Installation

nexSys4 runs in Achaea's Nexus web client and expects the Nexus runtime, EventStream, and GMCP to be available.

Install the Nexus package​

The release includes nexSys4.nxs, a Nexus package file. Import it through the Nexus package/reflex interface, then reload the client if its package groups do not appear immediately.

The npm package also contains the prebuilt runtime at dist/nexsys4.min.js. This form is intended for scripted installation and integration work:

import("https://unpkg.com/nexsys4/dist/nexsys4.min.js").then(() => {
  nexusclient
    .packages()
    .get("nexSys4")
    .items.filter((item) => item.type === "group")
    .forEach((group) => {
      group.enabled = true;
    });

  nexSys.bootstrapNexus();
});

Importing the JavaScript bundle exposes the bootstrap function; it does not start the live runtime until bootstrapNexus() is called.

Verify the runtime​

After startup, evaluate this in the Nexus developer console:

Object.keys(nexSys);
// ["state", "api", "events"]

Then open the configuration dialog:

nexSys.api.ui.openConfig();

Continue with the Quickstart.
