# node-red-contrib-moleculer
Node Red client for Moleculer Microservices Framework with events, emit, call, request and response support.

* Now Supports v0.14 of Moleculer.
* Added Moleculer Instance to get moleculer client inside a function node.

# Install Instructions

On ~/.node-red folder:
```npm install node-red-contrib-moleculer```

```npm install ioredis``` or ```npm install nats``` // to activate transporter config.

Please test and make feedback.
