash-bundled-runtime
4. a system node on PATH

That means most consumers only need to install just-py-bash[node]; the main package handles the runtime discovery automatically.

Development

Populate the local runtime payload:

python just_bash_bundled_runtime/tools/vendor_runtime.py

Build a wheel from the repository root:

uv build just_bash_bundled_runtime --wheel --out-dir dist-node

Versioning

Package versioning for just-bash-bundled-runtime is intentionally independent from just-py-bash and tracks the bundled Node.js version.

See VERSIONING.md for the runtime package version policy and release tag semantics.
