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
