Virtual Pet JavaScript

This project demonstrates how to mimic a modular environment with testing capabilities. Frameworks like React will come out of the box with the testing and transpiling tools needed to create modular components that can be tested. Without a framework we are using the following tools:

• Node
• Parcel
• Babel
• Jest

Getting Started

To get started clone this repository and run npm install . Be sure you have node already installed on your machine. You can check this in your terminal by running the command node -v

Want to set up this project from scratch?

Not wanting to clone, but want to practice the set up of the environment yourself? The following steps will allow you to set up this project from scratch

• mkdir virtual-pet-js

• npm init -y to set up a package.json file and accept the default settings

• npm i --save-dev parcel jest babel-jest @babel/core @babel/preset-env to install Parcel, Jest and Babel

• create a .babelrc file and add the following snippet to this file:

     {
        "presets": ["@babel/preset-env"]
    }
  

• Edit the scripts in your package.json file to read as

    {
        "scripts": {
            "start": "parcel index.html",
            "build": "parcel build index.html",
            "test": "jest --watchAll"
        }
    }
  

• Create a gitignore file at gitignore.io

  • add Node and VisualStudioCode to this gitignore and bring into the project

Interacting with this application

• npm test will run the tests
• npm start will run the application
