NodeJS Quick Pointers

Here we'll cover quick notes on Node.JS
-------------------------------------------------------

Deployment Alternates:
 - Heroku
 - Nodejitsu (https://www.nodejitsu.com/documentation/)
 - Modulus
 - Joynet
 - AWS

·         ECMA Browser/Server Compatibility Matrix - Kagnax : https://kangax.github.io/compat-table/es6/

·         Passport Authentication (Authentication Middleware for Node.js)- http://passportjs.org/

o   npm install passport --save

o   npm install passport-local --save

o   npm install express-session --save

o   npm install connect-flash --save

·         IIFE – Immediate Invoke Function Expression

·         Configuration Files - https://github.com/lorenwest/node-config/wiki/Configuration-Files

·         Bower: https://bower.io/

·         Package Manager for Web.

·         Bower can manage components that contain HTML, CSS, JavaScript, fonts or even image files.

·         Bower doesn’t concatenate or minify code or do anything else - it just installs the right versions of the packages you need and their dependencies.

·         Bower keeps track of these packages in a manifest file, bower.json

·         Bower is optimized for the front-end. If multiple packages depend on a package - jQuery for example - Bower will download jQuery just once. This is known as a Flat Dependency Graph and it helps reduce page load.

·         npm install bower –g

·         Created .bowerrc file to set Bower directory. (e.g. public/javascripts)

·         bower init to create bower.json file

·         Install Angular (Folders will be auto created under public/javascripts folder)

·         bower install angular –save

·         bower install angular-route –save

·         JWT (JSON Web Token)

·         JSON-based open standard for creating access tokens that assert some number of claims.

·         For example, a server could generate a token that has the claim "logged in as admin" and provide that to a client.

·         npm install jsonwebtoken --save

·         Mongoose

·         npm install mongoose --save

·         Creating Schema

·         Schema Types

·         String

·         Number

·         Built in Validators

·         All Schema Types - required, unique

·         Number - min, max

·         String - enum, match, maxlength, minlength

·         Methods available to use

·         Read

·         find({}) - Find All

·         findOne({username:'abc'}) - Find One

·         findById(1) - Find By ID

·         Query

·         find({}).where('')

·         Update

·         Find the Record

·         Change the property Value

·         Call Save()

·         findOneAndUpdate({username:'abc'},{email:'xyz@test.com'})

·         findByIdAndUpdate(1,{email:'xyz@test.com'})

·         DELETE

·         remove()

·         findOneAndRemove({username:'abc'})

·         findByIdAndRemove({username:'abc'})
