Setup Instructions

1. Clone the repository to your local machine.
2. Navigate to the api folder and run npm install to install the necessary dependencies.
3. Create a local PostgreSQL database and copy its database URL.
4. Go to the GitHub Developer Settings or the Google Cloud Console (depending on what OAuth systems you want to include) and create the necessary OAuth application. Then, copy the Client ID and Client Secret.
5. Create an .env file in the api folder (copying the existing template in .env.example) with the following environment variables:
   • API_PORT: the port number for the API server (prefilled)
   • CLIENT_URL: the URL for the client-side of the application (prefilled)
   • DATABASE_URL: the URL to your PostgreSQL database
   • SESSION_SECRET: a secret key for Express session handling
   • GITHUB_CLIENT_ID: the client ID for GitHub OAuth authentication
   • GITHUB_CLIENT_SECRET: the secret key for GitHub OAuth authentication
   • GITHUB_CALLBACK_URL: the callback URL for GitHub OAuth authentication (prefilled)
   • GOOGLE_CLIENT_ID: the client ID for Google OAuth authentication
   • GOOGLE_CLIENT_SECRET: the secret key for Google OAuth authentication
   • GOOGLE_CALLBACK_URL: the callback URL for Google OAuth authentication (prefilled)
6. Run npm run dev to start the Node.js API.
7. Navigate to the web folder and run npm install to install the necessary dependencies.
8. Create a .env file with the contents of .env.example. If you have the API running on the same port, it should work; otherwise, update it.
9. Run npm run dev to start the Next.js application.
10. Visit http://localhost:3000 in your web browser to see the running application.
