Lab description

In this lab, you learn how to setup and install Nodemon and Dotenv NPM Packages. Nodemon is for application development monitoring that will restart your server when code changes are made. Dotenv is for loading environment variables into your Express application. Nodemon and Dotenv are valuable tools to help ease the development of an Express application. For this lab, you will be asked to work with the terminal along with making application configuration changes to setup an Express development environment. For this new series of Express labs, you will be instructed to work inside a specific file or set of files. If this is your first time working on the new Express lab, make sure to watch the Introduction to Cloud Academy Coding Labs.
