Differential Team database: how to build

Install postgreSQL:
https://www.postgresql.org/download/
Add PostgreSQL/[version, either 12 or 13]/bin and PostgreSQL/[version, either 12 or 13]/lib to PATH (on Windows) or make it an environment variable on Mac/Linux
in command prompt or terminal, call psql -U postgres -f [full filepath to database_setup.sql]. note: The file database_setup.sql can currently be found in the erd-implementation branch in the database folder.

run npm install all within the directory containing package.json to install all dependencies for the pg package, which is the library used to communicate between the PostgreSQL database and the react.js app, as well as all other dependencies outlined in the package_lock.json file
In goon-universe, the app can be run with node app.js.
Using the functions outlined in queries.js, which implements the REST API enumerated in app.js, frontend teams can now interact with the database from their React.js app as usual.
Worth noting: the pg package's use depends on certain user credentials used to access a common database (namely, the username/password for the postgresql database which you've set up using database_setup.sql). Since the git repository is public, it's a security risk to store these credentials in public on the clear web. Thus, we are using a .env file (locally, for now) to store these credentials. You will not be able to access the database from the React app without a properly configured .env file!

Install Node.js:
https://nodejs.org/en/download/
Go into the folder frontend in the command line.
Run npm install in the command line to install all dependencies required to run the app.
Run npm start in the command line to start the app.

in command prompt or terminal, run psql -U [user] -f [full filepath to insert_example_data.sql]. This file can currently be found in the erd-implementation branch in the database directory.
