Thermostat

This is a simple thermostat app with below specifications.I built this app to learn React and how to build code infrastructure using Terraform.

Specification

• Thermostat starts at 20 degrees
• You can increase the temperature with an up function
• You can decrease the temperature with a down function
• The minimum temperature is 10 degrees
• Flash message when user tries to decrease temperature below 10
• 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
• You can reset the temperature to 20 with a reset function
• You can ask about the thermostat's current energy usage: < 18 is low-usage, < 25 is medium-usage, anything else is high-usage.
• Add a server
• Deploy to Heroku
• Infrastructure as code(Terraform)

How to use it

• git clone git@github.com:reenz/react-thermostat.git
• run npm install - to install all the dependencies
• run npm start - to start the app and visit localhost:3000
• run npm test - to run the tests

Technologies

• React
• Jest
• Enzyme
• Babel
• Terraform

Building Infrastructure using Terraform

• set environment variables HEROKU_API_KEY and HEROKU_EMAIL
• terraforn init to initialize
• and then terraform apply so that it scans the current directory for the configuration and applies the changes appropriately
