Introduction to Project PhotoGRID Preview 05:11

PhotoGRID is a photo gallery app that we'll build using NodeJS. We will build this app based on technologies that we've learnt so far and we'll take our experience one notch higher by integrating & deploying our app on the Amazon Elastic Compute Cloud (EC2). We will also use a couple of other AWS Services like the S3 Storage Service, Elastic IP & Cloudfront.

IMPORTANT : Before you Begin Preview 2 pages

This document should be read properly to avoid potential problems with this chapter.

Examining the User Interface & Getting Started Preview 06:41

As in the ChatCAT example, the User Interface files have been provided. We'll examine the user interface in this video.

Creating the Express App & Setting up Socket.io Preview 08:10

In this video, we'll download Express 4.0 - one of the most popular frameworks for making NodeJS apps. Once done, we'll create a basic scaffold for a working Express app. We'll also install SocketIO & Hogan-Express modules as well.

Creating the Routes.js module Preview 01:46

In this video, we'll create a Routes module like how we created in the ChatCAT example.

Creating Configuration Files Preview 03:02

In this video we'll create configuration files and a module to manage development and production environments.

Amazon Web Services | Signing Up & Creating an S3 Bucket Preview 05:36

Amazon is the global leader in Cloud Computing Services. In this video, we'll signup for an account on Amazon Web Services and we'll begin by provisioning an S3 (Simple Storage Service) Bucket to store all the photos that the user uploads via PhotoGRID.

Amazon Web Services | Setting up a Bucket Policy Preview 04:53

Access to an Amazon S3 Bucket depends on a bucket policy, without which users would be unable to access files. In this video we'll create a bucket policy.

Amazon Web Services | Setting up Knox Preview 05:04

To enable our PhotoGRID app to interact with the Amazon S3 Bucket, we'll use the KnoxJS module. In this video we'll download and setup the KnoxJS module.

Setting up the Upload Button Handler & AJAX Preview 14:48

In this video, we'll prep our front end to transfer files using a custom built AJAX function. Instead of using jQuery or similar libraries, we'll cook our own AJAX function.

Setting up Formidable for Receiving the files Preview 13:41

Once the Javascript on the front end UI sends the file using AJAX, we'll use the Formidable module to receive the files within the NodeJS app. In this video we'll download and setup Formidable so it is able to receive files.

Setting up GraphicsMagick Library + gm for Nodejs for resizing images Preview 05:16

Before we put uploaded images into the S3 bucket, we will resize them down to a width of 300 pixels. To achieve that, we'll use the GraphicsMagick Image Processing Library along with the gm module in NodeJS which will interact with GraphicsMagick to resize the images.

Uploading resized images to the S3 using Knox Preview 05:13

In this video we'll write code which uploads files after they've been resized using GraphicsMagick to the S3 bucket using the Knox module.

Storing the file name and votes in MongoDB on MongoLab Preview 12:05

In this video, we'll create a MongoDB database on MongoLab and we'll store the name of our file and the initial vote count in a collection. Additionally we'll also delete the image file as locally stored on the server during the resizing process.

Getting images into the Photogrid gallery Preview 15:36

As Photos are uploaded, the gallery portion of our PhotoGRID website should also update to reflect all images.

Amazon Web Services | Setting up CloudFront Distribution Preview 04:19

Since we're serving image files from our S3 bucket onto our PhotoGRID gallery, we need to optimize S3 for delivery. This can be done by using Amazon's CloudFront service which turns our S3 bucket into a Content Delivery Network (CDN) that is optimized for delivery.

Creating the Vote Up Functionality & Final Testing Preview 10:50

PhotoGRID also incorporates a vote-up functionality that lets users upvote images that they like. I've kept the functionality very simple and as a matter of fact it allows you to keep clicking to increase the vote count which is unlike how it would be in a production case scenario. However, this should whet your appetite enough to build a more practical version of the vote-up functionality. We'll also test our app so its ready for deployment.

Amazon Web Services | Creating an Elastic Compute Cloud (EC2) Instance Preview 05:58

An Amazon Elastic Compute Cloud Instance (EC2) is a server in the cloud that you can easily instantiate and setup. It comes with an OS of your choice with full root access to let you install, and setup virtually anything. In this video, we'll spin up our EC2 instance in preparation for deploying our NodeJS App.

Amazon Web Services | Installing NodeJS on EC2 Preview 04:38

To run NodeJS apps, we need to install NodeJS on our EC2 instance. This video shows you how.

Amazon Web Services | Creating an Elastic IP for your EC2 Instance Preview 03:11

So far we've been accessing the EC2 instance using a public DNS which can change if the server is restarted. To ensure we're able to access the server, we'll setup an Elastic IP which binds our server to a fixed IP address. This ensures that even if we restart our EC2 instance, we would still be able to access the server using the fixed IP provided to us by Elastic IP.

Amazon Web Services | Installing the Photogrid App on the EC2 Instance Preview 06:55

And the big moment arrives when we finally deploy the PhotoGRID app on our EC2 instance !

Amazon Web Services | Security Group, Ports & Port Forwarding Preview 14:07

Before we can access the NodeJS app, we need to setup our security group, open ports and ensure that Port 80 (HTTP) forwards to our PhotoGrid NodeJS App typically running on Port 3000.

Important :: It should be noted that practically speaking, we should use NGINX Web Server as a front facing server that routes requests from Port 80 to Port 3000 on the NodeJS app through reverse proxying requests. This is demonstrated exclusively in the next section in this course. For now, I've kept the deployment easy to understand by simply forwarding Port 80 to Port 3000.

Amazon Web Services | Ensuring the Photogrid app runs automatically Preview 07:17

Imagine a situation where your EC2 instance reboots. This would mean that the NodeJS app would not come back online since so far we've been launching it manually from the terminal. We'll correct this in this video by making sure the app runs automatically when the server starts up.

What are we talking about ? Preview 03:38

The Awesome Cloud9 IDE Preview 07:12

Digital Ocean has become the third fastest growing Cloud Hosting provider in the world and is competing directly with the biggies such as Amazon. Digital Ocean has been designed with developers in mind and gets you up and running in no time with no complexity involved at all.

Installing Nginx Preview 01:38

NGINX is a super fast Web Server, Proxy Server and a Load Balancer, all rolled into one. By placing NGINX infront of your NodeJS apps, you can deliver static assets such as images, css files and javascript files directly without routing them through the Node app which negatively affects performance. In this video, we'll install NGINX on our Digital Ocean server instance (Droplet)

Nginx as a Proxy Server for NodeJS Preview 07:55

By using NGINX as a reverse proxy server for our NodeJS app, we get optimum performance because NGINX takes over serving static files including caching.

Uploading and Reconfiguring ChatCAT to work with Nginx Preview 06:02

In this video we'll install our good old ChatCat on the Digital Ocean Server using NGINX as a reverse proxy. Download the accompanying archive that contains a slightly modified ChatCAT App that is ready to be installed on the Digital Ocean instance.

Load Balancing with NGINX Preview 03:59

A Load Balancer distributes the incoming user traffic over a cluster of servers so as not to overload a single server instance. NGINX is a terrific load balancer that is super easy to configure. In this video, I'll show you to how to configure NGINX when using it as a Load Balancer.

Introduction to Enterprise Integration Preview 10:56

Enterprise integration refers to the process of getting software across a gamut of platforms and servers to talk and share data with each other.
