Let's set up our app environment, as follows:

1. Create a new React app called LCApp using npx, like this:

npx create-react-app LCApp

2. Update your package.json to the following values:

{ 
 "name": "lcapp", 
 "version": "1.0.0",  
 "dependencies": { 
 "bulma-start": "0.0.2", 
 "react": "^16.4.2", 
 "react-dom": "^16.4.2", 
 "react-scripts": "1.1.4", 
  "web3": "^1.2"
 }, 
 "scripts": { 
 "start": "react-scripts start", 
 "build": "react-scripts build", 
 "test": "react-scripts test --env=jsdom", 
 "eject": "react-scripts eject" 
 } 
}

3. Run npm install on the Terminal window to install the dependencies.
4. Next, within the src folder, create a Components folder for the app components. Also, create a contracts folder within src. We'll be using this to map the contracts being used by the app.
