Thermostat

The simple challenge was simple, to build a Thermostat with a few basic functionalities.

User stories

As a user,
So that I can set the temperature hotter
I want to increase the thermostat's temperature.

As a user,
So that I can set the temperature cooler
I want to reduce the thermostat's temperature.

As a user,
So that I can save power,
I want to be able to switch power saving.

As a user,
So that I can restore factory settings,
I want to be able to reset the thermostat.

As a user,
So I know the energy usage of the thermostat,
I want to be able to ask the thermostat the current energy usage.

Quickstart

First, you would need to clone, change directory and install the dependencies running the following commands:

git clone git@github.com:georn/Thermostat.git
cd Thermostat
npm install

• Then to run it locally run the following command and enter localhost:3000 on your browser:

npm start

• If you want to run the tests

npm test

Development

The challenge is complete and here is a couple of demos of the application.

Basic Functionality of the Thermostat

It is also connected to a Weather API to get the temperature of different cities!

But there's always room for improvement and also I also would have liked it to look cool!

So, after leaving this code to gain some dust for a few months, I decided to start to refactor it for the sake of practice.

Rather than have the HTML document live by itself, I decided to go and put it on top of an Express.js server to also giving me the opportunity to take away the standalone Jasmine testing frameworks and bringing it as a package and ultimately step a notch on the application code.

The next step is to add styling to the application.

Main Tasks

• Thermostat starts at 20 degrees
• The minimum temperature is 10 degrees
• If power saving mode is on, the maximum temperature is 25 degrees
• If power saving mode is off, the maximum temperature is 32 degrees
• Power saving mode is on by default
• Less than 18 degrees is low usage of energy
• Less than 25 degrees is medium usage of energy

Collaboration

This amazing people collaborated to the code, but by that time I wasn't a good git collaborator, so I didn't document it. Thus, it is now when they have their credits.

Tech Stack

Here is a list of the technologies used:

• Javascript ES5
• JQuery
• OpenWeather API
• Node.js
• Express.js for a Web Application Framework
• Pug for a Template Engine
• Jasmine for Testing
• Istanbul for test coverage
• Travis CI for Continuous Integration
• Coveralls for web hosted test coverage
