Node red function node with capability to install packages from npm

node-red-contrib-function-npm

Node red function node with capability to install and use packages from npm

Compatability

node-red version > 1.0

Install

From your node-red directory

npm install node-red-contrib-function-npm

Usage

The function-npm node behaves like a normal function node, with the exception of allowing the use of npm modules within the script inside the block. It scans the script for any require statements and downloads the modules specified in the require statements. The module is automatically cleaned from the disk when the node-red process closes.

//syntax to install a specific version
var lowerCase = require('lower-case@1.1.3')

//if no version specified the latest version is installed
var upperCase = require('upper-case');

msg.payload = {             
    upper: upperCase('Hello World'),
    lower: lowerCase('Hello World')
} ;
return msg;
