Connectivity to Glue42 Server


A Glue42 Core+ project can connect to a Glue42 Server and use its functionalities.

Glue42 Server is a server-side app that provides data to Glue42 (apps, Layouts, preferences) and allows monitoring and interacting with users running Glue42.

It also includes an Admin UI that helps managing the data stored in the Glue42 Server easier.

For more details about the Glue42 Server, see the Glue42 Server section of the Glue42 Enterprise documentation.

Currently, the @glue42/core-plus library allows:

  • opening a session and authenticating with a Glue42 Server - both basic and token-based authentication mechanisms are supported. You can also provide custom headers to be included in every request;

  • fetching app definitions and Layouts and importing them into the current Glue42 Core+ environment;


Note that this feature is available only under a paid license for Glue42 Core+. For information on purchasing the Glue42 Core+ platform or requesting a trial license, contact us at For more details on how to enable the Glue42 Core+ platform, see the Developers > Glue42 Core+ Platform section.

Use the server property of the configuration object for the @glue42/core-plus library to specify settings for the connection to the Glue42 Server. The following example demonstrates configuring the connection to a Glue42 Server using basic authentication:

import Glue42CorePlus from "@glue42/core-plus";

const config = {
    licenseKey: "my-license-key",
    server: {
        // URL pointing to a Glue42 Server.
        url: "",
        // Basic authentication.
        auth: {
            basic: {
                username: "username",
                password: "password"
        fetchIntervalMS: 10000,
        tokenRefreshIntervalMS: 15000,
        critical: true

const { glue } = await Glue42CorePlus(config);

The server object has the following properties:

Property Type Description
url string Required. URL pointing to a Glue42 Server.
auth object Required. User authentication configuration.
headers object Object containing key/value pairs of headers to be sent with every request.
fetchIntervalMS number Interval in milliseconds at which a new snapshot of app definitions and Layouts will be fetched from the Glue42 Server. Defaults to 60000.
tokenRefreshIntervalMS number Interval in milliseconds at which the session token will be refreshed. Defaults to 3600000.
critical boolean If true, the @glue42/core-plus library will wait for this module to be fully operational before completing its initialization. Defaults to false.

The auth object has the following properties:

Property Type Description
basic object Object with required username and password properties for providing basic authentication.
username string Username for token-based authentication.
token object Object with an optional bearer property holding an authentication token.
