[Loopback] ( https://github.com/strongloop/loopback) is a powerful NodeJS framework to create REST APIs based on declarative model definitions. [Node-RED] ( https://github.com/node-red/node-red) is yet another porwerful tool to wire together APIs and online services.

This project provides a set of custom Node-RED nodes which can be used to integrate Node-RED with any loopback application.

This integration greatly enhances the existing capabilities of loopback application by allowing to observe the application in Node-RED and inject code at runtime without touching the original application.


It is required to run Node-RED from within the loopback application. This project provides node-red.js module which can be used either in loopback boot script or in server.js to start Node-RED server. Refer to installation section for more details.


Install this node module

npm install git+https://github.com/EdgeVerve/loopback-connector-nodes-for-Node-RED.git 


npm install git+git@github.com:EdgeVerve/loopback-connector-nodes-for-Node-RED.git

Start Node-RED Server from loopback application

In your loopback application simply add a new boot script with following code in it

var nodeRed = require("loopback-connector-nodes-for-Node-RED");

module.exports = function(server, callback) {
    nodeRed.start({port:22081}, function() {

Upon the application startup, Node-RED server will be available to access on http://localhost:22081/red.

You can also specify following options while starting Node-RED

var options = {
    port: <port number on which Node-RED server to be started>,
    settings: {
        httpAdminRoot: ...,
        httpNodeRoot: ...,
        userDir: ...,
        nodesDir: ...,
        flowFile: ...,
// Please see default settings.js file in node_modules/node-red for other options for settings.
