Node-RED Install

Install node.js

You can get the latest version from http://nodejs.org/download/.

Or, you may want to use a version from your operating system's package manager: https://github.com/joyent/node/wiki/Installing-Node.js-via-package-manager

Get Node-RED

Clone the repository from GitHub:

$ git clone git@github.com:node-red/node-red.git

Install the pre-requisite modules

From the top-level directory of Node-RED, run:

$ npm install

This will install the core pre-requisite modules.

Run Node-RED

From the top-level directory, run:

$ node red.js

You can then access Node-RED at http://localhost:1880.

Online documentation is available at http://nodered.org/docs.

Installing individual node dependencies

When Node-RED starts, it attempts to load the nodes from the nodes/ directory. Each will have its own set of dependencies that will need to be installed before the node is available in the palette.

To help identify the dependencies, Node-RED logs any modules it fails to find for a particular node. You don't have to install these unless you want or need that node to appear.

Alternatively, a node's .js file can be examined to identify the modules it explicitly requires. For example, the Twitter node is defined in nodes/social/27-twitter.js and contains:

var RED = require("../../red/red");
var ntwitter = require('ntwitter');
var OAuth= require('oauth').OAuth;

Of these, ntwitter and oauth are neither built-in modules nor ones provided by Node-RED itself. They can subsequently be installed by running:

$ npm install ntwitter oauth
