In random order:

Install Bootstrap

Create website for project on techiemouse.com domain  

Read image data from folder

Install mongo

Create mongo  

Save image data in mongo

Calculate statistics, analyse data

Show data on page using graphs

Learn/use ejs

Read exif data on client side  -> spike and prototype with APIs found

I definitely have a clear idea of what I want. And unlike the other agile projects there is no team there is no product manager, there is no scrum, there is no customer. So how will it work? Do I apply the rules or go with the flow? Or do I go towards a more organised approach?! Waterfall?!

One: Set-up the gitHub repository, and here it is: ExifDataAnalysis 

Two:  Clone the repository and start installing the needed technologies. Most of the package managers and languages I needed were already installed previously. I used: homebrew and nvm to install npm and node.

Three: Creating the dependencies file, also known as package.json. This was initiated using the basic: npm init.

This is where I encountered a first issue: npm init wasn’t recognised as a command in the project folder. To get this fixed:

I checked node version, which was the correct one: 0.10.30

To unblock npm (that was actually installed) I run the command: nvm install 0.10.30 which responded with: v0.10.30 is already installed.

This actually corrected the error and I could run the command and create the package.json. (a weird little bug)

Four: Installing the node framework. I chose express as it’s what we’re using on our work system. But I did have a cheeky look at: Restify, Hapi;

At work we’re allowed and encouraged to start-up Friday projects. About a month ago I moved teams starting from scratch with new people new project, new system, new programming languages and technologies. All the Android knowledge gathered and used in my previous team was no longer needed anymore. This has been a scary and exciting experience.

Now I’m starting to learn more about servers, web and databases and the most amazing thing is: it’s reminds me tremendously of my initial dissertation goal (the one I didn’t manage to get to): big data analysis and user friendly graphs and tables (Can’t say more than that I’m afraid).

Let’s go back to the actual subject of this blog post: Friday projects. I’m starting one! To learn some of the new technologies I’m working with: Node.js, Mongo.db, servers.

My idea is: Creating a web application using a Node.js server that uses node-exif to get exif image data, save it to a MongoDB database, analysing it and returning it in a user-friendly interface, providing details about similarities between the images found.

The project has already been approved so it’s up to me to put al the pieces together: - Setting up Node on server - Setting up website with image upload. - Setting up MongoDB and saving data from images as objects - Displaying analysed data on website.
