Node.js APP - Game of Life (challenge #2)

A Game of Life nodejs App coded in Node.js and dockerized

This version of the Game of Life, created in nodejs has been created as a challenge for Habitissimo.

Installation

I have packed the Game of Life app in a docker. In order to run up the docker you just have to execute the below command on the console:

docker-compose up

The docker will be mounted and execute, and so the Game of Life will be started inmediatly. The Game of Life will display something like this on the console:

Development

Node.js

Install the Javascript runtine node.js. The installation process of this package depends on the host environment, so read the documentation carefully. For example, for Ubuntu 18, the process is really simple:

sudo apt update
sudo apt install nodejs
sudo apt install npm

Dependences

Install all dependencies of the app with:

npm install

Running the app

You can start updating the nodejs code and start playing while checking the updated results in the docker with:

docker run -it -v $(pwd):/app node-docker-challenge2

or you can execute on your local environment with:

npm run start

Testing

Several Tests have been developed to check that all code works properly:

• Functions with test cases
• Expected results due the game rules

All the tests have been coded at /test/life.test.js. In order to execute these tests and check that all works fine, execute:

npm run test

Remember:

• Before coding any new feature, code the test.
• After coding, execute the complete set of tests.
• Enjoy it!
