Can a single variable be different in dev and production environments? How should I define this variable to handle the distinction? Is checking the location URL a suitable solution for achieving this?

Within your package.json file, you have the ability to define environment variables within the
script section. An example of this would be setting NODE_ENV=production for the build script:
{
"scripts": {
"start": "npm run dev",
"dev": "./node_modules/.bin/webpack-dev-server ...",
"build": "NODE_ENV=production ./node_modules/.bin/webpack -p --config webpack.production.config.js"
} ... }
Subsequently, within your JavaScript code, you can check for this variable using the process global object:
if (process.env.NODE_ENV === 'production') { ... } else { ... }
