@phygrid/hub-client NPM

PhyHub Client

The PhyHubClient is a Node.js class designed to facilitate communication with the PhyHub platform. It provides methods to connect to the PhyHub server, emit events, and handle responses.

Installation

To use the PhyHubClient in your project, you can install it via npm or yarn:

npm install @phygrid/hub-client

yarn add @phygrid/hub-client

Usage

Importing the Client

You can import the PhyHubClient class and the connectPhyClient function in your project as follows:

import { PhyHubClient, connectPhyClient } from '@phygrid/hub-client';

Connecting to PhyHub

To connect to the PhyHub server, use the connectPhyClient function:

const moduleName = 'your-module-name'; // Optional, defaults to Application Instace ID
const dataResidency = 'EU'; // Optional, defaults to 'EU'

const client: PhyHubClient = await connectPhyClient(moduleName, dataResidency);

const client: PhyHubClient = await connectPhyClient();

Methods

isConnected() Check if PhyHub is connected:

const isConnected = client.isConnected();
console.log(`Is connected: ${isConnected}`);

getDeviceStatus() Retrieve the device status:

const deviceStatus = await client.getDeviceStatus();
console.log('Device Status:', deviceStatus);

getScreenInstance() Retrieve the screen instance settings:

const screenInstance = await client.getScreenInstance();
console.log('Screen Instance:', screenInstance);

getEdgeInstance() Retrieve the edge instance settings:

const edgeInstance = await client.getEdgeInstance();
console.log('Edge Instance:', edgeInstance);

getDeviceInstance() Retrieve the device instance:

const deviceInstance = await client.getDeviceInstance();
console.log('Device Instance:', deviceInstance);

getDeviceNetworks() Retrieve the device networks:

const deviceNetworks = await client.getDeviceNetworks();
console.log('Device Networks:', deviceNetworks);

setScreenInstanceReportedProperties(payload) Set the reported properties for the screen instance:

const payload = {
// Your payload here
};

const response = await client.setScreenInstanceReportedProperties(payload);
console.log('Response:', response);

emit(method, ...args) Emit a custom event:

client.emit('yourMethod', { yourData: 'data' }, (response) => {
console.log('Response:', response);
});

emitTo(targetInstance, method, ...args) Emit a custom event to a specific target instance:

client.emitTo('targetInstance', 'yourMethod', { yourData: 'data' }, (response) => {
console.log('Response:', response);
});

Example

Here is a complete example demonstrating how to use the PhyHubClient:

import { connectPhyClient } from '@phygrid/hub-client';

async function main() {
    try {
        const client = await connectPhyClient();

            if (client.isConnected()) {
              console.log('Connected to PhyHub');

              const deviceStatus = await client.getDeviceStatus();
              console.log('Device Status:', deviceStatus);

              const edgeInstance = await client.getEdgeInstance();
              console.log('Edge Instance:', edgeInstance);
            }
    } catch (error) {
    console.error('Error:', error);
    }
}

main();

Signals

The hub-client can be used to initialize and utilize signals efficiently.

Initialization

To initialize and use signals, follow this pattern:

public initializeSignals = async (initParams?: InitSignalPayload) => Promise<SignalsService>

Parameters

Parameter	Type	Description
`initParams`	`InitSignalPayload` (optional)	Optional payload containing initialization data. If not provided, the method fetches necessary data from the device and instance settings.

Example

import { connectPhyClient } from '@phygrid/hub-client';

const initParams = {
  "deviceId": "device-12345",
  "installationId": "install-67890",
  "spaceId": "space-abcdef",
  "tenantId": "tenant-xyz",
  "appVersion": "1.0.0",
  "appId": "com.example.app",
  "environment": "production",
  "dataResidency": "EU",
  "country": "SE",
  "installationVersion": "2.3.4",
  "accessToken": "eyJhbGciOiJIUzI1NiIsInR...",
  "clientUserAgent": "Mozilla/5.0 (Windows NT 10.0; Win64; x64)",
  "ip": "192.168.1.100"
};

const client = await connectPhyClient();
const signals = await client.initializeSignals(initParams);
signals.sendEvent(...);

import { connectPhyClient } from '@phygrid/hub-client';

const client = await connectPhyClient();
const signals = await client.initializeSignals();
signals.sendEvent(...);
