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
