+> Igloo is a library of components built with [electrolyte][electrolyte] to be used as building blocks for an app.

+
+
+## Install
+
+**Please use [eskimo][eskimo] which has igloo built-in.**
+
+However you can use igloo in your own project by installing it.
+
+```bash
+npm install -s igloo
+```
+
+
+## Usage
+
+You will need to first `require('igloo')`, define a "config" component, and then use `electrolyte`'s `IoC.loader` method to load `igloo`'s components ([listed below][#components]).
+
+> **Note that `igloo` requires you to have defined a "config" component (since `igloo`'s "setting" component requires it as a dependency).  For example, [Eskimo][eskimo] defines a "config" component [here][eskimo-default-config].**
+
+```js
+// boot/config.js
+
+exports = module.exports = function() {
+  return {
+    defaults: {
+      logger: {
+        console: true,
+        requests: true,
+        mongo: false,
+        file: false,
+        hipchat: false
+      },
+      output: {
+        handleExceptions: true,
+        colorize: true,
+        prettyPrint: false
+      }
+    },
+    development: {
+      server: {
+        port: 3000
+      }
+    },
+    production: {
+      server: {
+        port: 3080
+      },
+      logger: {
+        requests: false
+      },
+      output: {
+        colorize: false,
+        prettyPrint: false
+      }
+    }
+  }
+}
+
+exports['@singleton'] = true
+
+```
+
+You can have a `boot/local.js` with local settings if you need something unversioned (and load it when the environment is `development` — default).
+
+```js
+// boot/local.js
+
+var path = require('path')
+var uploadsDir = path.join(__dirname, '..', 'uploads')
+var maxAge = 30 * 24 * 60 * 60 * 1000
+
+exports = module.exports = function() {
+
+  return {
+    uploadsDir: uploadsDir,
+    server: {
+      host: '0.0.0.0',
+      env: 'local',
+      port: 3003,
+    },
+    mongo: {
+      dbname: 'igloo-local',
+    },
+    redis: {
+      prefix: 'igloo-local',
+      maxAge: maxAge
+    }
+
+  }
+
+}
+
+exports['@singleton'] = true
+```
+
+
+```js
+// app.js
+
+var IoC = require('electrolyte')
+var igloo = require('igloo')
+var path = require('path')
+var express = require('express')
+var winstonRequestLogger = require('winston-request-logger')
+
+IoC.loader(IoC.node(path.join(__dirname, 'boot')))
+IoC.loader('igloo', igloo)
+
+// logger component
+var logger = IoC.create('igloo/logger')
+logger.info('Hello world')
+
+// settings component
+var settings = IoC.create('igloo/settings')
+
+// basic server
+
+var app = express()
+
+// winston request logger before everything else
+// but only if it was enabled in settings
+if (settings.logger.requests)
+  app.use(winstonRequestLogger.create(logger))
+
+app.get('/', function(req, res, next) {
+  res.send("It's cold outside, but warm in the igloo")
+})
+
+app.listen(settings.server.port, function() {
+  logger.info('Server started on port %d', settings.server.port)
+})

+
+### email
+
+> Returns a function which accepts templateName, locals, headers, transport, and callback arguments.  This component uses
+
+[View source](lib/boot/email.js)
+
+```js
+// example - email
+
+// TODO: finish this!
+
+// mention that transport defaults to settings.email.transport
+
+// mention that headers inherits settings.email.headers
+
+// but only if you don't set `headers.useDefaults: false`
+
+// note that is also uses `settings.email.templates` object
+// which can have `dir` string and `options` object for node email-templates pkg
+
+// also document about having `transport` of `settings.email.transport` be an
+// actual transporter already pre-created (possibly with plugins like html-to-text)
+
+```
+
+### error-handler
+
+> Returns [Express][express] route middleware for error handling.
+
+[View source](lib/boot/error-handler.js)
+
+```js
+// example - error handler
+
+var _ = require('underscore')
+var errorHandler = IoC.create('igloo/error-handler')
+
+app.post('/user', createUser, errorHandler)
+
+// you could also do:
+// app.post('/user', createUser)
+// app.use(errorHandler)
+// but make sure that `app.use(errorHandler)`
+// is the very last route middleware to be `use`'d
+
+function createUser(req, res, next) {
+
+  if (!_.isString(req.body.name))
+    return next({
+      param: 'name',
+      message: 'User name is missing'
+    })
+
+  // ... create a user in your db
+  res.send('You successfully created a user')
+
+}
+
+```
+
+
+### knex
+
+> Returns a [Knex][knex] SQL database connection using `settings.knex`.
