Overview

The @glue42/core package is the core Glue42 JavaScript module used in applications for sharing data with other Glue42 enabled applications. It can be used by applications hosted in Glue42, a browser or Node.js.

The @glue42/core package is a subset of the @glue42/desktop package which offers tools for more advanced scenarios that require Window Management, Application Management, Activities, Layouts, Channels, etc.

The @glue42/core package contains the following APIs:

• Interop - an Interop API which enables applications to:

  • offer functionality to other applications (JavaScript and native) by registering Interop methods;
  • discover Interop methods and applications which offer Interop methods;
  • invoke Interop methods on the user desktop and across the network;
  • stream and subscribe to real-time data using a Streaming API;

• Shared Contexts - a Shared Contexts API which provides a simple and effective way of sharing data between applications by using shared named data objects;

• Metrics - use the Glue42 Metrics as a way of assessing the life cycle of a certain process (application performance, business process, employee productivity, etc.) by acquiring, recording and monitoring over time specific data about the key performance indicators of the said process;

• Pub/Sub - a basic Pub/Sub API that allows apps to publish/subscribe for messages on a specific topic;

Usage

Running in Glue42

import GlueCore from "@glue42/core";

const initializeGlue42 = async () => {
    // You can pass an optional configuration object to the factory function.
    // If you do not privide configuration, it will be inferred from your application configuration file.
    const glue = await GlueCore();

    // Use the Glue42 APIs.
};

// Handle errors.
initializeGlue42().catch(console.error);

Running in Node.js

Note that your Node.js script should be started by the Glue42 Desktop client in order to receive a gwToken and a gwURL.

import GlueCore from "@glue42/core"

const initializeGlue42 = async () => {

    const config = {
        application: "MyNodeApp",
        gateway: {
            protocolVersion: 3,
            ws: process.env.gwURL
        },
        auth: {
            gatewayToken: process.env.gwToken
        }
    };

    const glue = await GlueCore(config);

    // Use the Glue42 APIs.
};

// Handle errors.
initializeGlue42().catch(console.error);
