node-red-contrib-solace

Node-Red (http://nodered.org) nodes for communicating with a Solace Systems message router (see http://www.solacesystems.com).

#Install

If you haven't already done so, install node-red

$ git clone [email protected]:node-red/node-red.git

Install the pre-requisite modules. From the top-level directory of Node-RED, run:

$ npm install

Then you can install the Solace node-red module

$ npm install node-red-contrib-solace

Edit your settings.js (also in the node-red top level directory) and add the following Solace configuration parameters anywhere after module.exports = {

// Retry time in milliseconds for Solace connections
solaceReconnectTries: 0,
solaceReconnectTime:  15000,

// Solace parameters
solaceLogLevel: 2,   //FATAL=0, ERROR=1, WARN=2, INFO=3, DEBUG=4, TRACE=5
generateSequenceNumber: false,
includeSenderId: false,
generateSendTimestamps: false,
generateReceiveTimestamps: false,
subscriberLocalPriority: 1,
subscriberNetworkPriority: 1,
noLocal: false,

Start node-red as normal

node red -v

Point your browser to http://localhost:1880

You should see orange solace input and output nodes in the pallet on the left side of the screen.

Drag either solace node to the canvas and double click to configure the topic, broker, and message type

Click on the pencil icon to the right of the broker selection box to configure a solace broker connection if one does not already exist.

Publish and subscribe just as you would with the mqtt node with some small differences namely:

A sample flow with wildcard subscriptions is provided in the flows subdirectory

#Usage

You will need access to a Solace Systems message router, which acts as a multi-protocol message broker.

#Test Sandbox

You can try it live on the Solace Systems public message router available at:
