1. Introduction to Node js,
Express, Jade, MongoDB

2. Node Js???
Pros
 Server side javascript
 An asynchronous, event-driven framework built on Chrome's V8 JavaScript
engine

3. Node JS???
 Designed for creating easily built and scalable network applications
 Uses a non-blocking, asynchronous architecture
 Lightweight and efficient
 Single threaded
 Active development community for support
 Best suited for data-intensive real-time applications that run across
distributed devices.
Cons
 NOT for CPU intensive applications
 Nested callbacks can reduce code readability

4. NPM – Node Package Manager
 An online repository for the publishing of open-source Node.js projects
 Like Maven or Ruby Gems
 Easy dependency management
 Easy package installation
 Easy version management
 Plethora of node.js libraries and applications are published on npm

5. Express
 Web framework for Node
 Features such as rendering, routing and REST controls.
Jade
 Templating Language for writing HTML templates.
 Produces HTML
 Supports dynamic code
 Supports reusability

6. MongoDB
 NoSQL database
 Does not require a predefined schema as in other RDMS
 Data stored as documents, JSON, key-values
 Schema can be easily changed
 Can be horizontally distributed across servers easily
 Adding or Removing a server is easy
 Open Source
 High scalability
 Big Data ready
 Monk, Mongoskin are some of the tools used to connect to MongoDB

7. Let’s get Started
- Installing Node
 Download the installer from Node.js website
 Run it -> Node Js is installed!
 Open cmd and cd to directory where you want to store your Node Js app
npm install –g express
npm install –g express-generator

8. Lets create an Express Project
Express projectname
 Creates your project with all the necessary packages
 Package.json has the dependencies listed
npm install
 Installs all dependencies to your project
 Npm start – has your project up and running

9. Walk through the demo
