About Elevated CUSS Library

Interact with a CUSS 2.0 Restful API using a simple interface leveraging the asyncronicity of event driven architectures. By using the Elevated CUSS library you will get:

• Simple device interfaces
• Subscribable events for all CUSS states and device status

CUSS (Common Use Self-Service) is a modern Typescript library facilitating application development of Self-Service check-in apps, self-tagging apps and self bag-drop apps.

You can have CUSS 2.0 NOW and run a modern browser entirely without plugins or Java. Finally, your Information Security department will be able to sign off on your CUSS applications.

We have also created typescript angular and react libs facilitating rapid development of CUSS applications.

The library and corresponding app platform also ensure backwards compatibility to legacy 1.X versions of CUSS.

• Typescript libs for Angular and React

The Sandbox

While you are developing your application, you can use the Elevated CUSS Sandbox to test against real platform responses. Watch your application respond correctly to CUSS Events like a paper jam or a required device unavailable.

• CUSS Sandbox

Getting Started

1. Request an access token from the Elevation Software Team.

2. Generate an .npmrc file and add the token to this file.

To install the lib run:

npm install @elevated-libs/cuss2

To begin using the library, you will need to import the library into your project and set up a connection.

import { Cuss2 } from "@elevated-libs/cuss2";

const serviceState: { ref: Cuss2 | any} = { ref: null };
const connect = async (cuss2URL: string, clientId: string, clientSecret: string): Promise<Cuss2 | null> => {
    // Avoid multiple subscriptions
    if (serviceState.ref) {
        return serviceState.ref;
    }
    const ref = await Cuss2.connect(cuss2URL, clientId, clientSecret);
    serviceState.ref = ref;
    return ref;
};

// Connect to cuss2 Platform
const { clientId, clientSecret, platformURL } = platformConfig;
connect(platformURL, clientId, clientSecret)
  .then(checkDevices)
  .catch(connectionFailure);
