Create API credentials for Spotify and PostgreSQL

• Navigate to your Spotify Developer Dashboard and create the App "spotify-playlist-creator". Save the Client ID and the Client Secret for Step 2. Add your Spotify credentials in the Users and Access tab of the App you just created in your dashboard to grant your account with permission to access the App.
• Navigate to ElephantSQL and follow the steps to create an account and then create a new database instance. Once the instance is created, save the revealed URL for the next step.

Create a .env file in the root directory with the following information:

SERVER_PORT=3001
DEV_PORT=9001
NODE_ENV=development
SPOTIFY_REDIRECT_URI=http://localhost:9001/
SPOTIFY_CALLBACK_URI=http://localhost:3001/callback
SPOTIFY_CLIENT_ID=<PROVIDED_BY_SPOTIFY>
SPOTIFY_CLIENT_SECRET=<PROVIDED_BY_SPOTIFY>
PG_URI=<PROVIDED_BY_POSTGRES>

Run the following command to install dependencies:

npm install

Run the following command to run the webapp in development mode:
