Loopback connector nodes for Node-RED

Loopback is a powerful NodeJS framework to create REST APIs based on declarative model definitions. Node-RED is yet another powerful 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.


## Available Node-RED nodes
Node Description
async-observer Input node which registers an observer on given loopback model and returns to loopback application immediately. This node is suitable to start Node-RED flow asynchronously when any loopback model event occurs.

This node registers an observer by calling Model.observe ('access/before save/after save', function (ctx,next){...})
The entire loopback ctx is copied in Node-RED message context msg.ctx for rest of the Node-RED flow to use. The next() callback is called immediately to return control to loopback application.
sync-observer Input node which registers an observer on given loopback model and starts Node-RED flow. Control is not returned to loopback until sych-observer-end node is called. This node can be used to attach Node-RED flow which can alter the loopback ctx parameters.

This node registers an observer by calling Model.observe ('access/before save/after save', function (ctx,next){...})
The entire loopback ctx is copied in Node-RED message context msg.ctx for rest of the Node-RED flow to use.

IMPORTANT NOTE - Control to the loopback application will not return until sync-observer-end node is called. Any flow that starts with sync-observer must end with sync-observer-end otherwise the loopback application will be stuck forever.
sync-observer-end End sync observer node returns control to loopback application by calling loopback observer’s next() callback.
model-observer Input node which register’s an event listener on any generic javascript event emitted by loopback model.
This node calls Model.on ('event name', function (payload){}) and passes on the payload in Node-RED message context (msg.payload) for rest of the flow to use.
