Plugin Manager for SystemLink

⚠️ Preview & Unofficial — This is a community preview project and not a released or supported NI product. It is provided as-is, without warranty of any kind. Features may change or be removed without notice. Use at your own risk.

A curated plugin manager for NI SystemLink custom web apps, notebooks, dashboards, and other extensibility packages. Users can browse, install, upgrade, and remove plugins from both a webapp embedded inside SystemLink and the slcli command-line interface.

How it works

The catalog is hosted as a standard NI Package Manager (nipkg) feed on GitHub:

• Package index — served via GitHub Pages (Packages / Packages.gz)
• Package binaries — distributed as .nipkg files attached to GitHub Releases
• Replication — a SystemLink Feed Service replicates the GitHub Pages feed locally so the webapp can operate within SystemLink's strict Content Security Policy (CSP)

Publishing is curated: all submissions go through a PR-based review process that includes functional testing and a security audit.

Getting started

See CONTRIBUTING.md to submit a plugin, or visit the doc site for an overview.

To develop the webapp locally:

cd webapp
npm install
ng serve

To test release publishing and submission/index checksum safeguards locally:

python -m unittest discover -s scripts/tests -v

These tests use simulated GitHub responses and do not mutate releases. Running submission validation or an index rebuild requires the authenticated gh CLI (GH_TOKEN in CI). See publication policy.