+
+[View source](lib/boot/knex.js)
+
+```js
+// example - knex
+
+var knex = IoC.create('igloo/knex')
+
+app.get('/users', function(req, res, next) {
+  knex
+    .raw('SELECT * FROM USERS LIMIT 10')
+    .exec(function(err, results) {
+      if (err) return next(err)
+      res.send(results)
+    })
+})
+
+```
+
+
+### logger
+
+> Returns a [Winston][winston] logger object with pre-configured transports using `settings.logger` and `settings.output`.
+
+[View source](lib/boot/logger.js)
+
+```js
+// example - logger
+
+var logger = IoC.create('igloo/logger')
+
+logger.info('Hello world')
+
+```
+
+
+### mongo
+
+> Returns a [MongoDB][mongodb] NoSQL connection using `settings.logger`, `settings.output`, and `settings.mongo` and [Mongoose][mongoose] ORM.
+
+> TODO: Should we rename this to `igloo/mongoose`?
+
+[View source](lib/boot/mongo.js)
+
+```js
+// example - mongo
+
+var validator = require('validator')
+var mongoose = IoC.create('igloo/mongo')
+
+var User = new mongoose.Schema({
+  email: {
+    type: String,
+    required: true,
+    unique: true,
+    validate: validator.isEmail
+  }
+})
+
+mongoose.model('User', User)
+
+```
+
+
+### mongoose-plugin
+
+> Returns a [Mongoose][mongoose] plugin helper for common schema additions.
+
+[View source](lib/boot/mongoose-plugin.js)
+
+```js
+// example - mongoose plugin
+
+var validator = require('validator')
+var mongoose = IoC.create('igloo/mongo')
+var mongoosePlugin = IoC.create('igloo/mongoose-plugin')
+
+var User = new mongoose.Schema({
+  email: {
+    type: String,
+    required: true,
+    unique: true,
+    validate: validator.isEmail
+  }
+})
+
+User.plugin(mongoosePlugin)
+
+mongoose.model('User', User)
+
+```
+
+
+### server
+
+> Returns a function which accepts a callback argument (currently no `err` argument is returned when this callback function is executed).  This component starts either a [cluster][cluster] (with one thread per CPU) or a simple single-threaded instance using `app.listen`.  This should be used with `app.phase` using [bootable][bootable], since bootable's "phases" (`app.phase`) method accepts this callback function as a standard argument when defining a "phase" (read more about bootable to understand this please).  This component uses `settings.logger`, `settings.output`, and `settings.server`.
+
+[View source](lib/boot/server.js)
+
+```js
+// example - server
+
+var bootable = require('bootable')
+var express = require('express')
+
+var app = bootable(express())
+
+var server = IoC.create('igloo/server')
+var logger = IoC.create('igloo/logger')
+
+// this should always be the last phase
+app.phase(server)
+
+app.boot(function(err) {
+
+  if (err) {
+    logger.error(err.message)
+    if (settings.showStack)
+      logger.error(err.stack)
+    process.exit(-1)
+    return
+  }
+
+  logger.info('app booted')
+
+})
+
+```
+
+
+### sessions
+
+> Returns a [Redis][redis] connection using `settings.logger`, `settings.output`, and `settings.redis` with [express-session][express-session] and [connect-redis][connect-redis].
+
+[View source](lib/boot/sessions.js)
+
+```js
+// example - sessions
+
+var session = require('express-session')
+var express = require('express')
+
+var app = express()
+
+var sessions = IoC.create('igloo/sessions')
+var settings = IoC.create('igloo/settings')
+
+// add req.session cookie support
+settings.session.store = sessions
+app.use(session(settings.session))
+
+```
+
+
+### settings
+
+> Returns a settings object using a "config" component defined and loaded by [electrolyte][electrolyte] in a location such as "boot/config" (see initial example at the top of this Readme).
+
+For a full config example file, see [Eskimo's default config][eskimo-default-config].
+
+[View source](lib/boot/settings.js)
+
+
+### update-notifier
+
+> Returns nothing, as it is used for notifying an app of module updates using [update-notifier][update-notifier].
+
+> TODO: Look into why this isn't working per <https://github.com/yeoman/update-notifier/issues/25>
+
+[View source](lib/boot/update-notifier.js)
