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
|
|
|
