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>
## 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://node-red.github.io/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

# Node-RED
A visual tool for wiring the Internet of Things.
## Quick Start
Check out [INSTALL](INSTALL) for full instructions on getting started.
1. download the zip and unzip, or git clone
2. cd node-red
3. npm install
4. node red.js
5. Open [http://localhost:1880]
## Browser Support
The Node-RED editor runs in the browser. We routinely develop and test using
Chrome and Firefox. We have anecdotal evidence that it works in IE9.
We do not yet support mobile browsers, although that is high on our priority
list.
## Contributing
### Reporting issues
Please raise any bug reports or feature requests on the project's issue
tracker. Be sure to search the list to see if your issue has already
been raised.
### Creating new nodes
The plugin nature of Node-RED means anyone can create a new node to extend
its capabilities. Eventually, the nodes will be npm-installable, but we're not
there yet.
### Pull-Requests
In order for us to accept pull-requests, the contributor must first complete
a Contributor License Agreement (CLA). This clarifies the intellectual
property license granted with any contribution. It is for your protection as a
Contributor as well as the protection of IBM and its customers; it does not
change your rights to use your own Contributions for any other purpose.
## Authors
Node-RED is a creation of the IBM Emerging Technology Services team.
* Nick O'Leary [http://twitter.com/knolleary](@knolleary)

<li>msg.res : <a href="http://expressjs.com/api.html#res">http response</a></li>
</ul>

uses the <a href="http://expressjs.com/api.html#bodyParser">Express bodyParser middleware</a> to parse the content to a JSON object.
</p>
<p>
By default, this expects the body of the request to be url encoded:
<pre>foo=bar&amp;this=that</pre>
</p>
<p>
To send JSON encoded data, the content-type header of the request must be set to
<code>application/json</code>.
</p>
<p>
<b>Note: </b>This node does not send any response to the http request. This must be done within
a subsequent Function node. The <a href="http://expressjs.com/api.html#res">Express response documentation</a>
describes how this should be done.
