red-loopback

red-loopback glues LoopBack & Node-Red together and provides features on top of it.

LoopBack is great as a node framework. It is built on top of Express JS.
Node-Red gives visual flow based interface.And its great for wiring together nodes (it has tons of ready to use nodes in its catalogue)

Usecases

Theratically, you can write most of your business logic code in Node-RED. But idea is to use flow based approach for side-effects like notifications, alerts, scheduler jobs, dashboard services etc.

Some of the cases for a hypothatical project management system

• When a task is assigned to a user, he should get email/sms notification.
• When a task is added, subscribing creator & assigner to that task.
• When a task is updated, sending update notification to subscribed users of that task.
• Generating weekly summary & emailing all the users of each project
• Dashboard services & Dashboard UI as well
